QuickFitting announced the launch of HVAC/R Push-to-Connect refrigerant fittings for installation and maintenance of HVAC/R systems. Installers can connect refrigerant lines easily by pushing the fitting onto the pipe. A patented double O-ring and grip ring seal delivers a secure connection that withstands galling, vibration, pulsation and extreme temperature changes. The body is corrosion- and UV-resistant, while yellow protective caps keep debris out. They are designed for residential and commercial HVAC/R applications, and compatible with copper and coated aluminum line sets, HVAC/R units and unitary indoor coils. They are approved for use with industry-standard refrigerants, and are removable using the patented HVAC Slip Clip Release Tool.

 The instillation begins with cutting the tube at a straight angle and cleaning it. The next step involves deburring the inside and outside edges to achieve a smooth finish. The tube should be marked with the correct insertion depth before pushing the fitting onto the tube up to the marked line. To remove installed fittings, the system charge must first be isolated or removed to ensure safety. The Slip Clip is then slid onto the fitting end, and once properly aligned, the fitting can be pulled away from the pipe to release the connection.
