Constructed from brass, it connects a 1\/2-inch OD tube to a 1\/4-inch NPTF male thread using a tool-free push-to-connect tube port on each end. The fitting carries a maximum working pressure rating of 250 psi and is rated for temperatures from -40 degrees F to 200 degrees F. The nitrile O-ring sealing element ensures a reliable, leak-resistant connection under continuous vibration and pressure cycling typical of heavy-duty brake line service. Licensed technicians and fleet mechanics working on DOT-regulated air brake systems will find this fitting meets applicable federal and SAE standards.\u003c\/p\u003e\u003cp\u003eThis fitting is classified as a DOT air brake fitting, conforming to D.O.T. FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844. It is suited for use in commercial vehicle air brake lines, pneumatic control circuits, and related tube routing applications where a 90-degree change of direction is required between a 1\/2-inch OD tube and a 1\/4-inch male NPTF port. The rigid elbow orientation keeps the tube path fixed and reduces strain on adjacent fittings in confined plumbing runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect tube ports accept 1\/2-inch OD tubing without tools for fast assembly\u003c\/li\u003e\n\u003cli\u003eRigid 90-degree elbow geometry directs tube runs cleanly in tight or structured plumbing layouts\u003c\/li\u003e\n\u003cli\u003eBrass construction provides corrosion resistance and durability in brake line environments\u003c\/li\u003e\n\u003cli\u003eNitrile O-ring sealing material maintains a leak-free seal across the full operating temperature range\u003c\/li\u003e\n\u003cli\u003eRated to 250 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eMeets D.O.T.

Depressurize and drain the air system completely before removing or installing any brake line fitting. Inspect the tube end for squareness and burrs before inserting into the push-to-connect port, and verify the tube is fully seated before returning the system to service. Thread engagement into the NPTF port should follow standard NPTF hand-tight-plus-turns practice using appropriate thread sealant compatible with air 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: 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 Operating Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 200 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eO-Ring Material\u003c\/strong\u003e: Nitrile\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: D.O.T.
