It connects 1\/2 inch tube OD to a 3\/8 inch male NPTF port using an 11\/16-20 thread. The fitting includes an RTS (Release Tool Service) mechanism, which allows the tubing to be released from the fitting without damaging the tube or the fitting body. Rated to 150 psi and suitable for temperatures ranging from -40 degrees F to 200 degrees F, this adapter is built for the pressure and thermal demands of commercial vehicle and industrial air brake circuits. Installation is handled by qualified mechanics and pneumatic system technicians.\u003c\/p\u003e\u003cp\u003eThis fitting is intended for use in air brake plumbing applications where SAE J844 Type A and Type B NT nylon tubing is specified. It is commonly installed in commercial truck, trailer, and heavy equipment air brake lines where a secure, push-to-connect tube-to-pipe transition is needed. The male NPTF thread provides a pressure-tight seal at the port connection without requiring additional sealant in most applications. It falls within the MAF AIR BRAKE product line under the NAB Male Adapters category.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRTS release mechanism allows safe, tool-assisted tube removal without fitting damage\u003c\/li\u003e\n\u003cli\u003e1\/2 inch tube OD to 3\/8 inch male NPTF configuration for tube-to-pipe transitions\u003c\/li\u003e\n\u003cli\u003eRated to 150 psi working pressure\u003c\/li\u003e\n\u003cli\u003eTemperature range of -40 degrees F to 200 degrees F suits outdoor and underhood environments\u003c\/li\u003e\n\u003cli\u003eCompatible with SAE J844 Type A and B NT nylon tubing\u003c\/li\u003e\n\u003cli\u003eBrass construction provides corrosion resistance in air brake service\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 air brake plumbing systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or pneumatic systems technician familiar with air brake regulations and DOT requirements. Depressurize the air brake system fully before disconnecting or installing any fittings. NPTF threads are designed to seal on the thread form itself, but inspect threads carefully before assembly to ensure a leak-free connection. Verify tubing is cut cleanly and squarely and fully seated before pressurizing the system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1\/2 inch Tube OD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Tube OD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 3\/8 inch Male NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Male NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread\u003c\/strong\u003e: 11\/16-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -40 degrees F to 200 degrees F\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 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: NT68-86VS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67952203235634,"sku":"NT68-86VS","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6116122f56230335d6a8450c3aa6eaa_084dc82c-5464-4d78-a497-38f9eeb24f47.jpg?v=1791749915","url":"https:\/\/voomisupply.com\/products\/midland-industries-nt68-86vs-air-brake-tube-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
