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 type letter indicating wall thickness. Beside above, what is copper fitting? Copper fitting is connected to a copper pipe using soldering method.
Full Answer
What does ACR stand for in copper?
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. Tube in the hard temper condition is usually joined by soldering or ...
What are the advantages of copper pipe fittings over plastic?
The top 5 reasons
- Press fittings save time and money. With press fittings, connections can be made in a fraction of the time that it takes to weld or solder pipe. ...
- Press fitting connections are secure. Press tool operations vary by brand, but one thing that is consistent is the strength of connections. ...
- Jobsite safety is improved with press fittings. ...
What is the largest copper pipe fitting?
There are three series (plus DWV ):
- K, having the heaviest walls, typically used for underground burial.
- L, used for most purposes.
- M, with the lightest walls, used for drainage and other low-pressure applications. (Some plumbing codes do not permit M.)
How to use solderless copper pipe fittings?
- Long lasting – properly pressed fittings last the life of the pipe
- Reliable – correctly pressed fittings withstand standard pipe temperatures and pressures
- Use the right tools – excessive pressing can result in squared, less reliable connections
What does ACR mean on copper fittings?
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 is Type L ACR copper?
ACR Type L copper tubing is typically used with wrot copper fittings called by the OD and not the NOM sizes. ASTM specifications are C12200, ASTM B-280 This Pipe Is Called And Ordered By The OD With The Same Wall Thickness As Type L. MADE IN USA 38ACR20.
Is ACR copper Type L or K?
Type L copper pipes are typically used for residential water systems. Copper, used for refrigeration, is designated as ACR copper.
How is ACR copper sizes?
Available sizes ranging from 1/8” to 8-1/8” in outside diameter Streamline® Nitrogenized® ACR Copper Tube is pressurized with nitrogen to provide maximum protection against the formation of harmful oxides normally formed during brazing operations.

Is ACR pipe ID or OD?
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.
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.
Can you use ACR copper for gas?
Types K and L copper tube (ASTM B 88) and ACR tube (ASTM B 280), up to and including 1-inch outside diameter, have been used in fuel gas systems for many years.
In what temper is ACR copper tube available?
ACR Straight Tube is usually supplied in the hard and half hard temper, annealed temper is also available if requested.
