Constructed from lead-free brass with a 9\/16-24 x 1\/2-14 thread specification, this coupling meets requirements for potable water and other plumbing applications where lead-free materials are mandated. It is rated for temperatures from -40 to 250 degrees F, making it suitable for both cold and hot water service lines. Licensed plumbers and pipefitters install this type of fitting in residential and light commercial plumbing systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used where a compression-style tubing connection must transition to a female iron pipe thread. It is compatible with copper, aluminum, or plastic tubing on the compression side, providing flexibility across common plumbing installations. Typical applications include water supply lines, fixture connections, and branch line transitions where a threaded female port is required on one end and a compression connection on the other.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free brass construction meets lead-free compliance requirements for potable water systems\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch compression inlet transitions to 1\/2-inch FIP outlet\u003c\/li\u003e\n  \u003cli\u003eThread specification: 9\/16-24 x 1\/2-14\u003c\/li\u003e\n  \u003cli\u003eRated from -40 to 250 degrees F for broad service range\u003c\/li\u003e\n  \u003cli\u003eCompatible with copper, aluminum, or plastic tubing on the compression side\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with copper, aluminum, or plastic tubing on the 3\/8-inch compression connection.

Shut off the water supply and relieve line pressure before making or breaking any connections. Hand-tighten the compression nut first, then use an appropriate wrench to finish; do not overtighten, as brass threads and compression sleeves can be damaged. Verify that tubing is cut cleanly and fully seated before tightening the compression nut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 3\/8 inches (Compression)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/2 inches (FIP)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Specification\u003c\/strong\u003e: 9\/16-24 x 1\/2-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Lead-Free Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -40 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Tubing\u003c\/strong\u003e: Copper, Aluminum, Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.075 pounds\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: LF66-68\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67949931561266,"sku":"LF66-68","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9493aab74c8123b0848bbcf5dae8814f_5b7d5482-d4a3-49fb-bd7f-5b75bea89d86.jpg?v=1791704337","url":"https:\/\/voomisupply.com\/products\/midland-industries-lf66-68-compression-coupling-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
