Constructed from POM (polyoxymethylene), the fitting delivers a rated working pressure of 300 psi. The push-to-connect mechanism allows fast, tool-free tube insertion while the threaded end seals directly into a female NPTF port. These fittings are commonly installed by HVAC technicians, plumbers, and industrial service professionals in pneumatic control lines, instrument tubing runs, and fluid-handling assemblies where a reliable tube-to-thread transition is required.\u003c\/p\u003e\n\u003cp\u003eThe A4TMC2 is suited for residential and light commercial applications involving pneumatic controls, refrigeration sensing lines, or low-pressure fluid circuits. The 1\/8 inch NPTF thread provides a pressure-tight dry seal without the need for additional sealant tape in many installations, though shop practice and system requirements should guide that decision. The 1\/4 inch OD tube size is a common dimension in HVAC control tubing and instrumentation lines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design allows fast, tool-free tube insertion and secure retention\u003c\/li\u003e\n  \u003cli\u003ePOM (polyoxymethylene) construction resists moisture and common refrigeration system chemicals\u003c\/li\u003e\n  \u003cli\u003e300 psi rated working pressure suitable for pneumatic and low-pressure fluid applications\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch NPTF thread provides a dry-seal pressure-tight connection\u003c\/li\u003e\n  \u003cli\u003eTan color for quick visual identification in multi-fitting assemblies\u003c\/li\u003e\n  \u003cli\u003eCompact form factor fits into tight equipment cabinets and control panels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect tube stem adapter for systems using 1\/4 inch OD tubing and 1\/8 inch NPTF threaded ports in pneumatic, HVAC control, and low-pressure fluid-handling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDepressurize and isolate the system completely before removing or installing any tube fittings. Verify the tube end is cut square and free of burrs before inserting into the push-to-connect collet. Thread the NPTF end into the receiving port by hand first to confirm thread engagement, then tighten with an appropriate wrench to avoid over-torquing the POM body. Follow applicable plumbing and pneumatic system codes for pressure testing after installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: POM (Polyoxymethylene)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 psi\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: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\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: A4TMC2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538824069426,"sku":"A4TMC2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdf6f777259ff67826b7aeebeb3884be.jpg?v=1785827598","url":"https:\/\/voomisupply.com\/products\/parker-a4tmc2-push-to-connect-tube-stem-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
