<VV> NEW TYPE SHOP AIR PLUMBING

[Garth Stapon]

In industrial gas, K grade copper or 300 series stainless are preferred.

Not only will stell rust, it is normally put together wwith threaded joints which tend to be leak prone over time.

Brazed cooper stands up well and will not leak anytime soon.
