RAPS ASA Issue

Hi all,
My RAPS is leaking from the Asa, the o-ring has broke into 2 pieces. Does anyone know what size 0-ring goes onto the piston for the asa? or where I can get replacements?

Thank you in advance!

Hmmmm......if only someone had put together a thread on PBNation that had all of DP markers o-ring charts and schematics/parts lists.............:sarcasticdodgy:

That o-ring is a 3.69mm inside diameter (ID) X 1.78mm cross sectional diameter (CS) in a 90 buna Nitrile material - or also known as a standard -007 in 90 buna .

You may be able to get away with using a 70 buna (slightly softer and easier to find). For stock replacement, check the Dangerous Power website. For the softer, your local hardware store might have it. There are also a few places online where you can o-rings. Just Google it.

So I'm not sure if I have a bad asa, but I replaced the o-ring twice today and cleaned/lubed the oring and was very careful when airing up and degassing the marker but it keeps sheering the oring on the piston... Is there anyone else having this issue or have had that issue before?

Thank you.

Are you using a 90 duro? Have you checked your tank output pressure? Maybe it is a combo of tank creeping pressure and the softer duro o-ring.

Thank you I'll have to check the actual output pressure on my tank. I ordered new o rings from dp website so we'll see.. Thank you for the reply.

Perfect. Hopefully that does the trick. It is also worth the effort to break down the RAPS and give it a good cleaning and relube. Sometimes, what happens is you can get a dirty fill from a field and when that fine dust gets sent through your ASA at 850 psi, it will just shred the o-ring on the ASA pin.
