Hog poppet oring size

[Candiru]

I’m in the process of rebuilding a hog zenith second size. The diagram appears to have a 2mmx1mm oring in this position. I have a ton of 2.2mmx1mm orings for scubapro.

1. Can anybody verify if this is the correct size?
2. Can I get away with using a 2.2mmx1mm oring
If no then...
3. Does anybody want to do an oring exchange with me for some 2.2mmx1mm orings?

thanks!

If you've measured the seals and they dimension out the same, perform a balance chamber test. Find a very flat surface and stand the poppet seat side down. Now with no spring installed push down on the balance chamber to see if pneumatic pressure builds up inside the poppet/chamber assembly. If the balance chamber bounces back up-you should be golden.

Any input on durometer 70 vs 90 for the poppet?

The Scubapro S-wing poppet uses an EPDM shore 70 2.2mm x 1.0mm for the poppet/balance chamber seals.

Any chance of setting up a US based distributor? Also I wanted to give a shout-out to deep six for using the much more accessible 006 oring in their 2nd stage poppet.

The deep six manual shows 2.4X.82 N70 O-ring for second stage poppet, part # 1O-EKM-2.4X0.82-06.

You are correct. However I have it on good authority that if you send your reg in for servicing it’s coming back with two 006 duro 90 polyurethane rings in that position.

Interesting, both the choice of duro 90 and polyurethane seem strange for that application. There is a substantial size difference, see this picture of oring I removed from deep six poppet compared to -006 on size chart.

In order to assist all of us with scuba o-ring identification, we have created (after a lot of effort ) the first o-ring identification working mat with 115 different o-ring sizes that are commonly used in the scuba diving industry aiming to cover as many brands as possible.

We know first hand what is to search for the correct o-ring size (not to mention identifying it and printing it on a mat)
Merry Christmas to all
