It connects 1\/4 inch OD tubing to a 1\/4 inch male NPT port, creating a fixed 45-degree directional change without additional fittings. Constructed from brass with a nitrile O-ring, it is rated for 250 psi maximum working pressure and handles temperatures from -40 degrees F to 200 degrees F. This fitting meets DOT FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards, making it a compliant choice for commercial vehicle air brake systems. Plumbers and fleet maintenance technicians working on DOT-regulated brake circuits use this fitting for reliable, leak-resistant connections.\u003c\/p\u003e\u003cp\u003eThe 179PTCNS-4-4 is used in DOT-regulated air brake plumbing on commercial trucks, trailers, and buses where a compact 45-degree directional transition is needed from a threaded NPT port to push-to-connect tubing. The push-to-connect design allows quick tube insertion and secure retention without threading or flaring the tube end. It is appropriate for both OEM assembly and field service replacement in pneumatic circuits operating within its rated pressure and temperature limits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect design accepts 1\/4 inch OD tube for tool-free tube insertion\u003c\/li\u003e\n\u003cli\u003e45-degree rigid male elbow configuration for directional routing in tight spaces\u003c\/li\u003e\n\u003cli\u003eBrass construction with nitrile O-ring for durability in pneumatic service\u003c\/li\u003e\n\u003cli\u003eRated to 250 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -40 degrees F to 200 degrees F\u003c\/li\u003e\n\u003cli\u003eCompliant with DOT FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DOT air brake systems and pneumatic circuits requiring a 1\/4 inch OD tube to 1\/4 inch male NPT connection with a 45-degree elbow orientation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with DOT air brake system regulations. Depressurize the air system completely before removing or installing any fittings. Ensure the tube end is cut cleanly and squarely and is free of burrs before inserting into the push-to-connect fitting. Verify the NPT threads are properly sealed with approved thread sealant and that the completed assembly is leak-tested before returning the vehicle to service.\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\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\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 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\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\u003eWeight\u003c\/strong\u003e: 0.07 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\u003eSpecial Classification\u003c\/strong\u003e: DOT Air Brake Fitting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 179PTCNS-4-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541295071538,"sku":"179PTCNS-4-4","price":43.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bc2a2d8eeae566612cd17dfefe1e537_a4ab75e8-f0b0-41af-b2fb-a1c938c1f0e1.jpg?v=1785871607","url":"https:\/\/voomisupply.com\/products\/parker-179ptcns-4-4-45-male-elbow-1-4-od-1-4-npt-brass-dot","provider":"Voomi Supply","version":"1.0","type":"link"}
