Danco 36593B Slip Joint Washer 7/8 X 13/32 in Orange Rubber

Product Description

The DANCO 36593B is an orange rubber slip joint washer designed to create a watertight seal at drain slip joint connections. Molded in a cone (tapered) profile, it conforms to the mating surfaces of standard slip joint fittings to stop leaks at sink drain assemblies and P-traps. It measures 7/8 inches in outer diameter by 13/32 inches and is sold individually. The cone-molded geometry allows the washer to seat evenly under compression without rolling or distorting, which is a common failure point with flat washers in the same application. Plumbers and plumbing technicians reach for this part as a routine repair item during drain service calls.

This washer is suited for residential and light commercial sink drain repairs, including kitchen sinks, bathroom lavatories, and utility sinks. It is typically installed at the slip nut connection between a drain tailpiece and a P-trap or between trap sections. The orange rubber compound provides flexibility and resilience appropriate for drain-line service conditions.

Key Features

• 7/8 inch outer diameter fits standard residential slip joint drain fittings

Installation Notes

Installation is performed by licensed plumbers or experienced DIYers during sink drain service. Shut off water supply and clear standing water from the trap before disassembly. Hand-tighten the slip nut over the new washer, then snug with channel-lock pliers — overtightening can deform the rubber and cause leaks. Check for leaks by running water through the drain after reassembly.
