Sheridan Blue Streak 5mm 4692

I bought captain oring for a silver streak I serviced for a friend and for my 392. If you can't find a piston seal, there's ways to cheat and soften up the old one. Products for cars that leak oil often just swell your rubber seals and soften them, which can be used to your advantage. We will cross that bridge later if you're interested in that avenue.
 
Thanks, appreciate the info, you mentioned softening the plunger. I hadn't thought about that. I might try that until I can get a plunger.
Thanks again

I get all my kits for Sheridan and crosman pumpers from "precision pellet" great service, low prices, fast shipping, and the kits are basically OEM drop in parts.
Have fun
