The fitting transitions a 1\/4 inch compression connection to a 1\/2 inch FNPTF (female National Pipe Taper Fuel) port. It is rated to 300 psi and operates across a temperature range of -65 to 250 degrees F. The 18148 is commonly installed by plumbers, HVAC technicians, and mechanical contractors where copper, aluminum, or thermoplastic tubing must terminate at a threaded fitting. Thread dimensions are 7\/16-24 on the compression side and 1\/2-14 NPT on the female port side.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for residential and light commercial plumbing, refrigeration, and gas distribution applications where a compression tube meets a female pipe thread connection. It is compatible with copper, aluminum, and thermoplastic tubing on the compression side. The compact form factor, with a 0.87 inch hex and a center-to-end dimension of 1.02 inches, makes it practical in tight installations where clearance is limited. Typical install scenarios include appliance supply lines, instrument tubing, and low-pressure gas or fluid control systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions 1\/4 inch compression tubing to 1\/2 inch FNPTF threaded port\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi working pressure\u003c\/li\u003e\n  \u003cli\u003eTemperature range of -65 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompatible with copper, aluminum, and thermoplastic tubing\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eCompact hex size of 0.87 inches for use in confined spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with copper, aluminum, and thermoplastic tubing on the compression side.

Shut off all fluid or gas supply and depressurize the line before disassembly or installation. Hand-tighten the compression nut first, then apply a final snug turn with an appropriately sized wrench on the 0.87 inch hex  -  do not overtighten, as brass compression fittings can deform the ferrule or crack if over-torqued. Apply thread sealant or PTFE tape to the NPT threads as required by local plumbing codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1\/4 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\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: FNPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread\u003c\/strong\u003e: 7\/16-24 x 1\/2-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.87 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to End\u003c\/strong\u003e: 1.02 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.85 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorking 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\u003eWeight\u003c\/strong\u003e: 0.12 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: 18148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67952855679282,"sku":"18148","price":21.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f6e6214b39708e93c036f0f87baeb3d.jpg?v=1791753250","url":"https:\/\/voomisupply.com\/products\/midland-industries-18148-brass-compression-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
