R134a Can Tap

[[XC] gomeler]

I never thought I'd need r134a but now I need a few ounces for a chiller I'm building. I biked to all the stores in a 2 mile radius of my house and I can't find a r134a can-tap with a shraeder fitting, they all feature the automotive fittings. The one shraeder equipped tap on ebay pierces the sidewall, I'd rather have a tap that pierces the seal on the top with the threads, anyone know of a source for these taps? Purchasing a 30lb cylinder of r134a is out, I wouldn't use 30 pounds of the stuff in my lifetime.

so you need a can of r-142a to connect to a shraeder valve? you could cut the hose from the can, and then cut a hose with the shraeder fitting on it. then join the two by using a doubble hose barb.

Suppose I could do that but I was hoping for a complete system, not something ghetto-fabbed up. If nobody gets back to me soon then I suppose I can use something like that to transfer the contents from the r134a cans into another proper cylinder.

yea it is ghetto, but if you cant find anything, it may work.

they all had a brass vavles with 1/2 acme threads that screws right on. and have a piercing valve,use what you need and shut off

I keep a can ,tap and 8" hose in every vechicle, if you develope a leak and its slow you can add enoughn gas so the low pressure limit does not keep clutch from engaging. bike ridiing is good exercise, towworow ,but put a gp transmitter on bike so we can track you.

Whats wrong with puncturing the side?

Bike riding indeed is good excercise but I prefer running, ran 6.5 miles on wednesday though so I thought I'd give my legs a break from the shock of running in the city. Would be funny to put a GPS transmitter on the bike, was all over the place today. I mainly don't want the side-wall puncturing taps as I have all of my gases stored in a large wooden chest and I wouldn't want the side-wall tap from getting jostled and then leaking the remaining ~8 ounces of R134a, with something that threads onto the can then a leak is less likely. Silly but I try very hard to not vent any non-HC refrigerants. Picked up a threaded can-tap that'll tap into the top seal on the can and it has a valve so I can shut it off and store it, hopefully the thing forms a good seal. Thanks for the help guys, time to go watch Shrek 3 :)

One for these ^

$7 @ Hardware store.
I bent mine so it fits the arc of the can better. You have to make a strap out of sheet metal etc.. Like a giant vamp clamp :D It even shuts off.

Thanks but I didn't want to pierce the sidewall, I wanted everything to be done via the top. Found a solution though, thanks :)

thats to tap a copper line to feed water to fridges cold water & ice maker,plus other item like humidifiers and the like

As such refrigerant will go through the rubber seals of that clamp, it is useless for refrigerants. For water it is perfect, for refrigerant no.

[gkiing]

Huh? Refrigerant doesn't go through the rubber seals on my gauges :p

Thats becuase the rubber on your guages of a perticuler type, just as the rubber for water service is of a perticuler type and so on, not all rubber is simply rubber.
