Screwed (?) schrader

FishBoy · Sat Jun 28, 2008 3:56 pm

Ok, i am going to buy the parts for my planned pneumatic and I decided to try to salvage the schrader valve from my first attempt. After trying many things (wrench, clamps, etc.) in hopes to break the epoxy, I decided to use a blowtorch since epoxy is heat-sensitive. Anyway, I'm not sure if it's safe to use or not so I figured I'd ask. As far as i can tell the (bottom) threads are ok and the valve functions, I'm just making sure there isn't something I don't know about.

It should be fine.

What pressures do you plan on running it at?

FishBoy · Sat Jun 28, 2008 4:23 pm

probably 120 psi max

pizlo · Sat Jun 28, 2008 4:53 pm

Your defiantly ok. Even if it broke on the inside when pressurized you'd probably just get a bad leak.

Myself, I prefer a male quick-connect and a 1/2" ball valve.

Just why did you epoxy it?
The joint should have been good enough not to use any bonding agent to stop leaks.

It should still work well, but the heat from the blowtorch may have melted the rubber seal inside the valve. You may need to get a new valve stem for it. (You could just take the valve stem out of a bike tire or other schrader valve.)

ok, i keep hearing about quick connects, where can you get them, can they be used with a bike pump, and how much do they cost?

People really shouldn't suggest bad solutions, and not even explain them. A quick connect is 2 fightings, and one slides into the other and then air can pass through. Many compressors use this fighting. If you're using a bike pump you'd have to get some adapters and such to make it all work, so you're making more of a problem than buying a new schrader.
And seeking at least TRY to help...

$7 for a 1/4" at home depot in the air tools section. You'll also need a ball valve and a 1/4" to 1/2" brass flip connector from the plumbing section. (The isle across from the PVC isle, should have sprinkler valves in it to.) If you want to use it with a bike pump, screw your schrader into a female quick connect. It's useful for when you get a compressor.

... Actually, keep using your schrader valves until you get a compressor. THEN start using quick-connects. They become very useful after that.

I suggest getting a tire chuck rather than a quick connect. If you don't know how they look like, they look like these: http://www.pneutrend.com.tw/Img_Product ... 20copy.jpg
That one is a female, and this one is a male: http://www.pneutrend.com.tw/Img_Product ... 20copy.jpg
And by the way...do those things act like schraders, or does air just flow through?

Ummmm.... What's a new schrader valve cost... $2?

The proper term for something that can be screwed in because it has threads is "threaded" not "screwed".
Screwed means its fucked up, and its not.
