The barb end is compatible with stainless steel cinch clamps installed using a cinch tool, providing a secure, corrosion-resistant joint in potable water systems. Constructed from brass and meeting NSF 14 and NSF 61 standards, this adapter is suitable for both cold and hot water service. NSF CL-R certification confirms suitability for hot water recirculation systems where chlorinated water up to 140 degrees F is continuously circulated. Lead content of the wetted surface is less than 0.25% by weight, satisfying California AB1953 and Vermont VT S152 low-lead requirements.\u003c\/p\u003e\n\u003cp\u003eThis adapter is used in residential and light commercial plumbing installations where PEX tubing is transitioned to a threaded fitting at a valve, fixture shutoff, water heater connection, or manifold port. It is installed by licensed plumbers and experienced pipefitters working with PEX systems built to SDR-9 dimensional standards per ASTM F-876 and ASTM F-877. Typical applications include potable water supply lines, hot water recirculation loops, and any system requiring a reliable barb-to-female-thread transition with cinch-clamp retention.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free brass construction with wetted-surface lead content below 0.25% by weight\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch barb end secured with stainless steel cinch clamps using cinch tool TV 608-743\u003c\/li\u003e\n  \u003cli\u003eNSF 14 and NSF 61 listed for use in potable water systems\u003c\/li\u003e\n  \u003cli\u003eNSF CL-R certified for hot water recirculation with chlorinated water up to 140 degrees F\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM F-876 and ASTM F-877 for PEX tubing to SDR-9 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eComplies with 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 connected via stainless steel cinch clamps and cinch tool TV 608-743, conforming to ASTM F-876 and ASTM F-877 SDR-9 dimensional standards.

Shut off the water supply and relieve system pressure before cutting into any existing line or removing existing fittings. Apply an appropriate thread sealant or PTFE tape to the female NPT threads before making up the threaded connection. Use the correct cinch tool and properly sized stainless steel cinch clamps on the barb end to achieve a leak-free crimp; do not substitute worm-gear clamps.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarb Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4 inch Female NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Lead-Free Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Temperature\u003c\/strong\u003e: 140 degrees F (continuous recirculation, chlorinated water)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.02 pounds (package of 12)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12 pieces per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: NSF 14, NSF 61, NSF CL-R, CSA B137.5, ASTM F-876, ASTM F-877, AB1953, VT S152\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: UC068LFA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SHARKBITE","offers":[{"title":"Default Title","offer_id":51559882457394,"sku":"UC068LFA","price":50.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09c0ef1bf45dd168e3787f3b82d565d5_abc88b31-e96e-42a2-920c-b2d829cbf418.jpg?v=1786443491","url":"https:\/\/voomisupply.com\/products\/sharkbite-cash-acme-uc068lfa-pex-barb-adapter-1-2x3-4-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
