An envelope of 11“ x 7“ is recommended. For 1-3/8“ couplings, a minimum of 4.4” is required between couplings (down to 3.3“ for 1/4“ couplings). A minimum of 2.3“ from the back wall surface is required. You need 2.5“ between couplings for jaws if the tool is coming up from below the fittings to press. …

The ends of the fittings should be no closer than 1/2 inch apart.
Brazing tubing after a fitting has been installed should be avoided at all costs. Minimum brazing distances below apply to pre-brazed tube sections as well. If field brazing, conventional precautions should be taken to ensure fitting remains cool. Minimum Distance From RLS Fitting To Braze 1/4 to 1/2 Tube Diameter = 5 in / 127 …

We know that not all copper tubing is the same, but we have tested RLS with most copper tube manufacturers with no issues. The tolerance for each tube to ensure a leak-free joint is defined by ASTM B280, B88 or B1003.
We do not have a specific product designed to press over this type of flared tubing. However, if there is at least 3 inches of straight copper tubing after the flared end is removed, and it is accessible with the jaws, we suggest that you cut the flared end off and press directly to the …

Use the depth gauge provided or the Minimum Insertion Depth guidelines below to determine the correct insertion depth. Mark the tubing with a permanent marker to indicate proper insertion depth on every tube. Minimum Insertion Depth 1/4, 5/16, 3/8 Fittings = 1 in / 25.4 mm 1/2, 5/8, 3/4, 7/8, 1, 1-1/8 Fittings = 1-1/4 …

If the flare of the fitting tends to be a problem, you can smooth the transition over the fitting by adding duct or electrical tape around the flared edge of the fitting to the tube.
A deep scratch is defined as one that can be felt with your fingernail. To remove minor scratches try using a new piece of Scotch Brite abrasive pad (maroon color) or 400 grit sandpaper. Alternatively, 180 grit sandpaper/cloth can be used for 15-20 seconds to remove a deep scratch.
Skipping installation instructions 4 through 8 will cause the tube to leak. It is very important to use the scouring pad and deburring tool. Refrigerant gas running at high pressure is more likely to leak than water at a much lower pressure, therefore, following the tube preparation instructions is critical.
