The body is manufactured from lead-free DZR brass, meeting NSF\/ANSI 61 and NSF 372 requirements for potable water contact. Two color-coordinated crimp rings are included: a black ring for the PEX side and a copper-colored ring for the Polybutylene side, eliminating guesswork during installation. Plumbers and pipefitters use this fitting as a low-cost, direct transition where existing Polybutylene supply lines meet new PEX distribution runs.\u003c\/p\u003e\u003cp\u003eThis coupling is suited for residential and light commercial potable water distribution systems as well as hydronic heating applications. It is a practical solution during Polybutylene pipe remediation projects, where sections of aging Poly pipe are being replaced or extended with PEX tubing. The two-ring system ensures each side receives the correct crimp ring for its material without requiring separate purchases.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLead-free DZR brass construction meets NSF\/ANSI 61 and NSF 372 standards for potable water safety\u003c\/li\u003e\n\u003cli\u003eTransitions 1\/2-inch PEX tubing directly to 1\/2-inch Polybutylene pipe in a single fitting\u003c\/li\u003e\n\u003cli\u003eIncludes two color-coordinated crimp rings — black for PEX, copper-colored for Polybutylene\u003c\/li\u003e\n\u003cli\u003eCompatible with potable water distribution and hydronic heating systems\u003c\/li\u003e\n\u003cli\u003eCrimp-style connection works with standard PEX crimp tools and go\/no-go gauges\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for potable water distribution and hydronic heating applications.

Shut off the water supply and depressurize the line before cutting into any existing pipe. Follow local plumbing codes and IPC guidelines for transition fittings in potable water systems. Verify that the correct color-coded crimp ring is placed on the correct pipe material before crimping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Lead-Free DZR Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Crimp (PEX to Polybutylene)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: NSF\/ANSI 61, NSF 372\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.109 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RWC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UC4008LFA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RWC","offers":[{"title":"Default Title","offer_id":51342761558322,"sku":"UC4008LFA","price":18.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310551282.jpg?v=1782005828","url":"https:\/\/voomisupply.com\/products\/rwc-uc4008lfa-sharkbite-pex-polybutylene-coupling-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
