Hands On Review: Universal Poppets

cln_img_0443

I use universal poppets exclusively when rebuilding kegs.  So far, they have worked in every one of my kegs.  I, generally, like their cost and also like the fact that I don’t have to figure out and pay for model specific, OEM parts.

cln_img_0436My 5 universal poppets arrived in bags inside of a bag.  Bags!cln_img_0439Here’s a look at a single poppetcln_img_0443Here it is disassembled.  Poppets generally have three pieces  – a spring, a small o-ring and a stainless piece that holds the o-ring.  This stainless piece has a groove to firmly hold the o-ring in place when assembled.cln_img_0445I have been in the process of testing 008 Buna-N O-Rings as replacement universal poppet o-rings.  Here you can see the two side by side.  The top gasket came with these poppets.  You can see OEM o-ring appears to be just a bit larger.  In spite of the differences I have found that the 008 size has worked on all 4 of the universal poppet styles that I have including this one.  Still testing, conclusions wait for… another post on another day.cln_img_0459I usually flip the assembled top part into the keg body and then put the spring in.cln_img_0460Spring installed.  I’ll then flip everything right side up (trying to hold the poppet in with one finger) and put the assmbly on the keg.cln_img_0461Here it is installed.  This picture doesn’t tell the whole tale, but… This is the gas side of a 3 gallon ball lock keg, mostly filled with water (to save CO2).  I sprayed this with Star San to test for leaks.  No leaks.cln_img_0466I used this gas poppet to relieve pressure.  If I were keeping these poppets in this keg, I would trim the spring the fit was a bit tight.  See tip below.cln_img_0472Here’s the spring after being installed and tested.  Hey.. it’s still a spring.universal poppet I completed this review along with preliminary testing on dash 008 o-rings for use as universal poppet replacement o-rings.  Here’s a picture that will probably end up in that post.  Going through my universal poppets, I initially thought I had 3 distinct styles.  Looking more closely, I believe I have 4 distinct styles.  Two types are very, very close, although I think they vary in length just slightly.

Tip: Universal Poppets the vast majority of kegs without issue.  I have had a couple kegs that ended up being a bit too tight with these.  It’s an easy fix.  Use a pair of wire cutters or Nipper Pliers to trim the universal poppet.  I suggest taking off about half of a coil and testing.  You want the QD to slide on easily and for it to reliably hold pressure when the QD is off.  Taking off a half of a coil and testing helps you make sure you don’t end up making the poppet too loose.
