It serves as a transition fitting in refrigeration, HVAC, and plumbing systems where copper or aluminum tubing must terminate at a threaded female port. The all-brass construction provides reliable corrosion resistance and durability under typical system pressures. Licensed HVAC technicians and plumbers install this type of adapter when routing tubing to valves, manifolds, or equipment ports that use standard female pipe threads.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for residential and light commercial applications. Typical install scenarios include connecting refrigerant or condensate lines, ice maker supply lines, and similar small-diameter tubing runs where a compression-to-FPT transition is required. Its compact dimensions make it practical in tight spaces around equipment cabinets and valve assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16 inch compression inlet connects directly to compatible OD tubing without soldering\u003c\/li\u003e\n\u003cli\u003e3\/8 inch FPT outlet threads into standard female pipe thread ports\u003c\/li\u003e\n\u003cli\u003eAll-brass body resists corrosion in wet and refrigerant-adjacent environments\u003c\/li\u003e\n\u003cli\u003eCompact profile at 1.2 inches length and 0.8 inches width for use in confined spaces\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1 unit for single-piece replacement needs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement compression adapter for systems requiring a 5\/16 inch compression to 3\/8 inch FPT transition in brass fittings applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or HVAC technicians following applicable IPC and IFGC guidelines. Shut off the water or refrigerant supply and depressurize the line before removing or installing any compression fitting. Hand-tighten the compression nut first, then snug with a wrench  -  do not overtighten, as over-compression can deform the ferrule and cause leaks. Apply thread sealant or PTFE tape to the FPT threads per standard practice before making up the connection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 5\/16 inches\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: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: FPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.065 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: 18151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67950477574450,"sku":"18151","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ab4a97b820eef84d0e1bb97fa3ccd09.jpg?v=1791719034","url":"https:\/\/voomisupply.com\/products\/midland-industries-18151-brass-compression-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
