Each washer features a passive grip design that helps maintain a secure, leak-resistant seal at slip joint connections without the need for additional sealants. Silicone construction provides resistance to temperature extremes and chemical exposure, making these washers a durable choice for under-sink drain assemblies, P-traps, and similar slip joint applications. Licensed plumbers and experienced DIYers install these as part of routine trap service or drain line repairs.\u003c\/p\u003e\u003cp\u003eThese washers are suited for use in standard 1-1\/4 inch O.D. slip joint plumbing drain configurations. Typical applications include bathroom sink P-traps, drain extensions, and tailpiece connections where a reliable compression seal is required. The silicone material holds up better than standard rubber in environments subject to hot water discharge or cleaning chemical exposure, making them a practical upgrade or replacement in both new installations and service calls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicone construction resists heat, cold, and common drain cleaning chemicals\u003c\/li\u003e\n\u003cli\u003ePassive grip design helps seat and hold the washer during assembly\u003c\/li\u003e\n\u003cli\u003eSized for 1-1\/4 inch O.D. slip joint tubing\u003c\/li\u003e\n\u003cli\u003eSold as a 2-pack for convenience on single-service calls or as a backup\u003c\/li\u003e\n\u003cli\u003eCarded packaging for easy retail or parts-counter display\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement washer for standard 1-1\/4 inch O.D. slip joint drain fittings used in residential and light commercial plumbing drain assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber or qualified tradesperson.
