.177 FX 400 Breech O-Ring Size?

MP44 · Jul 28, 2018

I just happened to take the end cap off to look at the internals of the factory moderator of a newly acquired .177 Royale and could see light around the closed probe so I figured it is time for a new o-ring.

Anyone know the exact size? TIA!!!

According to FX parts diagram it's a 4.3 x 1.5 NBR70 (Part E1-4,5 on list)

I cannot find a 4.3X1.5 o-ring after many google searches, Does anyone have a link to an o-ring supplier or industrial supply co. that sells these by the bag, which will probably be close to what FX sells just 1.

You can buy on ebay. https://www.ebay.co.uk/itm/FX-Airguns-Breech-Pellet-Probe-Barrel-Seals-Choose-Model-/371626802698?var=&hash=item9528441d57.

This guy sells them in packets of 5. Bobcat and royal should have the same o-rings
