It bridges 1-1\/2 inch and 1-1\/4 inch tube sizes in a single fitting, making it a practical solution for under-sink drain assemblies and P-trap configurations. The coupling ships complete with two 1-1\/2 inch washers and two 1-1\/2 inch by 1-1\/4 inch reducer washers, along with the necessary slip joint nuts, so no additional hardware is required for a leak-free installation. The white finish is sized to blend with standard white ABS and PVC drain trim. Plumbers and plumbing technicians reach for this fitting when extending or connecting drain lines without solvent-welded joints.\u003c\/p\u003e\u003cp\u003eThis coupling is suited for residential and light commercial plumbing applications, primarily in lavatory, kitchen sink, and utility sink drain configurations. It is used wherever a removable, hand-tightened slip joint connection is preferred over a glued fitting, including P-trap extensions, tailpiece connections, and drain line repairs. The dual-washer kit allows the same fitting to accommodate both 1-1\/2 inch full-size and 1-1\/4 inch reduced-size tube ends without sourcing additional reducer inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAccepts both 1-1\/2 inch and 1-1\/4 inch tube connections using included reducer washers\u003c\/li\u003e\n\u003cli\u003eIncludes two 1-1\/2 inch washers and two 1-1\/2 inch by 1-1\/4 inch reducer washers\u003c\/li\u003e\n\u003cli\u003eAll slip joint nuts included — no additional hardware required\u003c\/li\u003e\n\u003cli\u003eWhite PVC construction matches standard white drain trim and fixtures\u003c\/li\u003e\n\u003cli\u003eSlip joint design allows tool-free disassembly for future service or cleaning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style slip joint replacement coupling compatible with standard 1-1\/2 inch and 1-1\/4 inch drain tube applications in residential and light commercial plumbing systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber or qualified plumbing technician. Shut off the water supply and clear the drain line of standing water before beginning work.
