O-Ring size for WGP 3 way splitter valve?

[gogi19]

EDIT: BrickHaus and Jordan nailed it. It's a PPS Quickswitch which after some digging, uses standard 003 rings for the stem (some reports of thicker polyurethane or 75Duro seals working better) and an oddball 46-224 or metric 1.2x5.7mm o-oring for the valve seals.

I was hoping someone could confirm the size of the o-rings on the 3-way splitter valve thing that came off a 2K5 WGP Prostock. The old ones were just goop so I couldn't get a reliable measurement off them, 009's seem too tight a fit in the housing and 008's don't really fit on there easily. Just wanted to make sure it's not a weird metric size and cross section before chasing my tail.

Pretty sure that's a pps quick switch, and they are a proprietary o ring.

If you read that thread they have figured out that metric o rings work.

I believe you need 1.2x5.7 metric rings.

Thanks y'all! I'm still very new to autocockers and didn't know this was a Palmers part. I'll grab a rebuild kit or some metric o rings now. This prostock had clearly been sitting in an attic or garage for some years and had all the seals toasted.

PPS is still shipping orders, probably worth grabbing a rebuild kit if they're available.

Thanks ! I went ahead and picked up 2 sets! I'm waiting on a few other parts from acparts anyway so looks like it won't be back together for a week at least lol

Pretty sure this is not a PPS product.
Unless they have put in a new style of quickswitch internals.

The PPS quickswitch uses 4 separate cup pieces held in with a hollow screw. The stem passes through the front and out the back.




This looks to me like a WGP Adjustable STO. Produced after the CT style I think.
IIRC it uses 4x009 for the spool and 2x003 for the stem.

Oh dang, I think you're right! Thank you for weighing in, the spool is one solid piece so it must be the STO. The STO makes more sense honestly because the test of the pneumatics and internals are stock.
