What did you use or do you recommend for air line in a shop?

[Paul]

There is a green colored PVC that is the only! PVC allowed for airline. If copper is used it requires a special solder. I have seen regular sch. 80 PVC blow apart.

Any Idea on what the special solder is?

 

[Paul]

95% Tin and 5% Antimony.

Paul;

Can you tell me more about the requirement of the special solder?

I put the flexible copper system in my shop about 6 years ago and knew nothing about needing a special solder, so I just used what I had on hand----no idea its make up. Since I have an out let about every 15' around a 40X60' shop, there are lots of 'Ts' and fittings soldered in.

What consequences am I likely to come up against??



Thanks

Vaughn

Looking at the chart again it seems that if you are running lower temps or lower press. you should have nothing to worry about.



50-50 tin and lead solder used on 1/4' to 1' copper tubing.

100deg 200 psi

150 " 150"

200 " 100 "



95-5 tin and antimony

100 deg. 500psi

150 " 400 "

200 " 300"



over 1'' the press. ratings drop.

Thanks Paul,

I am running 3/4 inch copper at 125 psi, so I'll not worry.
