Title: i think i knocked out a seal......
Post by: randomgunner on November 22, 2011, 07:34:48 AM

some time ago, i was using sand paper to deburr my 1377 tube. whilst i was doing that, something rubbery like a seal came out. it was near the back end of the tube around the TRANSFER PORT......
it had a really big chunk taken out of it. so now, it appears that i cannot even USE the gun. so, anyone have a good replacement, or am i skrewed and will have to buy from crosman?
also, is there a suitable seal to seal the top of the transfer port?

It sounds like the valve seal came out, you will need to take the gun apart to replace it.
