Machined from acetal (polyoxymethylene), this fitting accepts 5\/16-inch OD tubing and threads into a 1\/4-inch NPTF port. It is rated to 300 psi maximum working pressure and handles temperatures from -20 degrees F to 180 degrees F. The push-to-connect design allows tubing to seat without additional tools, making it a practical choice for plumbing technicians and HVAC service professionals working in tight or hard-to-reach spaces.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for residential and light commercial fluid distribution and pneumatic control applications. Typical installations include condensate drain lines, low-pressure air lines, and control system tubing runs where a threaded port must transition to push-connect tubing. The NPTF thread form provides a pressure-tight mechanical seal without relying solely on thread sealant. The tan acetal construction resists corrosion and many common system fluids encountered in HVAC and plumbing service work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect design accepts 5\/16-inch OD tubing without tools\u003c\/li\u003e\n\u003cli\u003e1\/4-inch NPTF male thread for pressure-tight port connections\u003c\/li\u003e\n\u003cli\u003e300 psi maximum working pressure rating\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -20 degrees F to 180 degrees F\u003c\/li\u003e\n\u003cli\u003eAcetal (polyoxymethylene) construction resists corrosion and common system fluids\u003c\/li\u003e\n\u003cli\u003eTan color for easy visual identification in multi-line installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style push-to-connect adapter compatible with 5\/16-inch OD tubing and 1\/4-inch NPTF threaded ports in low-pressure fluid and pneumatic systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers, HVAC technicians, or qualified mechanics working on fluid or pneumatic systems. De-pressurize and isolate the system before removing or installing any fittings. Ensure tubing is cut cleanly and squarely, with no burrs, before inserting into the push-connect fitting to achieve a proper seal. NPTF threads are self-sealing by design, but consult applicable system codes and manufacturer guidance regarding the use of thread sealant compounds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inches\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: 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 180 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -20 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Acetal (Polyoxymethylene)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Tan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: A5TMC4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541468545330,"sku":"A5TMC4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36fece443602656bd476ae2d1b569624.jpg?v=1785877034","url":"https:\/\/voomisupply.com\/products\/parker-a5tmc4-tube-stem-adapter-5-16-od-1-4-nptf-300-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
