This fitting accepts 3\/8 inch outside diameter tubing and features a 1\/4 inch NPTF threaded end for secure, leak-resistant attachment to mating ports. Constructed from Kynar (PVDF), it offers strong resistance to corrosive chemicals and elevated pressures. The FKM o-ring provides a reliable seal across a wide range of media. Rated to 250 psi and capable of handling a vacuum rating of 28 in-Hg, it suits demanding service environments where both pressure and vacuum conditions may occur. Installation requires no tools on the tube-insertion side, reducing labor time in the field.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for residential and light commercial applications involving chemical feed lines, water treatment systems, pool and spa plumbing, and HVAC condensate or fluid transfer lines. The Kynar construction makes it appropriate for use with mildly aggressive fluids where standard brass or nylon fittings would degrade. It is installed by plumbers, HVAC technicians, and pool service professionals wherever a push-to-connect tube port must transition to an NPTF-threaded port on a valve, manifold, or equipment panel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design on tube side — no tools or ferrules required for tube insertion\u003c\/li\u003e\n  \u003cli\u003eKynar (PVDF) body provides chemical resistance for corrosive fluid service\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPTF threaded end for positive, pressure-rated thread engagement\u003c\/li\u003e\n  \u003cli\u003eFKM o-ring seal suitable for a broad range of fluid media\u003c\/li\u003e\n  \u003cli\u003eRated to 250 psi working pressure\u003c\/li\u003e\n  \u003cli\u003eVacuum-rated to 28 in-Hg for low-pressure and suction-side applications\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 3\/8 inch OD tubing with a 1\/4 inch NPTF threaded port interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or qualified HVAC and pool service technicians. Shut off system pressure and bleed the line before removing any existing fitting. Ensure the mating NPTF port is clean and free of debris before threading the fitting; apply thread sealant per the system manufacturer recommendation and applicable plumbing code. Tube insertion requires that the tube end be cut square and deburred before pushing fully into the collet to achieve a proper seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Inside Diameter\u003c\/strong\u003e: 3\/8 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: 250 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVacuum Rating\u003c\/strong\u003e: 28 in-Hg\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Kynar (PVDF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eO-Ring Material\u003c\/strong\u003e: FKM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: FB6TMC4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541270200626,"sku":"FB6TMC4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e520afac064eeb03878bff90c10425d6_8d246f5d-d495-4118-be07-f52493257b50.jpg?v=1785871183","url":"https:\/\/voomisupply.com\/products\/parker-fb6tmc4-tube-stem-adapter-3-8-in-od-kynar-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
