It accepts 3\/8 inch OD tubing and terminates in a 1\/4 inch NPTF thread for a pressure-tight seal without sealant tape when properly mated. The body is molded from polyoxymethylene (POM), a rigid acetal resin well suited to fluid and pneumatic systems where chemical resistance and dimensional stability matter. Rated to 300 psi, this fitting is sized for the light pneumatic and fluid-control plumbing common in HVAC, refrigeration controls, and instrumentation panels. Installation requires no tools on the tube side — tubing is inserted and locked mechanically.\u003c\/p\u003e\u003cp\u003eThis adapter is used in residential and light commercial applications where push-to-connect convenience is needed at a threaded port entry point. Typical scenarios include connecting small-bore tubing to valve bodies, manifolds, or instrumentation ports threaded 1\/4 inch NPTF. The tan POM construction is appropriate for compressed air, water, and many non-aggressive fluid lines. Plumbers, HVAC technicians, and controls installers use these fittings when routing 3\/8 inch OD tubing to threaded equipment ports in tight or frequently serviced locations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect on the tube side — no tools or ferrules required for tube insertion\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPTF thread provides a dry-seal, pressure-tight threaded connection\u003c\/li\u003e\n\u003cli\u003eRated to 300 psi for use in pneumatic and fluid control systems\u003c\/li\u003e\n\u003cli\u003ePolyoxymethylene (POM) body offers high rigidity and resistance to fuels and solvents\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.05 pounds — suitable for panel and manifold installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style push-to-connect adapter for systems using 3\/8 inch OD tubing terminating at a 1\/4 inch NPTF threaded port in pneumatic, HVAC control, or fluid-handling assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eShut off and depressurize the system completely before removing or installing any push-to-connect fittings. Inspect the tubing end for squareness and burrs before insertion — a clean, square cut ensures proper seating and seal engagement. NPTF threads are designed to seal on thread interference; inspect the mating port for damage before assembly. This fitting is installed by plumbers, HVAC technicians, and instrumentation technicians working under applicable mechanical codes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyoxymethylene (POM)\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\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: A6TMC4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541945712946,"sku":"A6TMC4","price":23.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a7b24d36ae5c2c0af6bf22999d59a6f.jpg?v=1785888174","url":"https:\/\/voomisupply.com\/products\/parker-a6tmc4-tube-stem-adapter-3-8-in-od-1-4-in-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
