It joins a 1\/2-inch push-to-connect port to a 3\/8-inch male NPT port, allowing quick, tool-free tube insertion on one end and a threaded port connection on the other. The composite body construction keeps weight low while maintaining a rated working pressure of 145 psi across a wide temperature range of -40 to 140 degrees F. This fitting is a standard choice for air brake and pneumatic control plumbing where D.O.T. compliance is required.\u003c\/p\u003e\n\u003cp\u003eThis connector is used in air brake system plumbing, pneumatic chassis lines, and compressed-air control circuits on commercial trucks, trailers, and heavy equipment. It suits new installations and replacement work where a push-to-connect-to-NPT transition is needed. The 3\/8-18 NPT thread mates to standard port bosses on valves, tanks, and manifolds. Installation is handled by fleet technicians, diesel mechanics, and licensed air brake service technicians working under D.O.T. guidelines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eD.O.T.-compliant composite body rated for air brake and pneumatic service\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch push-to-connect inlet accepts tubing without additional tools\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch male NPT outlet with 3\/8-18 thread for standard port connections\u003c\/li\u003e\n  \u003cli\u003e145 psi working pressure rating\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 to 140 degrees F suits under-hood and chassis environments\u003c\/li\u003e\n  \u003cli\u003eCompact profile at approximately 1.2 inches height and 0.9 inches length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a D.O.T.-compliant OEM-style replacement or new-installation fitting for 1\/2-inch push-to-connect pneumatic tubing systems transitioning to 3\/8-inch male NPT ports on commercial vehicles and trailers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician familiar with D.O.T. air brake regulations and federal motor vehicle safety standards. Depressurize the air system completely before removing or installing any pneumatic fitting. Ensure the NPT threads are sealed with an appropriate thread sealant compatible with air service, and do not over-tighten the threaded connection. Verify that the push-to-connect tubing is cut clean and square before insertion to ensure a proper seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Push-to-Connect\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Male NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 145 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -40 to 140 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.85 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.085 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 680806C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67949662535986,"sku":"680806C","price":17.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5abeed02b4fb462763a99f9a937563d5_142bb16b-df65-43d4-948d-99d1011fcd70.jpg?v=1791697308","url":"https:\/\/voomisupply.com\/products\/midland-industries-680806c-dot-male-connector-ptc-x-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
