The barbed ends create a mechanical grip on the tubing, which is then secured using cinch clamps with a cinch tool or copper crimp rings with a crimp tool. Once installed, the joint is immediately testable to well over 100 psi. The brass construction and lead-free formulation make it suitable for potable water systems in residential and light commercial plumbing applications. Licensed plumbers and pipefitters are the primary installers.\u003c\/p\u003e\u003cp\u003eThis coupling is used in PEX-based water distribution systems where a straight inline connection is needed between two runs of 3\/4-inch PEX tubing. Typical applications include residential hot and cold supply lines, hydronic radiant heating circuits, and retrofit plumbing work where flexible tubing is preferred over rigid copper or CPVC. It is compatible with standard cinch clamp systems using the TV 608-826 cinch clamps and TV 608-743 cinch tool, as well as copper crimp rings and a standard crimp tool per ASTM F 1807 requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLead-free brass construction with less than 0.25% lead by weight on wetted surfaces\u003c\/li\u003e\n\u003cli\u003eBarb insert design secures to 3\/4-inch PEX tubing via cinch clamps or copper crimp rings\u003c\/li\u003e\n\u003cli\u003eImmediately pressure-testable to well over 100 psi after installation\u003c\/li\u003e\n\u003cli\u003eMeets NSF\/ANSI Standard 14-2009 and ASTM F 1807 for potable water transport\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI\/NSF Standard 61 Annex G for lead-free requirements\u003c\/li\u003e\n\u003cli\u003eMeets California AB1953 and Vermont VT S152 low-lead restrictions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3\/4-inch cross-linked polyethylene PEX tubing.

Shut off the water supply and depressurize the line before cutting into any existing tubing. Insert the barbed ends fully into the PEX tubing before applying clamps or crimp rings — partial insertion is the most common cause of joint failure. Verify the completed joint meets system pressure requirements before returning the line to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTubing Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Lead-free brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Barb insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Tubing Type\u003c\/strong\u003e: Cross-linked polyethylene (PEX)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: Testable to well over 100 psi\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\u003eCertifications\u003c\/strong\u003e: NSF\/ANSI 14-2009, ASTM F 1807, ANSI\/NSF 61 Annex G, 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: 0.86 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: SHARKBITE\/CASH ACME\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UC016LFA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SHARKBITE","offers":[{"title":"Default Title","offer_id":51558934610226,"sku":"UC016LFA","price":33.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f0f67decb7a422cac5f86072b4be181.jpg?v=1786423324","url":"https:\/\/voomisupply.com\/products\/sharkbite-uc016lfa-3-4-in-lead-free-brass-barb-coupling-pex","provider":"Voomi Supply","version":"1.0","type":"link"}
