Constructed from brass, this fitting connects 1\/4 inch OD tubing on both run ports to a 1\/4 inch NPTF male thread port, allowing a branch takeoff without cutting the main run line. It carries a maximum working pressure rating of 250 psi and is rated for operating temperatures from -40 degrees F to 200 degrees F. An internal nitrile O-ring provides a reliable seal at the tube connection points. HVAC technicians, plumbers, and fleet maintenance professionals install this fitting where a DOT-compliant air brake or pneumatic line requires a tee connection.\u003c\/p\u003e\u003cp\u003eThis fitting is rated and marked as a D.O.T. air brake fitting, meeting FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards. It is appropriate for use in residential and commercial pneumatic systems, refrigeration line sets, and DOT-regulated air brake circuits on commercial vehicles where a brass push-to-connect tee is required. The push-to-connect design allows for tool-free tube insertion while maintaining a secure, pressure-rated seal in both stationary and mobile applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect design accepts 1\/4 inch OD tubing on both run ports for fast, tool-free installation\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPTF male thread branch port for secure threaded connections\u003c\/li\u003e\n\u003cli\u003eBrass body construction for corrosion resistance in pneumatic and air brake environments\u003c\/li\u003e\n\u003cli\u003eNitrile O-ring seals rated from -40 degrees F to 200 degrees F\u003c\/li\u003e\n\u003cli\u003e250 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eD.O.T. compliant — meets FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DOT-compliant push-to-connect replacement or new-installation fitting for pneumatic tubing systems using 1\/4 inch OD tube and 1\/4 inch NPTF threaded ports, including air brake circuits meeting SAE J844 and SAE J2494 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers, HVAC technicians, or qualified fleet maintenance mechanics. Before servicing any pneumatic or air brake line, fully depressurize the system and verify zero line pressure. Tube ends must be cut cleanly and squarely with a proper tubing cutter — do not use a saw — and deburred before insertion to ensure a proper O-ring seal. Verify that the NPTF thread engagement meets applicable torque and sealant requirements per shop standards and IFGC or DOT guidelines before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Tube x MNPT x Tube x Male (Push-To-Connect)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 250 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 200 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eO-Ring Material\u003c\/strong\u003e: Nitrile\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.79 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: D.O.T.
