Crosman 38C, I Spoke Too Soon...

I guess I spoke too soon as I found the 38C had leaked out all of its gas on Sunday morning. So I took it apart again and decided the 38-094 Valve Seal was the likely offender, as it looked a tad discolored and possibly had some cracks.

So I turned up a replacement seal from 95 durometer urethane rubber. It'a bit softer than the seal in the pistol but it should seal well.

I took the time to sand the faces flat and smooth. I replaced it in the gun and it sealed fine. As of this morning it's still holding gas with no evidence of leaking. Teflon, Nylon or Delrin might have worked as well, if it develops a leak again that's what I'll try. But for now it's all fine.

I ordered the 38A027 (piercing pin) and 38-128 (End Seal) from Crosman this morning, 6 of each for about $21.00 w/ shipping. You know, just in case...

Oh, I thought I'd mention that Derrick has a winning entry up in the Crosman "Summer House". I can't hardly wait to hear what he won. It's a great story especially if you like old Crosman guns.

Next project for the blog? I'm working up the nerve to take apart my BSA Superstar with Theoben gas ram. We'll see what happens.

I need to order the 38-128 (End Seal) from Crosman. Can you help me with their email and tel nos. Do you know if they will ship to India. Or can you arrange a couple of those for me from your spares ?

i have a problem with my crosman 38c. it doesnt hold the gas. i need help from someone that knows the guns well. i looked at your site and figured out the problem. the largest seal in the last chamber before the opening where the pelet is placed is shot. i was wondering if i could order one or pay you guys to build me one? i just need the one seal to make the gun stop leaking. i would really apriciate if i could get this gun working for my grandpa again. thanks

A little fyi for everyone here attempting to rebuild their 38T/C.. from experience, the most crucial seal in the valve assembly is the 38-094. It should be,(but I say MUST) be the original orange one. Trying to haggle or compromise with using a close substitute is more of a waste of time and money. Also the 38-130. These are the two most important seals who's job is to hold the gas pressure inside valve body from escaping and withstand that cold Co2 gas temperature. I recently bought a rebuild kit on ebay and the 38-094 black seal it contained seemed more like a faucet washer seal. Once i stalled it leaked the gas. So I feel its best to do it the correct way the first time. And by the way, in regards to a queation on the value of this famous Crosman 38T, it does have a substantial value, of upto $200 in great condition.
