Sorry I don't have an answer for you!!!! But I solved my own o ring issue. Did a search on o rings and now I own a entire box of all different sizes.
Then find a good size that fits. What I do.

This thread brings up an interesting issue—spare parts!
Some time back, I upgraded my PC77 (1377) to a steel breach. Crosman shipped it without the bolt, O-ring, and bolt handle! There was even a neat hole in the plastic baggie indicating someone had removed the pieces, and tossed the whole mess back in the parts bin. Proving that every company has a few miscreants! They replaced everything of course (they took 14 days doing it!), but I managed to get an extra o-ring. Good thing, as the one on my 397 wasn't doing its job. Being the guy I am, I ordered 6 new ones since the mailing costs were fixed. So if one fails again, I'm all set.
