RectorSeal® PRO-Fit™ Product Line Adds Quick Connect Refrigerant Line Fittings

Refrigerant lines are push fit into PRO-Fit™ Quick Connect fittings within seconds without brazing, flaring or expensive crimping connection tools.

Thursday, Jan. 30, 2020 - RectorSeal®, Houston, a leading manufacturer of quality HVAC/R products, and part of the CSW Industrials, Inc. [NASDAQ:CSWI] group of companies, has added the Quick Connect push-fit, flame-free, refrigerant line brass fitting system to its PRO-Fit™ tools and accessories product line for the North America and Australia markets. Quick Connect is the new generation of refrigeration pipefitting designed for ductless mini-split and ducted unitary, single-family residential air conditioning systems. It’s the HVAC/R industry’s only major refrigerant fitting system that doesn’t require flaring, brazing or expensive crimping connection tools.

After cutting, deburring and marking for proper depth, the refrigerant line installation requires just a few seconds to push into the fitting until the depth marking appears in the sight glass. Each Quick Connect fitting port consists of a patented factory-assembled tight-fitting double O-ring, protector, grip ring and an endcap–none of which needs to be addressed by the installer.

No special tools are required except for a reusable and inexpensive support kit that is sold separately, consisting of a pipe depth marking tool and five sizes of horseshoe-shaped release clips that disengage a connection within seconds.

Quick Connect comes in five fitting types–union, 90° elbow, reducer, 90°elbow reducer and socket–and the four most common lineset diameters of: 1/4-inch (6-mm), 3/8-inch (9-mm), 1/2-inch (12-mm), and 5/8-inch (16-mm). Quick Connect also includes 3/4-inch (19-mm) and 7/8-inch (22-mm) sizes, but only for the union and the 90° elbow fittings.

Quick Connect is UL certified and third-party tested under UL 157, UL 203, UL 250 and UL 1963. Passed test conditions include long-term helium leak, vibration, burst pressure, tensile strength, reusability, salt spray, fatigue, chemical compatibility and six other reliability tests. Quick Connect fittings accommodate system pressures up to 870-PSI and are designed for both HCFC and HFC refrigerants–R-22, R-410A, R-744, R-134a, R-407A, and R-507.
