The captive sleeve design retains the compression sleeve on the fitting body, preventing loss during disassembly and simplifying reinstallation in tight spaces. Constructed from brass, this adapter handles a wide temperature range of -65 to 250 degrees F, making it suitable for fuel, refrigeration, and instrument tubing applications. Plumbers, HVAC technicians, and instrumentation professionals install this fitting where small-diameter tubing must terminate at a threaded male port.\u003c\/p\u003e\u003cp\u003eThis adapter is used in residential and light commercial applications involving small-bore tubing runs. Typical scenarios include connecting 3\/16 inch copper or compatible tubing to equipment manifolds, control valves, or instrument ports with 1\/4 inch NPTF female threads. Its compact profile fits in panel cutouts and equipment enclosures where clearance is limited. The NPTF thread form provides a pressure-tight mechanical seal without relying solely on thread sealant.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCaptive sleeve retains compression sleeve on body for easier handling during service\u003c\/li\u003e\n\u003cli\u003e3\/16 inch compression inlet connects to standard small-diameter tubing\u003c\/li\u003e\n\u003cli\u003e1\/4 inch male NPTF outlet for dry-seal threaded connections\u003c\/li\u003e\n\u003cli\u003eBrass construction resists corrosion in fuel, air, and refrigerant service\u003c\/li\u003e\n\u003cli\u003eRated from -65 to 250 degrees F for broad application compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for systems requiring a 3\/16 inch compression to 1\/4 inch male NPTF transition in brass captive sleeve compression configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified instrumentation mechanic. Shut off and depressurize the system before disassembly or installation. Hand-tighten the compression nut onto the fitting body, then advance with a wrench per standard compression fitting practice. Apply appropriate thread sealant to the NPTF male threads as required by the application and local codes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Compression\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Male NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -65 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.55 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00268-0304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948880986418,"sku":"00268-0304","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff0a52db1ff0ce83120023a545015526_5ffd4e06-1a11-4deb-85b3-5bf0a8054632.jpg?v=1791675762","url":"https:\/\/voomisupply.com\/products\/midland-industries-00268-0304-captive-sleeve-male-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
