FWB C55P cylinder main seal replacement question
Posted: Thu Oct 15, 2015 7:55 pm
One of my cylinders just blew out a seal / o ring .. see the attached pics
I have never seen a green o ring with a flat back before .. probably just from age and taking a set in the tube ..
do I need a specific factory replacement part or can I use a matching standard nitrile black O ring with silicone lube instead ...
your thoughts ?
