It accepts 1\/2 inch OD tubing on each tube end and threads into a 1\/4 inch NPTF port. The fitting is rated to 250 psi maximum working pressure and handles temperatures from -40 degrees F to 200 degrees F, making it suitable for demanding mobile and stationary compressed-air applications. It meets DOT FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards. A nitrile o-ring provides a reliable, vibration-resistant seal. Licensed HVAC techs, plumbers, and fleet mechanics working on air brake and general-purpose pneumatic systems are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis fitting is rated as a DOT air brake fitting and is appropriate for general-purpose pneumatic lines in commercial vehicles, industrial equipment, and compressed-air distribution systems. Its push-to-connect design allows fast, tool-free tube insertion while the NPTF thread end seals into a tapped port without additional sealant when properly torqued. The 7\/8 inch hex size accommodates standard open-end or box wrenches for the threaded connection side.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design for quick, secure 1\/2 inch OD tube installation\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPTF male thread end for leak-resistant port connection\u003c\/li\u003e\n  \u003cli\u003e250 psi maximum working pressure for compressed-air and air brake service\u003c\/li\u003e\n  \u003cli\u003eRated from -40 degrees F to 200 degrees F for mobile and industrial environments\u003c\/li\u003e\n  \u003cli\u003eNitrile o-ring seal for reliable performance in general-purpose pneumatic systems\u003c\/li\u003e\n  \u003cli\u003eCompliant with DOT FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for general-purpose pneumatic and DOT air brake plumbing applications using 1\/2 inch OD tubing and 1\/4 inch NPTF ported components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed mechanics, plumbers, or pneumatic system technicians. Depressurize and bleed down the air system completely before removing or installing any fittings. Insert tubing fully into the push-to-connect end until it bottoms out; confirm tube retention before re-pressurizing. Tighten the NPTF thread end with a properly sized wrench to achieve a thread-interference seal, and inspect for leaks at operating pressure before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Tube x MNPT x Tube x Male (Push-To-Connect)\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 NPTF\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\u003eMaximum Working Temperature\u003c\/strong\u003e: 200 degrees F\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\u003eOverall Length\u003c\/strong\u003e: 1.49 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DOT FMVSS 571.106, SAE J2494, SAE J2494-3, SAE J844\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: DOT Air Brake, General Purpose Pneumatic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 68PTC-8-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541761556786,"sku":"68PTC-8-4","price":28.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6931f17d40cd9018012b453d45f6d8e8_ee43d047-8f8d-416a-94cf-915bba439fd7.jpg?v=1785884253","url":"https:\/\/voomisupply.com\/products\/parker-68ptc-8-4-push-to-connect-male-connector-1-2-od","provider":"Voomi Supply","version":"1.0","type":"link"}
