Schrader valve cores

Post by CaptnJack » Tue Feb 23, 2016 10:29 pm

Does anyone know where I can easily find some spare schrader valve cores for the ends of BC hoses and the like?

Pep Boys, NAPA, or the like? Maybe Les Schwab? I'd figure that just about any tire shop should have them.

Are they stainless at an auto shop?

Don't know, but not sure that it matters. Are BC hose connections made of stainless, or brass? I thought it was the latter.

I understood that the schrader valves for BC's were the same as used for tires. There may be certain items that do require a larger valve, which are sized to fit industrial tires.

Pep boys carries a package of valve cores, branded by Slime. They are silver in appearance, but there's no mention of what metals they are made of.

I'm not so concerned about BC hoses, but the same core is used in the diluent add valve on my Meg and I wanted a couple spares for my save a dive box.

I don't know if this is important in your application, but schrader cores are made with different compounds in their sealing gaskets, different flow rates etc. In my previous life we had to use the manufacturers replacement to make things work right. I wouldn't think flow rate would be a big deal, and if the only thing contacting the seal is air, it shouldn't be any different than a tire valve.

Schrader valves have gone thru changes as well with the advent of nitrogen filled tires, and aluminum alloy tpms valves stems. For our purposes, the brass colored valves are not desirable. The ones to use are the silver colored valves. They are the ones I have given to divers over the years.
