Built from polyoxymethylene (POM), a rigid acetal-based thermoplastic, this fitting delivers reliable performance in low-to-medium pressure applications up to 300 psi. The tan-colored body resists moisture and common chemicals, making it well-suited for compressed air, instrumentation, and light fluid transfer lines. HVAC technicians, plumbers, and instrumentation contractors install this fitting where a fast tube connection to a threaded male port is needed without soldering, flaring, or compression tooling.\u003c\/p\u003e\u003cp\u003eThis adapter is used in residential and light commercial applications where 5\/16 inch OD tubing must terminate at a 1\/8 inch NPTF threaded port. Typical install scenarios include refrigeration instrumentation lines, pneumatic control tubing, and low-pressure fluid transfer systems. The NPTF thread form provides a pressure-tight mechanical seal without requiring additional sealant on the threads, though practices vary by application and local code.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect design allows fast, tool-free tube insertion and release\u003c\/li\u003e\n\u003cli\u003eRated to 300 psi for compatibility with compressed air and low-pressure fluid systems\u003c\/li\u003e\n\u003cli\u003ePolyoxymethylene (POM) body resists moisture, oils, and many common chemicals\u003c\/li\u003e\n\u003cli\u003e1\/8 inch NPTF thread creates a pressure-tight seal at the port connection\u003c\/li\u003e\n\u003cli\u003eAccepts 5\/16 inch OD tubing without compression rings or ferrules\u003c\/li\u003e\n\u003cli\u003eCompact, lightweight form factor at 0.05 pounds per piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style push-to-connect fitting for pneumatic, instrumentation, and light fluid transfer systems using 5\/16 inch OD tubing and 1\/8 inch NPTF threaded ports.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified HVAC technicians, plumbers, or instrumentation mechanics following applicable codes. Depressurize and isolate the system completely before removing or installing any fittings. Insert tubing fully into the push-to-connect body until it seats to ensure a leak-free connection; a partial insertion is the most common cause of leaks. Verify NPTF thread engagement is adequate and inspect for leaks at full system operating pressure before returning the system to service.\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\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\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: A5TMC2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540948877618,"sku":"A5TMC2","price":19.64,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d963ee8cdc3eea6b4ef5f925dbcb669_e3c0f464-7736-4775-9291-444c150ebdda.jpg?v=1785866319","url":"https:\/\/voomisupply.com\/products\/parker-a5tmc2-tube-stem-adapter-5-16-in-od-1-8-in-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
