The LARSEN SUPPLY COMPANY LAR02-2293 slip joint washers are a 2-pack solution-type washers sized for 1-1/2 inch tubular drain applications. These washers are compatible with both plastic and metal tubular drain assemblies, making them a versatile replacement part for common sink drain repairs. Installed at slip joint connections, they create a watertight seal that prevents leaks at trap arms, P-traps, and extension tubes. Plumbers and drain service technicians keep these on hand as a standard consumable for residential drain work.
These washers are suited for residential and light commercial plumbing applications where 1-1/2 inch tubular drain components are used. Common installation points include kitchen sink P-traps, bathroom lavatory drains, and similar tubular drain configurations. The dual compatibility with plastic and metal tubular fittings makes them practical for service calls involving mixed-material drain assemblies.
Designed as an OEM-style replacement slip joint washer for 1-1/2 inch plastic and metal tubular drain assemblies in residential and light commercial plumbing systems.
Installation is performed by licensed plumbers or experienced DIYers during P-trap and tubular drain assembly repairs. Shut off water supply and clear the trap of standing water before disassembling slip joint connections. Hand-tighten slip joint nuts to seat the washer, then snug with channel-lock pliers — avoid overtightening plastic fittings, which can crack the nut or fitting body. Verify no leaks by running water and inspecting all slip joint connections after reassembly.
