I have pneumatic cylinder on on milling machine tool changer that has a leaking internal seal. It works on the outward stroke but air exhausts out of the back valve on the return stroke.


Does anyone know if I could replace the internal seal on this cylinder?


If not does anyone have a spare lying around?


The cylinder is a Joucomatic Isoclair 435 50 438 c 25 A 150 (P max 140psi)

If you dont come right, I can point you to someone that can help. I bought a missing actuator for my Denford from these guys, were helpful and very good.

Thanks for the replies.
Went to my local pneumatic supplier in Bristol(Harrier Pneumatics) and got a Parker PIA-5025MS-0150 as a direct replacement for 64.
ATC is working fine now.
