I am currently in the process of rebuilding a 1977 crosman760.
When I took it apart there was 40 years of dirt, sand, grease, oil, etc. The o rings were dry rotted, the spring in the valve body was rusted and weak.
So, I made a parts list of what I needed. The cost was around $36 plus shipping.
Buying a brand new 2018 760 is only $29.95 at Wally world.
So I bit the pellet (pun intended) and ordered a new o ring kit from Amazon for $10 plus shipping.
When I got the o rings I thought to myself, "self, I bet Lowe's or home Depot sells o rings" sure enough I was right.
the o rings on top are from Lowe's the bottom ones are kit I ordered.
they are sold in the plumbing area, at about $2.50 per pack and 10 rings to a pack.
The transfer gasket can be made from clear vinyl tubing 1/4" outer with a .17 inner. And you get 10 feet of it for about $2.
Just a heads up.
I am not endorsing any particular brand, just showing the sizes.
