It provides a three-way connection with a 3\/8 inch tube OD inlet on the run, a 1\/4 inch male NPTF port, and a 1\/4 inch tube OD outlet, allowing a branch tap off an existing air line without interrupting the main flow path. The fitting is rated to 150 psi and handles temperatures from -40 to 200 degrees F. The 17\/32-24 thread specification meets NAB standards. Weighing approximately 0.13 pounds, this compact fitting suits tight chassis routing environments typical in heavy-duty air brake plumbing.\u003c\/p\u003e\u003cp\u003eThe 38124 is intended for use with SAE J844 Type A and Type B NT nylon tubing in DOT-compliant air brake circuits. Typical applications include tractor-trailer brake systems, bus air lines, and other commercial vehicle pneumatic plumbing where a reliable branch connection off a main air supply line is required. The brass construction resists corrosion in the moisture-laden air streams common to air brake reservoirs and supply circuits. This fitting is a standard service item stocked by fleet maintenance shops and brake system specialists.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThree-way run tee configuration: 3\/8 inch tube OD run through with 1\/4 inch branch connections\u003c\/li\u003e\n\u003cli\u003eRated to 150 psi working pressure for air brake circuit service\u003c\/li\u003e\n\u003cli\u003eTemperature range of -40 to 200 degrees F suits year-round commercial vehicle operation\u003c\/li\u003e\n\u003cli\u003e17\/32-24 NAB thread form for DOT air brake system compatibility\u003c\/li\u003e\n\u003cli\u003eBrass construction provides corrosion resistance in wet air environments\u003c\/li\u003e\n\u003cli\u003eCompatible with SAE J844 Type A and Type B NT nylon tubing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SAE J844 Type A and Type B NT nylon tubing in DOT air brake nylon tubing systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified brake system technician familiar with DOT air brake regulations and applicable FMVSS standards. Fully depressurize and drain the air brake system before removing or installing any fittings. Ensure nylon tubing is cut cleanly and squarely and seated fully into the fitting before pressurizing. Inspect for leaks at operating pressure before returning the vehicle to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection 1\u003c\/strong\u003e: 3\/8 inch Tube OD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection 2\u003c\/strong\u003e: 1\/4 inch Male NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection 3\u003c\/strong\u003e: 1\/4 inch Tube OD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread\u003c\/strong\u003e: 17\/32-24 NAB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -40 to 200 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.05 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Tubing\u003c\/strong\u003e: SAE J844 Type A and Type B NT Nylon Tubing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 38124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948834947378,"sku":"38124","price":34.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/793461dd9f0c1732a76836c4977ae9df_a562939c-5da4-4e09-b3f8-1a31751194de.jpg?v=1791674243","url":"https:\/\/voomisupply.com\/products\/midland-industries-38124-brass-run-tee-dot-air-brake-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
