Manufactured from polyphenylsulfone (PPSU), this fitting delivers high heat resistance and long-term durability suited to both hot and cold water service. The ProPEX end style requires a ProPEX expansion tool to expand the pipe and ring before installation, creating a secure, leak-resistant connection. This fitting is domestically produced and intended for installation by licensed plumbers and mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in residential and light commercial plumbing and hydronic heating applications where a straight inline connection between two PEX tubing sections is required. Typical scenarios include repairing a cut or damaged tubing run, extending an existing PEX line, or connecting two segments during a new rough-in. The ProPEX expansion method is common in multi-family, commercial, and high-volume residential installations where connection speed and joint integrity are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-inch nominal size for high-flow plumbing and hydronic distribution lines\u003c\/li\u003e\n  \u003cli\u003eProPEX end style requires expansion tool for a compression-fit, tool-secured joint\u003c\/li\u003e\n  \u003cli\u003ePolyphenylsulfone (PPSU) construction provides superior thermal and chemical resistance compared to standard plastic fittings\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured fitting\u003c\/li\u003e\n  \u003cli\u003eStraight coupling configuration for inline tubing connections and repairs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style ProPEX fitting for use with 2-inch PEX tubing in expansion-style PEX plumbing and hydronic systems requiring PPSU fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a calibrated ProPEX expansion tool and the correct size expansion ring; always verify tool and ring size match the tubing and fitting nominal size before expanding. Shut off and depressurize the water supply completely before cutting into any existing line. This fitting is typically installed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Allow adequate time after expansion for the fitting connection to reach full memory-recovery before pressurizing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: ProPEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyphenylsulfone (PPSU)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\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: UPONOR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: Q4772020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51524911530290,"sku":"PLCOUP2","price":47.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97355d283628dd92a10fe31012cf679f_1f69589f-c62f-4f05-9dd9-25eb83a84e3d.jpg?v=1785461457","url":"https:\/\/voomisupply.com\/products\/uponor-q4772020-propex-coupling-2-inch-nominal","provider":"Voomi Supply","version":"1.0","type":"link"}
