RectorSeal, Houston, a leading manufacturer of quality HVAC/R products, 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.

Other Quick Connect features include:

  • Double O-rings’ leak-resistant elastomeric materials are specifically designed and third-party certified under UL 157 test standard for minimal shrinkage (less than one percent) and swelling in R-410A/POE oil refrigeration systems;
  •  Service valves (1/4, 3/8, 1/2 and 5/8-inch) are available on an OEM basis;
  • Reducers and 90° elbow reducers step down from 5/8 to 1/2-inch, 1/2 to 3/8-inch, and 3/8 to 1/4-inch line sizes;

  • Separate depth marking and release clip tools are available for each of the 3/4 and 7/8-inch diameter fittings.
