ok im going away for a weekend where i will not be able to pick up anything for the gun so im looking to stock up on supplies now. Can someone tell me all the sizes of the o-rings in the gun and also a good oil to pick up for it.

The valve and hammer orings are a 015 size. The one oring you should stock up on is the valve face oring(where the 12 gram seals). I'm not sure of the size but you can get them from PaintballSolutions for about .50 cents a oring. Its also agood idea to apply some paintball grease to that oring. Paintball oil like gold cup will also work, but as oil is thinner it wont stay in place as long. Really the only other part to lube is the hammer.

so should i not get oil?

When I was repairing Delta markers, I mainly used grease. Paintball oil is not bad to use, but usally its going to end up in the barrel after afew shots.

I used A Dow 33 grease on the valve face oring, hammer and a very little amount on the bolt.

the offending o-rings size is -010 Urethane D90 ... I've used regular Buna replcements from home depot and the sort as well (they just don't last as long).

Part# 29 valve face o-ring

I just recently had gotten some o-rings from Paintball Solutions for my Delta .68. At my work we have a huge selection of o-rings and the -010 does not match up. We ended up using a caliper to figure out the size of the o-ring. The o-ring seems to be a metric o-ring and not a standard. How metric o-rings work is you measure the thickness of the o-ring and the ID not the OD like on a standard o-ring. It seems to measure 2mm thick 23mm ID. I do not think you will find this size in a Home Depot/ Lowes, but McMastercarr has them. I hope this helps.

P.S. I asked Paintball Solutions what size it was and they did not seem to know.
