Gas and gas cylinder safety

We love you and also we desire you to stay safe. Please take fist with any type of compressed gas and gas cylinder.

You are watching: How to tell if a co2 tank has a siphon tube

Always make sure the valve is fully closed when you’re done utilizing the cylinder.Keep every cylinders in one upright positionDo not disclose the tank to excessive weather conditions. High temperatures deserve to increase the cylinder pressure beyond safe limits, leading to malfunctions and safety decaying bursts

Honestly, we don’t recognize for sure. V so plenty of uses for kegs, gas cylinders, and even parts, plus the threats of not correct use, we can’t verify or check you’re to buy the correct items.

It’s as much as you. You re welcome make certain that you space purchasing the right and safe article for her intended use prior to you buy. Your local cylinder filler is terrific resource because that the information you need.


All of ours CO2 tanks have actually a typical CGA320 valve top top them and also are compatible through the standard CO2 regulator fitting.

Our nitrogen/Beer Mix cylinders have actually a CGA580 valve, an inert gas valve offered for nitrogen, mixed nitrogen & CO2, and other inert gases (helium, nitrogen, argon). You should use a nitrogen regulator v Beer Mix / nitrogen tanks due to the fact that the valve and also regulators are designed for the higher pressure.


All cylinders have actually a to produce date. Recertified cylinders likewise have a certification date. The most recent date on the cylinder is the currently energetic date.

The most important day to understand when purchasing a cylinder is as soon as the cylinder was last recertified. Recertification consists of hydro-testing. The room of transportation (DOT) requires that many portable CO2 tanks, both new and used, be recertified every 5 years. Nitrogen and also other high pressure inert gas cylinders normally have a 10 year recertification necessity (although there room exceptions). Certification should be perform by a DOT-licensed facility.

The date of the last recertification is the 8 number stamped across the neck of the tank. The very first two (which are larger) space the month, and the last two space the year in i m sorry the tank to be tested. The four smaller number in the center is the dot registration variety of the recertification facility. The cylinders us offer normally have been certified within 180 job from the moment of sale.

No issue if you’re to buy our products for brewing or any type of of the other thousands that gas applications like gaining your weld on, developing a beautiful aquarium, since our prices renders you want to drink, or since you’re filling tires … please drink responsibly and also use caution with any type of compressed gas cylinder. We’d choose to view you again.


What room the precise dimensions of stole CO2 cylinders?

Steel tanks will have actually variations even when ordering the exact same size cylinder. Depending on the manufacturer, the cylinder’s dimensions may vary a pair of inches. We offer an approximate height and width of the largest typical dimensions.


Can i run right CO2 native a Beer Mix tank?

Generally, nope:

The valve and also regulator in a beer mix setup is details to nitrogen running at a higher pressureThe valve opened is too huge for CO2 regulators
My gas it is provided is offered up as well quickly!

That’s not really a question, but take a look in ~ a couple of things:

Check because that leaks making use of a soap and water solution. It will bubble wherein the leak is. Check the keg as well as the cylinder, as leaks can occur anywhere.Check that the gas disconnect is locked tightly and also that the hose is tightly clamped to the regulator.Check to check out if her hose clamps are too tight. Overtightening can give the hose a small cut that will leak under pressure.
How numerous kegs deserve to I to water from my cylinder?

Generally, the takes about fifty percent a pound of CO2 to pour a quarter barrel of beer, and also one lb to to water a fifty percent barrel.

Here’s part approximate number to aid you select the right size for your setup – choose the keg size, and also click to uncover out the pours per cylinder size. Her actual results might vary.

5 Gallon Keg


2.5 lb. Cylinder = 7 to 11 kegs

5 lb. Cylinder = 15 come 22 kegs

10 lb. Cylinder = 31 come 44 kegs

15 lb. Cylinder = 46 to 66 kegs

20 lb. Cylinder = 62 come 87 kegs


Sixth Barrel (5.23 Gallon) Keg


2.5 lb. Cylinder = 7 come 11 kegs

5 lb. Cylinder = 14 to 21 kegs

10 lb. Cylinder = 29 come 42 kegs

15 lb. Cylinder = 44 come 63 kegs

20 lb. Cylinder = 59 to 83 kegs


Quarter Barrel (7.75 Gallon) Keg


2.5 lb. Cylinder = 5 to 7 kegs

5 lb. Cylinder = 10 to 14 kegs

10 lb. Cylinder = 20 to 28 kegs

15 lb. Cylinder = 30 come 42 kegs

20 lb. Cylinder = 40 to 56 kegs


Half Barrel (15.5 Gallon) Keg


2.5 lb. Cylinder = 2 come 4 kegs

5 lb. Cylinder = 5 to 7 kegs

10 lb. Cylinder = 10 come 14 kegs

15 lb. Cylinder = 15 come 21 kegs

20 lb. Cylinder = 20 to 28 kegs


Note the a correctly filled cylinder must read ~750 PSIG at 72 degrees. Pressure will rise as heat increases, and also go under as the temperature walk down.

Tank need to read ~750 PSIG until the fluid CO2 is gone and the cylinder is nearly empty. Decreasing push is informing you the cylinder is almost done.


Got any tips for serving nitro or cold brew coffee from my kit?

Cold Brew and Nitrogen-Infused Coffee Tips

Coffee is a very personal expression the taste and art. We’d never ever presume come know much more than you around cold brewing your coffee, for this reason we’ll leaving that part up to you. Once it’s brewed, though, we can aid you serve it up from your brand-new kit.

General Cold Brew and also Nitro Coffee Pointers

Always make sure that the coffee you include to her keg is cost-free from grounds and other debris. This keeps lines and also faucet flow smoothly. It’s specifically important because that nitro coffee taps. They have a perforated disc within the tap human body (it creates that good infusion/cascade) that have the right to clog easily.

Nitrogen cylinders have the right to be filled at welding supply stores, gas suppliers, and also some homebrew stores.Keep her coffee fresh by cleaning her lines, tap, and keg regularly. Clean instructions can be uncovered on our website under information > Instructions.

For Cold Brew Coffee Only

Cold brew coffee requires an extremely low nitrogen gas pressures to provide smoothly. Begin with your regulator collection around 5 PSI and also experiment up and down till you acquire the pour you want.

Cold brew coffee is dispensed v normal beer faucets. They have actually no interior restrictions, for this reason if your press is too high, you’ll acquire a foamy coffee bath. Again, start low, occupational up.

You execute not need to take any type of special actions to infuse her coffee through nitrogen. Nitrogen only offers pressure to gain it native keg come tap.

For Nitro Coffee Only

You’re serving coffee that is infused v nitrogen – and you must do the infusing. Two methods to execute it:

The “works OK” way: fill the keg v coffee, attach the gas, pressurize the (35-40 PSI), and shake it/roll it approximately on the floor or your knee for rather a while. Yes, we’re serious. This it s okay the nitrogen right into the liquid. You’ll have to do this every 4-6 hrs to keep the infusion up. Note: be really careful if you select to usage this method. Kegs room heavy and the keg and cylinder are under comprehensive gas pressure. Practice caution to safeguard yourself and also those roughly you.The finest way: usage what the beer guys speak to a “carbonation lid.” for you, the an infusion lid. The lid has a gas connection point that leader to a size of hose with a carefully perforated rock on the end. This reaches to the bottom of your keg and also bubbles the nitrogen increase from below, infusing it through tiny nitrogen bubbles as it goes. Short (5-6 PSI) pressure and about 20 minutes is all that’s compelled to med the coffee; an ext time may be compelled to reach serving pressure in the keg. This is a lot less challenging than the very first method, and much simpler to freshen up transparent the day. They’re easily accessible on our website under the Cold Brew and also Nitro Coffee Kegs food selection or in ~ goo.gl/qtSF4m.

Important note: nitrogen doesn’t want to stay infused in a liquid. The moment you placed it in, it’s trying to separate ago out.

You will should re-infuse the coffee at intervals transparent the day. You’ll recognize it’s time when the cascade stops happening, and as friend get more experience you’ll find out the intervals that work ideal for you and also the outcomes you want.

Nitrogen push for putting nitro-infused coffee is much greater than cold brew. Begin at 35 PSI and also experiment until you get the feel and froth friend like.


We market siphon tube installation for specialized applications that need liquid CO2. Although over there are miscellaneous uses because that siphon tubes, lock are commonly installed in larger tanks (such together our 35 lb. And 50 lb. CO2 cylinders) and also can be used because that refilling smaller sized CO2 cylinders.

If girlfriend would like to include siphon pipe installation to your cylinder order, choosing it independently and add it to your cart. Please keep in mind it will take an additional two come three company days to install and ship, and there is one extra fee for installation. Friend will understand the siphon tube has actually been installed because the letters ‘ET’ will have actually been stamped on the neck of the valve.

Note: over there are additional external components needed to finish transfer come a smaller sized tank. Us don’t bring those parts, and also we can’t check what item are crucial to complete the refill. Please make certain you have actually the correct parts, knowledge, and also skill before attempting to refill any kind of gas cylinder.


All cylinders have to be manufactured and also certified come a well-known standard. The united state Department of transport (DOT), transport Canada (TC), and UN/ISO all have developed cylinder standards.

UN/ISO standards are more recent than DOT/TC standards, and also UN/ISO cylinders are identical to and also in numerous ways exceptional to DOT/TC-rated cylinders:

UN/ISO is a universally recognized global regulation because that compressed gas cylinders, and UN/ISO cylinders room approved for usage in almost every country approximately the world. UN/ISO cylinders can cross nation borders and still be filled easily.UN/ISO company pressure is in ~ or above the typical fill press of a dot cylinder through a +10% overfill designation. These higher capacities permit for UN/ISO cylinders to be easily integrated into a fleet of DOT/TC cylinders.UN/ISO cylinders contain friendly markings with business pressures rated in PSI and also bar.UN/ISO cylinders remain in circulation at maximum capacity for the life of the tank. Due to the higher design ratings for pressure, UN/ISO cylinders carry out not need REE (Rejection Elastic Expansion) testing to attain the common cylinder organization pressures used and also approved in north America. When REE is a an useful and stringent test, DOT/TC cylinders will frequently have their maximum fill push ratings lessened after testing.

Facts and also differences in between UN/ISO and also DOT/TC requirements

Gas filler in the USA have the right to legally fill UN/ISO and also DOT/TC cylinders that fulfill CFR regulations.UN/ISO and also DOT/TC cylinders are made in the U.S. And other international countries.DOT/TC and also UN/ISO cylinders have the same dimensions, inner water volume, steel chemistry, and also valve compatibility.UN/ISO cylinders have actually a higher working pressure and gas volume capacity 보다 DOT/TC cylinders.DOT/TC-stamped cylinders space acceptable for move to, from, and within the U.S. UN/ISO-stamped cylinders must have “USA” country-of-approval marking to be acceptable for transfer to, from, or within the U.S. Our UN/ISO cylinders space stamped “USA”.DOT/TC markings have to conform come the applicable requirements of 49 CFR 178.35, and also UN/ISO pressure receptacles markings need to conform to the applicable demands of 49 CFR 178.71.DOT/TC and also UN/ISO cylinder markings are expressed in standard units.DOT/TC day of produce is expressed together month-year (10-13), if UN/ISO is stamped year (4 digits) and month (2013/01)DOT/TC stamps business pressure just in PSI. UN/ISO cylinders have stamps for both service pressure (PW) and test press (PH) in bar and PSI.DOT/TC walk not require inlet thread file to be stamped. UN/ISO needs the inlet thread profile to it is in stamped.The manufacturer approval number granted through U.S. Department of transport (Pipeline and Hazardous materials Safety Administration) is forced by both the DOT/TC and UN/ISO. If manufactured in the very same facility, the approval number will be the same.Third-party independent investigate is compelled for both DOT/TC and also UN/ISO designs.There is no add to or star for UN/ISO cylinders. The service pressure is currently at or above the 10% overfill authorized for pick gas solutions by DOT/TC.
