Hands on with the Kent Systems Soda Bottle Cap

I’ve used a Carbonator Cap for a few years now.  It works pretty well.

If you’re not familiar with this, it’s a cap that fits standard 1 and 2 liter PET Soda Bottles.  It has a gas ball lock quick disconnect on it.

The Carbonator Cap:

This comes in really hand for drawing beer off of your kegerator for easy transport.  I know some people also use this for fine tuning carbonation levels for competition.

Kent System Soda Bottle Cap:
More Beer recently introduced the Kent Soda Bottle Cap.  This accomplishes the same task as the Carbonator Cap.

I’ve had this for a while now and I wanted to give you my thoughts on it.

There are two pieces in this.  The blue quick disconnect and the white soda bottle cap.  These are available as a set and individually.

Both the cap and the quick disconnect are valved.  That means that you can disconnect this and CO2 will not leak from either piece.

The 1/4″ barb on the blue quick disconnect fit snugly into 1/4″ ID tubing.  It was snug enough that I felt like it didn’t need a clamp.  The disconnect engages and disengages easily.

The thing I like about the Kent setup the most is…. I can easily hand tighten the cap.  At least for me, the Carbonator Cap has been difficult to tighten without leaks.  I usually use channel locks to tighten it down.  It requires a lot of force to make a good seal.  I was very happy when the Kent soda bottle cap easily tightened.  Because of this alone, I will use this cap every time that it’s available in my brewery.

I am impressed with this product.

Let’s say you want to be able to transport three 1 liter bottles of beer.

    The Kent Carbonation Cap is manufacturer’s part number 4BXP1A. Even though it isn’t listed in the Kent Volume 5 catalog, it is shown on the Kent Systems web site, http://www.kentsystems.com. The body is made of white acetal resin and the description says it comes with a white internally lubricated Buna-N o-ring. You can find it there if you search with its 4BXP1A part number or the terms “male bottle cap”.

    Same here is there suppose to be a washer or something in the lid of the cap i too have tried pepsi and the 1 liter bottles from wally world and cand get it to seal. i have tried different pressures from 50 psi down to 10 and all still leak around thread is their a trick or someting im missing ?

      I believe there is supposed to be a washer, but I would need to check. I don’t think there is a trick, these sealed easily for me. I would give more beer a jangle and see what they say. If you do, can you comment back here so that we know what became of it?

      I went on bargain fittings.com and he told me he ships with silcone o-rings. I also contacted more beer and they said they didnt have washers.Before i tried sending it back I used a Grolsch-type washer in it and it sealed fine. Needless, to say i got a bunch from bargain fittings they were also a $1 cheaper and had o-rings.

    Have you had any issues with the Kent bottle cap leaking? As soon as I connected this to gas I felt co2 escaping through the threads.

      It seems it may be picky about what brand bottle you use. Inca Cola leaks like crazy. A Pepsi bottle also leaks, but just slightly. Do you have any recommended brands?
