Genesis valve parts

[Daved222269]

I’m trying to rebuild old Sherwood 6300 valves. Northeast scuba supply has o-ring kits. It states on their website, seats are not available anymore. Does anyone have a source for seats? Has anyone successfully used a different brand seat in it’s place? Thank you.

they are unique in their shape. same problem as the genesis valves with the yellow seats.

Seats seem to last almost forever. I've rarely changed one except for some almost new LP 98 tanks I got that had soft junk seats that got chewed up in less than a year.
If it will seal when closed, but leaks when open, then the seat is likely OK and other parts (o-ring, teflon washer) need replacement.

Ok thank you. I haven’t even pressurized these used tanks or valves yet. Taking the tanks in for hydro. I just thought it would be good to do a full rebuild. I’ll clean them up and get the o ring kits for them. Thanks

Take one apart. They aren't complicated, but take some pictures or get a diagram if it's your first time.
Having said that unscrewing the valve nut without the slotted tool, especially if it's not had much care can be a bit of a hassle. Get one of those tools. After that it's mostly just a crescent wrench and common sense. You probably will want some 90 duro #010 O-rings and teflon washers.
I hope the kits don't become completely unavailable. I've got a mess of HP 100/80 tanks.

Maybe you check the Trident A208-T1 seat, looks like that could be the one.
Says Sherwood Genesis T1 HP seat.......
