Waramanga,
The can holds 12 oz by weight.
If I knew how much 1 fluid oz of freon 134a weighs then
I could weigh the can to see how much freon I have put in the system.
But I could be overlooking something.
I want to charge a copper tube with 50% by volume of freon 134a.
I know the volume of the tube is 15.9 cubic inches but I only have a pressure gage.
The Freon can contains 12 oz by weight and I have no idea how much to add to the tube or how to measure it accurately.
This is not for an air...
Thanks for all the replies.
I have downloaded the Parker handbook and think I've got it figured out.
The bore size should be .312 with a gland depth of .050.
Pud,
"Note that the ether used in model diesel engine fuels is very aggressive with any standard O ring material (eg Viton, nbr, etc, etc.)"
This is not a contra piston. It uses a compression plug and Viton o-ring and I don't know how ether affects it.
But it's worth looking into.
Thanks.
Timelord,
I studied the Parker catalog but while it helped me decide on the proper grove for the ID I could not find anything to tell me the correct size for the bore.
This is a static seal, but it does have limited rotation if the compression screw is adjusted to raise or lower the...
The O-ring is AS568a -008.
This is a nominal size 3/16" ID x 5/16 OD" x 1/16" wide.
For a shaft .311" I decided on a gland grove of .0625" depth x .070" wide.
Tolerance on the shaft is +.000 / -.002.
The shaft is mild steel. And the application is a compression screw running in 6061...
