Manufactured from modified polyphenylsulfone (PPSU), this fitting accepts ProPEX expansion connections on all three ports, with nominal sizing of 1-1\/4 x 1-1\/4 x 1 inches. The PPSU material provides high heat and chemical resistance, making it well suited for hot and cold water distribution lines. Licensed plumbers and pipefitters install this fitting as part of an Uponor ProPEX expansion-style system.\u003c\/p\u003e\n\u003cp\u003eThis reducing tee is designed for use in residential and light commercial water distribution systems where a branch reduction from a 1-1\/4-inch main line to a 1-inch branch is required. It is commonly used in manifold-based PEX systems, radiant heating distribution, and potable water supply rough-in. The ProPEX end style requires the use of an expansion tool and ProPEX rings or expansion sleeves prior to connection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eProPEX expansion end style on all three ports for reliable, leak-resistant connections\u003c\/li\u003e\n  \u003cli\u003eNominal sizing of 1-1\/4 x 1-1\/4 x 1 inches allows main-line branch reduction in a single fitting\u003c\/li\u003e\n  \u003cli\u003eModified polyphenylsulfone (PPSU) construction resists high temperatures and common water treatment chemicals\u003c\/li\u003e\n  \u003cli\u003eDomestic product designation indicates manufactured in the United States\u003c\/li\u003e\n  \u003cli\u003eCompatible with Uponor ProPEX expansion tooling and fittings ecosystem\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fitting for use within the Uponor ProPEX expansion PEX piping system.
