Quick facts
The A.C.R. copper long-radius 90° elbow is used to change direction on a refrigerant line: the copper tube slips into each of its two female ends (C × C), then the joint is brazed. Its curve, wider than a short-radius elbow’s, lets the refrigerant flow with less turbulence.
An elbow for heat pump and air conditioning lines
We use it on the suction and liquid lines of wall-mounted heat pumps, central heat pumps and multi-zone systems, along a wall, under a ceiling or in a service chase. It is also used to extend or repair an existing line.
Eleven diameters, from 1/4 in to 2-5/8 in
The elbow is available for tubes of 1/4 in, 3/8 in, 1/2 in, 5/8 in, 3/4 in, 7/8 in, 1-1/8 in, 1-3/8 in, 1-5/8 in, 2-1/8 in and 2-5/8 in outside diameter. Each size has its own AirGreen code, shown under the title when you select it.
Short radius, long radius or street?
- Long radius: less pressure drop, the right choice on a long suction line.
- Short radius: more compact, for tight spots.
- Street (male × female): one end goes directly into another fitting and saves a coupling.
Good brazing practice
Cut the tube square, deburr it and clean it before fitting. Braze under a light flow of dry nitrogen to keep the inside of the joint clean. Work on a refrigerant circuit is reserved for a qualified refrigeration technician.

A 90° elbow that keeps refrigerant moving
Wherever a refrigerant line has to turn, the long radius keeps the flow smooth.

What to know before installing
- The size is the outside diameter of the copper tube it connects.
- Cut the tube square, deburr it and clean it before fitting.
- Braze with a light flow of dry nitrogen to keep oxide out of the joint.
- Work on a refrigerant circuit is reserved for a qualified refrigeration technician.

Frequently asked questions
What is the difference between a short-radius and a long-radius elbow?
The long radius has a wider bend: the refrigerant turns with less turbulence and less pressure drop. The short radius takes less room in a tight spot.
Is the size the tube or the fitting?
The outside diameter of the copper tube. A 5/8 in elbow takes a tube with a 5/8 in outside diameter.
How is it different from a street elbow?
A C × C elbow has two female ends. A street elbow has one male end that slides straight into another fitting, which saves a coupling.
Can you install it?
Yes. Our technicians run the refrigerant piping when they install your heat pump, everywhere in Greater Montréal.
