Sheridan Silver Streak O ring (Air Rifle)

[Sullyman]

I have a Sheridan Silver Streak ( Pre-Benjamin) from the late 60's. Racine Wisc. 5MM. Still works well (almost) but it need a new O ring for the bolt. When I fire air escapes from the breach thru the bolt. I recall a small O ring being their but it's long gone. Still fires but I'm sure I'm losing pressure and the tomato eating squirrels have to go to their great rewards

Any idea on the size? Can I use one from the local hardware store??

Looks like part #s
.177 = OR046
.200 = OR029
.220 = OR044

What seems to be the closest sizes are
5/64 x 13/64 x 1/16
3/32 x7/32 x 1/16

See dash -004 or -005 on this chart
http://www.allorings.com/size_cross_reference_framed.htm
-003 & -006 don't seem right at all.

The breech measures .200 and center of bolt .095 on mine. The o ring seems to have a cross section of about .085". .085 must be from deformation. The OD seals in the breech and the ID allows the bolt to turn. So I think the 3/32 x7/32 x 1/16 makes more sense but the other size might be it.

Past that I don't know what way to go.

Not exactly what you're looking for...

This is a rebuild kit for the pump-valve mechanism but it does include a replacement o-ring for the bolt.

Found what I needed from Mac 1.Tim McMurray. Great to deal with.

Well-built guns, but horrible to pump and awful ergonomics. Definitely not something you can get ready for use in a hurry. My father has one, and I'm frankly not a fan.

Love em

Have a Blue Streak sitting by the back door that I've owned for 40 years and a relative youngster Silver Streak thats still in the box and never been shot that I've owned for 20 years---still has the manual hanging off the trigger guard--not sure if I'll ever break it out after all this time and the Blue Streak is still working just fine.
