o-rings for cricket.

Yepper! He put a heck of a tuning on my .25! Hunert yard head shots on turtles ain’t no big thang… If I could post vid’s on here, I could show you guys. I’m amazed at how accurate these PCP’s are!

…and he’s quiiiiiccccckkkk! I emailed him when I saw your post. Within 15 or 20 minutes, I had an email back from Earnest with ordering info. Sent him a PayPal… He’s shipping out the kit, some grease, and a de-gassing’ tool… He’s a heck of a salesman as well as an airgun guru.

Or….you can order a lifetime supply of good quality Cricket o-rings from Ernest, shipped CONUS, for $40.00.

This is from Ernest Rowe (matomaya@earthlink.net) prier post or you can get a 10 years supply o-ring kit from him that include all the sizes.

1. Rotor: The o-ring on the unregulated pressure side of the piston rotor o-ring is a static seal that I replace with a 1.9mm X 3.8MM Buna-N 90 o-ring. that the hardest working o-ring in the air tube, its seal out up to 300B pressure while the rotor in motion when you take a shot, the regulated side of the rotor is 2mm X 10mm V70 Viton o-ring.

2. Regulator OD: on the high pressure side is use 3mm X 24 mm V75 Viton O-ring and on the regulated air side OD I used 3mm X 24MM Buna – N70

3. Air valve end cap: this o-ring seals only regulated air so only 3mm X 24mm Buna N70 required.

4. Fill Valve end cap: this o-ring is subject to 300B pressure so I used 3mm X 24mm V75 Viton.
