PPSU (polyphenylsulfone) is a high-performance thermoplastic well suited to hot and cold potable water distribution. This tee connects a 1-inch run to two 3\/4-inch branch lines using the expansion method, where the fitting is inserted after the PEX-A tubing end is expanded with a compatible expansion tool. Licensed plumbers and pipefitters install this fitting in residential and light commercial plumbing rough-in work where PEX-A distribution systems are specified.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in PEX-A water distribution systems in residential and light commercial construction. The F1960 expansion connection style is common in new construction and remodel plumbing where PEX-A tubing is run from a manifold or main line to branch points serving fixtures. The 1-inch by 3\/4-inch by 3\/4-inch configuration is a standard reducing tee used when transitioning from a main supply trunk to smaller branch runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePPSU construction offers high heat and chemical resistance for potable water service\u003c\/li\u003e\n  \u003cli\u003eF1960 expansion connection style compatible with PEX-A tubing only\u003c\/li\u003e\n  \u003cli\u003e1-inch inlet by 3\/4-inch by 3\/4-inch outlet configuration for reducing branch runs\u003c\/li\u003e\n  \u003cli\u003eLead-free material suitable for potable hot and cold water systems\u003c\/li\u003e\n  \u003cli\u003eExpansion-style connection creates a reliable, leak-resistant joint as the tubing memory contracts around the fitting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with F1960 PEX-A tubing systems.

Shut off the water supply and relieve system pressure before beginning work. Use only a calibrated F1960 expansion tool sized to match each tubing diameter; do not attempt to force the fitting without proper expansion. Allow expanded tubing ends adequate time to contract fully around the fitting before pressurizing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PPSU (Polyphenylsulfone)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Standard\u003c\/strong\u003e: ASTM F1960 (PEX-A Expansion)\u003c\/li\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 x 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducing Tee\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 739236715005\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: 641WP433\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIOUX CHIEF","offers":[{"title":"Default Title","offer_id":51383998251314,"sku":"641WP433","price":25.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312673909.png?v=1782614612","url":"https:\/\/voomisupply.com\/products\/sioux-chief-641wp433-pex-a-ppsu-tee-1x3-4x3-4-f1960","provider":"Voomi Supply","version":"1.0","type":"link"}
