PPSU (polyphenylsulfone) is a high-performance thermoplastic known for its resistance to heat, pressure, and chemical exposure, making it a dependable choice for PEX expansion-style connections. This coupling joins two sections of 1-inch PEX tubing using the cold-expansion method required by the F1960 specification. Licensed plumbers and pipefitters install this fitting in potable water distribution and radiant heating systems where a reliable, tool-driven connection is required.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial plumbing applications where 1-inch PEX-A tubing is used. It is commonly installed in water supply lines, manifold distribution systems, and hydronic radiant floor heating layouts. The F1960 cold-expansion method requires an expansion tool and the appropriate size expansion ring or integrated ring fitting. This part is intended for use with PEX-A tubing only, as the cold-expansion process is not compatible with PEX-B or PEX-C tubing types.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePPSU construction offers high heat and pressure resistance for demanding plumbing environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM F1960 standard for cold-expansion PEX fittings\u003c\/li\u003e\n  \u003cli\u003e1-inch nominal size for use with standard 1-inch PEX-A tubing\u003c\/li\u003e\n  \u003cli\u003eNo-solder, no-crimp installation using the cold-expansion method\u003c\/li\u003e\n  \u003cli\u003eSuitable for potable water and hydronic heating applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an F1960-compliant cold-expansion PEX coupling for use with 1-inch PEX-A tubing in residential and light commercial plumbing and radiant heating systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed plumber in accordance with local plumbing codes and the IPC. Shut off the water supply and relieve system pressure before cutting into any existing line. A calibrated F1960 expansion tool and correctly sized expansion rings are required to make the connection. Do not use this fitting with PEX-B or PEX-C tubing, as the cold-expansion method requires the memory properties of PEX-A.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM F1960\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PPSU (Polyphenylsulfone)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Cold Expansion PEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662545126883\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: LEGEND VALVE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 461-915\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEGEND VALVE","offers":[{"title":"Default Title","offer_id":51468113477938,"sku":"461-915","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313948247.jpg?v=1783913738","url":"https:\/\/voomisupply.com\/products\/legend-valve-461-915-ppsu-pex-coupling-1-inch-f1960","provider":"Voomi Supply","version":"1.0","type":"link"}
