Constructed from brass, this fitting accepts 5\/32 inch OD tubing on the push-to-connect ends and threads into a 1\/4 inch NPT male port. It is rated for a maximum working pressure of 250 psi and carries a D.O.T. Air Brake designation, making it suitable for use in air brake systems on commercial vehicles and heavy equipment. The nitrile O-ring provides a reliable seal across a wide service temperature range. Licensed technicians and fleet maintenance professionals typically install this type of fitting in pneumatic brake and air supply lines.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in applications requiring a fast, tool-free tube connection to an NPT-threaded male port. Common installation scenarios include air brake systems, pneumatic control lines, and compressed air distribution in both mobile and stationary equipment. Its D.O.T. Air Brake rating qualifies it for use in regulated commercial vehicle brake circuits. The brass construction makes it well suited to dry air, mild compressed gas, and compatible fluid services within its rated pressure and temperature limits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design accepts 5\/32 inch OD tubing without additional tools for tube insertion\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPT male thread end for direct port installation\u003c\/li\u003e\n  \u003cli\u003eRated to 250 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eD.O.T.

Depressurize the air system completely and verify zero line pressure before removing or installing any fitting. Ensure tubing is cut cleanly and squarely and that the tube OD is free of burrs or deformation before insertion into the push-to-connect port. Air brake system repairs on commercial vehicles must comply with applicable D.O.T. and FMCSA regulations governing brake system maintenance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\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\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\u003eSpecial Designation\u003c\/strong\u003e: D.O.T.
