The seal/o-ring on one of my trim cylinders has dry rotted/cracked/split and aint there no more. I tried to find a replacement seal/o-ring but am not having any luck,looks like you have to buy a new $$$ cylinder just to replace the seal. Is there any other fixes someone can recommend? How long can i do w/o this seal? It's not leaking fluid out but will it somehow suck H20 in?
