Constructed from brass, it connects a 1\/2-inch OD tube on each end to a 1\/4-inch male NPT port, with a swivel design that simplifies alignment during installation. Rated to 250 psi maximum working pressure, it carries D.O.T. FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 certifications, making it compliant for air brake service on commercial vehicles. Licensed technicians and fleet mechanics working on D.O.T.-regulated air brake systems are the primary installers of this fitting.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for truck, trailer, and commercial vehicle air brake plumbing where a 45-degree directional change is needed between a tube run and a threaded port. Its push-to-connect ends allow fast, tool-free tube insertion while the swivel male NPT thread enables the fitting to be torqued into the mating port without twisting the tube. Operating temperature range spans from -40 degrees F to 200 degrees F, supporting year-round service across a wide range of climates and engine-bay environments. The nitrile O-ring seals are compatible with the moisture and oil contamination common in vehicle air brake circuits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect ends accept 1\/2-inch OD tubing without tools or ferrules\u003c\/li\u003e\n\u003cli\u003eSwivel 45-degree male elbow body reduces stress on tube routing at angled connections\u003c\/li\u003e\n\u003cli\u003e1\/4-inch male NPT thread for direct installation into standard tapped ports\u003c\/li\u003e\n\u003cli\u003eBrass construction resists corrosion in wet and oily pneumatic environments\u003c\/li\u003e\n\u003cli\u003e250 psi maximum working pressure rated for air brake service\u003c\/li\u003e\n\u003cli\u003eD.O.T.

This fitting is installed by qualified truck and fleet technicians familiar with D.O.T. air brake regulations and SAE J844 plumbing requirements. Thread the male NPT end into the port using an appropriate wrench and thread sealant compatible with air brake service; do not overtighten. Insert tubing straight into the push-to-connect end until it seats fully, and verify retention by pulling back lightly on the tube before returning the system to pressure.\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\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/2 inch\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\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\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\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\u003eStandards\u003c\/strong\u003e: D.O.T.
