It features a 1\/8-27 NPTF thread and is rated for a maximum working pressure of 150 psi and a temperature range of 0 to 150 degrees F. The fitting is manufactured from brass, making it well suited for air, water, and compatible fluid service lines. Licensed plumbers, HVAC technicians, and mechanical contractors use this fitting when connecting compression tubing to threaded pipe ends in both installation and service applications.\u003c\/p\u003e\u003cp\u003eThis fitting is used in residential and light commercial plumbing, HVAC, and pneumatic line applications where a reliable tube-to-pipe transition is required. The double end shutoff design allows flow control at the fitting itself, which is useful in service or repair scenarios where full system shutdown is not practical. The 1\/8-27 NPTF thread provides a pressure-tight mechanical seal without the need for additional sealant tape on the threaded end, though shop practice and applicable codes should guide final sealing decisions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass construction for corrosion resistance in air, water, and compatible fluid lines\u003c\/li\u003e\n\u003cli\u003e1\/8-27 NPTF thread standard ensures a pressure-tight threaded connection\u003c\/li\u003e\n\u003cli\u003eRated to 150 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of 0 to 150 degrees F\u003c\/li\u003e\n\u003cli\u003eDouble end shutoff design allows localized flow isolation\u003c\/li\u003e\n\u003cli\u003eTube-to-pipe end configuration for transitioning between compression tubing and threaded pipe\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style compression fitting for tube-to-pipe transitions in plumbing, HVAC, and pneumatic systems using 1\/8-27 NPTF threaded pipe connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified mechanical technician. Depressurize and drain the system completely before removing or installing any fittings. Follow applicable IPC and local plumbing code requirements for thread sealant use on NPTF connections.
