Copper tube for air-conditioning and refrigeration field service (ACR) is designated by actual outside diameter. “Temper” describes the strength and hardness of the tube. In the piping trades, drawn temper tube is often referred to as “hard” tube and annealed as “soft” tube.

What does ACR mean on copper fittings?

The North American refrigeration industry uses copper pipe designated ACR (air conditioning and refrigeration field services) pipe and tubing, which is sized directly by its outside diameter (OD) and a typed letter indicating wall thickness.

What is ACR hard drawn copper?

ACR (Air Conditioning and Refrigeration) tubing is charged with nitrogen and sealed. Same as L thickness, it comes in both hard drawn tubing and “soft” rolls of 50′ and 100′. Soft tubing is annealed (heated and then allowed to cool) to make it flexible and easy to bend and flare.

What is Type ACR copper pipe used for?

Can you bend ACR copper?

It is possible to physically bend drawn general purpose (H58) tubing, but the result is not acceptable. Bending H58 is not recommended by the tubing manufactures. Only Soft Anneal (O60) or Light Drawn (H55) should be used when field bending ACR Type L or Type K copper tube.

Which pipe is best for gas lines?

CSST tubing, or corrugated stainless steel tubing, is good for installing gas appliances. These corrugated pipes can bend around corners reducing the number of joints and fittings. Easier to work with than steel pipe and weighs a lot less.

Can you refrigerate copper for gas?

copper is safe for LP, but not recommended for natural gas. due to “concerns over corrosion and flaking of copper tubing, copper is not allowed for use on natural gas work in some localities” (see reference) home depot says “Use M (red)-rated copper for indoor gas distribution”
