Specific O-ring Size please:)

Postby Nickdizonc » Tue Mar 10, 2015 11:13 pm

I have a minor leak in the valve an gauge port area of my .25 and it is 100% due to bad orings which I'm sure have a few nicks and cuts after my most recent valve installation (GOD I HATE swapping VALVES!). Ace has a ton of orings and I'm sure they have the one I need but just in case does anyobe know the specific oring dimensions of the orings located on the gauge port
( crosman part#AS568b-118) and the one ring on the valve? same ones I believe. Thanks in advance. I need to stock up on these as I am a human oring shredder whenever I tear down my rifles.

It's 118 as you already said, size is 7/8" x 3/32" or 0,862" x 0.103"... ;)

Thanks Stefan! I'm a NOOB to orings sizes so I had no idea that 118 meant a specific size. if you could direct me to a oring reference link that would be helpful. but for now you gave me precisely what I needed. muchos gracias kind sir:)

That would be: http://www.oringsandmore.com/bulk-rubbe ... for-50-pc/

I bought a lot of o ring from that store for my Marauders and Benjamin Hand Pump and they are excellent!

Smoothing out the leading edges of machined cuts in the pressure tube help reduce cuts in the O-rings immensely
