The integral stop positions the tubing consistently for repeatable press connections without soldering. At 4 inches, this fitting suits larger-diameter runs found in commercial plumbing, mechanical rooms, and high-flow hydronic distribution systems. A licensed plumber or pipefitter installs this fitting using a compatible press tool and jaw set, eliminating open flame from the connection process.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for commercial and residential applications where flame-free joining is required or preferred. It is used in potable water supply, hydronic heating and cooling distribution, and fire suppression pre-work where copper press fittings are specified. The press x press end configuration accepts standard copper tubing on both ends, making it a straightforward in-line repair or extension fitting for 4-inch copper pipe systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress x press end configuration for flame-free, tool-pressed copper connections\u003c\/li\u003e\n  \u003cli\u003eIntegral stop ensures consistent tubing insertion depth on both ends\u003c\/li\u003e\n  \u003cli\u003e4-inch size suits commercial plumbing and large-diameter hydronic systems\u003c\/li\u003e\n  \u003cli\u003eCopper construction provides corrosion resistance in water and hydronic fluid service\u003c\/li\u003e\n  \u003cli\u003eEliminates soldering, reducing labor time and open-flame risk on the job site\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style press fitting for use with standard 4-inch copper tubing in press-fit plumbing and hydronic piping systems.

Shut off and depressurize the system and drain the line before making the connection. Ensure tubing is cut square, deburred, and fully seated against the internal stop before pressing. Work must comply with applicable local plumbing codes and IPC requirements for press-fit copper fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Press x Press\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 4 inches\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: PRESCOUP4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51524655415602,"sku":"COUP4","price":150.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/888601d9b970993d1e198249fe446764_4ff9ad69-1b1e-407c-9825-094cd0cd8dcc.jpg?v=1785454262","url":"https:\/\/voomisupply.com\/products\/nibco-prescoup4-copper-press-coupling-with-stop-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
