Good Afternoon... I was wondering if anyone might known about the breech seal for the "new model 2014-2018" Feinwerkbau Sport air rifle. It appears to be an o-ring probably 90 durometer... does anyone know who might sell them here in the USA? Many thanks and have a great day!!
Breech Seal O-Ring Feinwerkbau New Model Sport -NEED Some Help!!
- Thread starter Old-Mr.Jack
- Start date
There is this supplier in the UK. I have bought from them in the past, no trouble at all. I would definitely contact FWB directly and get the specifications or part number for the o-ring to verify it is the same as for the 124/127. They have helped me before and responded very quickly. If you do get the o-ring specs for the new Sport, please pass them along. If you obtain an o-ring, measure the dimensions: ID, OD and cross section before installing it, and pass that information along as well. Good luck!

I talleyed up all the rebuild orings I needed for my springers, pistols & PCP guns and made one order. Think I'm set for life on orings. Reasonable prices and USA company.

Thanks for the responses. The "New Model" Sport (2014-2018) has a different seal than the "Old Model" (1973-1986) for some reason and will not interchange. The "New Model" is very similar to the seal that Diana presently uses. No one stateside appears to have FWB replacement stock. It may be some time before I have any information but when I do I'll make sure to post it. Best Regards and Have a great weekend!!

I've confirmed with Sarah Siepmann at FWB directly - the breech seal for both the FWB 124 and the newer FWB Sport are the same. Her exact response:
"The O-Ring 10,0 x 3,0, item number 4.9.0004 is installed in the model Sport as well as in the model 124/127.
The item number 4.9.0004 is a replacement article for item number 1200.113.3 which is mentioned in the exploded view of model 124/127."
It's easy to find replacement breech seals for the FWB 124... so that's the final answer.

That's good info!!!
McMaster Carr is another good source for orings here in the states! Every size under the sun.

The issue with finding a non manufacturer replacement breech seal is
locating one with the same wall thickness. Thickness is critical!
