Making a Utility CO2 Line Using Luer Lock Disconnects

Luer Lock are an inexpensive and effective disconnect system.  I think these are typically used in the healthcare industry, Luer Locks provide a solid, pressure capable connection with a quick twist.

You could use Luer Locks throughout your primary disconnect system throughout your kegerator CO2 system if you wanted to.

I used valved QDs for most of my keg lines, see below, and Luer Locks to operate a “utility” CO2 line.  One of my CO2 lines has a female Luer Lock on it.  I have a selection of attachments that consist of: The attachment, 5 inches or so of CO2 line and a male Luer Lock.

With this setup I can easily swap out more specialized attachments that I don’t typically need to be hooked up all the time.

Tip: In my experience it can be difficult to get tubing onto Luer Locks.  If you have this problem, try soaking your tubing in warm/hot water.

1/4″ Cole Palmer Luer Lock Disconnects + Making a CO2 Utility Line

Cole-Parmer AO-45502-20 Female luer x 1/4" hose barb adapter, Nylon, 25/pk

Luer Locks disconnects are generally used in medical and industrial applications.  Compatible male and female Luer Locks twist together to make a airtight, pressure capable connection.

I use Luer Lock style connectors for a CO2 utility line for my draft system.  That allows me to quickly and easily switch between a number of CO2 utility attachments that I don’t use on a day to day basis.  The reason I chose Luer Locks is that they are generally inexpensive.  You could also use these as a primary disconnect for your CO2 system.

These Luer Locks are made by Cole Parmer.  They feature 1/4″ barbs to connect to compatible tubing.  I asked the manufacturer for the PSI rating of these disconnects.  I was told… “Thank you for your email. the fittings AO-45502-20 and AO-45505-19 are male and female fittings and compatible. The Psi rating for these fittings together is 100PSI”.

New from Brew Hardware – Camlock Garden Hose Quick Disconnects

I’m a fan!  I’ve used Cam Lock QDs my kettles, mash tun, pumps and tubing for a long time.  They have worked great for me.  I put male connectors kettles, mash tuns and pumps and use female connectors for tubing.  Standardizing on this (or the opposite) means you can use tubing as jumpers and always have the availability to connect your gear.
