Made from polymer construction, this fitting is suited for residential and light commercial plumbing distribution systems where a transition between PEX line sizes is required. It arrives in a 25-piece bag, making it a practical choice for rough-in work, manifold branch runs, and multi-zone hydronic or domestic water projects where multiple fittings are needed at once.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in PEX-based plumbing systems where a reducer is needed between a 1-inch main distribution line and a 3\/4-inch branch or supply run. Typical applications include residential new construction, remodel plumbing, and in-floor radiant heating distribution. The barb-style connection works with standard PEX clamp rings or crimp rings as required by the installation method. It is sold in a bag of 25 units to support larger rough-in projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 1-inch PEX to 3\/4-inch PEX in a single fitting\u003c\/li\u003e\n  \u003cli\u003ePolymer construction suitable for potable water and hydronic applications\u003c\/li\u003e\n  \u003cli\u003eBarb design is compatible with crimp ring or clamp ring installation methods\u003c\/li\u003e\n  \u003cli\u003e25-piece bag quantity supports multi-fitting rough-in and distribution work\u003c\/li\u003e\n  \u003cli\u003eCompact barb profile for use in tight framing and manifold configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for 1-inch by 3\/4-inch PEX plumbing systems using barb-style connections secured with crimp or clamp rings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before cutting and fitting. Use a calibrated PEX crimp tool or PEX clamp tool appropriate for the ring type and tubing size being used. Do not over-crimp or under-crimp, as improper ring seating is a leading cause of joint failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: PEX Barb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polymer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Package\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 739236458032\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: SIOUX CHIEF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 645PX43\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIOUX CHIEF","offers":[{"title":"Default Title","offer_id":51383222337842,"sku":"645PX43","price":42.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312672984.png?v=1782590136","url":"https:\/\/voomisupply.com\/products\/sioux-chief-645px43-pex-polymer-barb-reducer-coupling-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
