This fitting is part of the NIBCO Press System, which uses a crimp-style installation method that eliminates the need for open flame or soldering. A unique N witness mark becomes visible on the fitting once the connection is properly crimped, providing a clear visual confirmation of a complete joint. Licensed plumbers and pipefitters install this fitting using compatible pressing tools, jaws, and chains. It is suited for both residential and commercial applications across a range of water-based systems.\u003c\/p\u003e\n\u003cp\u003eThis adapter fits into water distribution, radiant floor heating, municipal water supply, geothermal climate control, snow melt, and drip irrigation systems. It can also be installed in underground applications where appropriate. The reducing configuration — 3\/4 inch PEX on one end and 1\/2 inch press on the other — makes it useful when transitioning between different tubing sizes within the same system. No additional threading or adhesive bonding is required during installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCrimp-style press connection eliminates open flame — no soldering required\u003c\/li\u003e\n  \u003cli\u003eN witness mark provides visual confirmation of a fully seated, completed crimp\u003c\/li\u003e\n  \u003cli\u003eReducing adapter transitions 3\/4-inch PEX to 1\/2-inch press connection\u003c\/li\u003e\n  \u003cli\u003eRated for underground installation in addition to above-grade use\u003c\/li\u003e\n  \u003cli\u003eCopper or copper alloy construction offers durability and low maintenance\u003c\/li\u003e\n  \u003cli\u003eBacked by a 50-year limited warranty from NIBCO\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use within the NIBCO Press System for joining PEX tube in residential and commercial water distribution, radiant floor heating, municipal water supply, geothermal climate control, snow melt, and drip irrigation applications.

Shut off the water supply and depressurize the line before beginning any work. Verify that the tubing is cut cleanly and fully seated into the fitting before crimping. Inspect the N witness mark after crimping to confirm the connection is complete. Follow all applicable local plumbing codes and manufacturer technical data sheets for engineering and installation requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: PEX x Press\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper or copper alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 50-year limited\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 039923308139\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: NIBCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PC604P34X12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51383492280626,"sku":"PC604P34X12","price":32.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312673099.png?v=1782598317","url":"https:\/\/voomisupply.com\/products\/nibco-pc604p34x12-pex-press-adapter-3-4-x-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
