The body is molded from polyoxymethylene (POM), a rigid engineering thermoplastic known for chemical resistance and dimensional stability. Rated to 250 psi, this fitting is suited for pneumatic lines, fluid transfer systems, and instrumentation tubing where a reliable push-in connection to a tapered pipe thread port is required. Licensed HVAC technicians, plumbers, and industrial service technicians commonly install this type of fitting during system assembly or repair.\u003c\/p\u003e\n\u003cp\u003eThis adapter is appropriate for light-duty pneumatic and fluid applications in residential and commercial settings. The push-to-connect design allows tubing to seat and lock without additional tools, making it practical for tight spaces or quick-turnaround service calls. The NPTF thread provides a dry-seal mechanical connection that does not rely solely on thread sealant. Typical use cases include instrument air lines, control tubing, and low-pressure fluid distribution.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design allows tool-free tube insertion and secure locking\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch OD tube connection with 1\/4 inch NPTF male thread\u003c\/li\u003e\n  \u003cli\u003eRated to 250 psi working pressure\u003c\/li\u003e\n  \u003cli\u003ePOM (polyoxymethylene) construction offers chemical resistance and rigidity\u003c\/li\u003e\n  \u003cli\u003eTan color body for visual identification in multi-line installations\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight form at 0.07 pounds for installations in confined spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install fitting for systems using 1\/2 inch OD tubing with 1\/4 inch NPTF threaded ports in pneumatic or fluid distribution applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified tradespeople familiar with push-to-connect pneumatic or fluid fittings. De-pressurize and isolate the system fully before removing any existing fitting or inserting the new adapter. Ensure the mating NPTF port is clean and free of debris before threading in the adapter; apply thread sealant per the system manufacturer and local code requirements. Do not exceed the 250 psi rated working pressure, and verify tubing OD is within tolerance before seating to ensure the collet engages correctly.\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\/2 inch\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\u003eMaximum Working Pressure\u003c\/strong\u003e: 250 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: POM (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: 0.07 pounds\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: A8TMC4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541844754738,"sku":"A8TMC4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a42c574db9c03d8e21d77c5253d39d3.jpg?v=1785886593","url":"https:\/\/voomisupply.com\/products\/parker-a8tmc4-push-to-connect-tube-stem-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
