Anyone have a part number Gor a hardware store o'ring that fits as a Crosman breech seal?

B12-00-14, for a Crosman Optimus, that would also fit your Phantom and F4 I guess.
You can look up for a specific model here: https://support.crosman.com/hc/en-us/sections/200658060-Crosman-Air-Rifles?page=1#articles
HTH.
Edit: I think a metric 12.5 x 8.5 x 2 mm cross section Oring would fit.

A year ago I bought replacement breech seals for my Crosmans and Beemans from Ar cher air guns dotcom.

I know of no generic seal which would fit. If the old one is not in too bad shape you can try shimming with dental floss behind it.

Just for the record I found out some older China B19 based guns like Quest and Phantom used a different breech seal as far as depth going into the barrel/breech recess pocket. After calling Crosman Teck Dept I found out that older models used a more O ring style shallow seal. In this picture the two seals differ in how deep they fit the pocket ring in the breech. The shallow seal is the older style, and the deep fitting taller seal was the later model style. They look like they are not a rounded face like an O ring. (http://)
