It combines a 1\/4-inch compression inlet with a 1\/8-inch female NPTF port and a 1\/8-inch male NPTF port, making it well suited for routing or splitting lines in tight plumbing assemblies. Rated to 300 psi and capable of handling temperatures from -65 to 250 degrees F, this fitting performs across a wide range of service conditions. Licensed plumbers, HVAC technicians, and refrigeration techs routinely use this type of fitting when transitioning between compression and threaded connections on control or instrument lines.\u003c\/p\u003e\n\u003cp\u003eThe 18307 is intended for use with copper, aluminum, and thermoplastic tubing in residential and light commercial applications. Typical install scenarios include instrument air lines, fuel supply connections, refrigeration sensing lines, and similar low-diameter branch plumbing where a compression-to-NPT transition is needed in a single body. The compact 0.72-inch body size allows it to fit in confined spaces common to equipment cabinets, control panels, and mechanical rooms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eForged brass construction for strength and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e300 psi working pressure rating\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -65 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompatible with copper, aluminum, and thermoplastic tubing\u003c\/li\u003e\n  \u003cli\u003eCombines compression and NPTF threaded connections in a single tee body\u003c\/li\u003e\n  \u003cli\u003e7\/16-24 x 1\/8-27 thread specification for precise thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with copper, aluminum, and thermoplastic tubing.

Shut off and depressurize the system completely before disassembling or installing any compression fitting. Do not overtighten the compression nut, as brass fittings can deform the ferrule seat if over-torqued. Ensure tubing is cut cleanly and squarely and is fully seated before tightening. NPTF threads are designed to seal on the thread form itself; apply thread sealant or tape only as required by local code or system compatibility.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection 1 Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection 1 Type\u003c\/strong\u003e: Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection 2 Size\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection 2 Type\u003c\/strong\u003e: Female NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection 3 Size\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection 3 Type\u003c\/strong\u003e: Male NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Specification\u003c\/strong\u003e: 7\/16-24 x 1\/8-27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 psi\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\u003eBody Size\u003c\/strong\u003e: 0.72 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to End\u003c\/strong\u003e: 0.53 x 0.72 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.55 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.45 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 18307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67950600061234,"sku":"18307","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f82547cf6f77d89b76a80af5672a968_2eee67c7-f507-425e-913b-bf4b03860f65.jpg?v=1791723003","url":"https:\/\/voomisupply.com\/products\/midland-industries-18307-brass-compression-tee-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
