The barb end secures PEX tubing using stainless steel cinch clamps applied with a compatible cinch tool. Constructed from brass with a wetted surface containing less than 0.25% lead by weight, this adapter meets stringent potable water requirements. It is rated for continuous hot water circulation up to 140 degrees F, making it appropriate for both domestic supply and recirculation applications. Licensed plumbers and pipefitters are the primary installers of this fitting in residential and light commercial systems.\u003c\/p\u003e\n\u003cp\u003eThis adapter is intended for use with PEX tubing meeting ASTM F-876 and ASTM F-877 standards, dimensioned to SDR-9 specifications. It is suited for potable water supply systems in residential and light commercial construction, including hot and cold distribution lines. Its NSF CL-R certification makes it a valid choice in chlorinated hot water recirculation loops where lesser fittings may degrade. The 3\/4-inch barb to 1\/2-inch MPT transition is a common size reduction used when stepping down from a main distribution line to a branch or fixture supply.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free brass construction — wetted surface contains less than 0.25% lead by weight\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch barb end accepts PEX tubing conforming to ASTM F-876 and ASTM F-877 at SDR-9 dimensions\u003c\/li\u003e\n  \u003cli\u003eSecured with stainless steel cinch clamps using cinch tool TV 608-743\u003c\/li\u003e\n  \u003cli\u003eNSF CL-R certified for chlorinated hot water recirculation systems up to 140 degrees F\u003c\/li\u003e\n  \u003cli\u003eMeets NSF 14 and NSF 61 standards for use in potable water systems\u003c\/li\u003e\n  \u003cli\u003eCompliant with CSA B137.5, California AB1953, and Vermont VT S152 low-lead restrictions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with PEX tubing meeting ASTM F-876 and ASTM F-877 standards at SDR-9 dimensional specifications, secured with stainless steel cinch clamps and a compatible cinch tool.

Shut off the water supply and relieve system pressure completely before making any connections. Use the correct cinch tool and stainless steel cinch clamps sized for 3\/4-inch PEX tubing to achieve a proper seal on the barb end. Inspect the male pipe thread end for damage and apply appropriate thread sealant or PTFE tape before threading into the mating fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: 3\/4 inch Barb x 1\/2 inch Male Pipe Thread (MPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Lead-Free Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 140 degrees F (continuous recirculation)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Content (Wetted Surface)\u003c\/strong\u003e: Less than 0.25% by weight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubing Standard\u003c\/strong\u003e: ASTM F-876, ASTM F-877, SDR-9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: NSF 14, NSF 61, NSF CL-R, CSA B137.5, AB1953, VT S152\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12 per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.19 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: SHARKBITE\/CASH ACME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UC138LFA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SHARKBITE","offers":[{"title":"Default Title","offer_id":51558753370418,"sku":"UC138LFA","price":51.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acf8b536b5b92182477cb0c9c334a6b7.jpg?v=1786419696","url":"https:\/\/voomisupply.com\/products\/sharkbite-cash-acme-uc138lfa-pex-barb-adapter-3-4x1-2-mpt","provider":"Voomi Supply","version":"1.0","type":"link"}
