Compressed Air Piping

For copper installations there are "Sharkbite" fittings so no soldering.
"SharkBite fittings are certified to 200 PSI and 200°F (93°C)"

Regardless of pipe used, proper mounting and reinforcement is required along runs and especially at fittings and ends to avoid stress failures.

I like Gary in AZ's link, really answers the questions.

For the price, the RapidAir MaxLine kit would be my direction, seems very complete and easy install.
