Bsc Preferred DIB855-03 Poly Slip Joint Washers

Product Description

The BSC PREFERRED DIB855-03 is a six-piece card of polyethylene slip-joint washers sized for 1-1/4 inch and 1-1/2 inch drain fittings. Each card includes three washers of each size, giving a plumber or drain service tech both common sizes in a single purchase. These washers create a watertight seal at slip-joint connections in sink drains, P-traps, and similar low-pressure drain assemblies. The flexible poly construction compresses evenly against slip-joint nuts and fittings without cracking under normal service conditions. Sold as one card containing six washers total.

Slip-joint washers are a standard consumable in residential and light commercial plumbing service. They are used when re-assembling P-traps, tailpieces, and drain extensions under kitchen and bathroom sinks. Having both the 1-1/4 inch and 1-1/2 inch sizes on a single card makes this a convenient bench or van stock item for plumbers handling a variety of fixture drain configurations in a single service call.

Key Features

• Six washers per card — three 1-1/4 inch and three 1-1/2 inch
• Poly construction resists cracking and deformation at slip-joint connections
• Covers both common residential drain fitting sizes in one package
• Lightweight card packaging suitable for parts drawer or van stock storage

Compatibility

Designed as a standard replacement for polyethylene slip-joint washers used in 1-1/4 inch and 1-1/2 inch P-trap and drain fitting assemblies common in residential and light commercial plumbing fixtures.

Installation Notes

Slip-joint washers are installed by licensed plumbers or qualified service technicians during drain assembly or trap replacement. Shut off water supply and clear standing water from the drain before disassembly. Hand-tighten slip-joint nuts to seat the washer, then snug with channel-lock pliers — avoid over-tightening, which can distort or extrude the washer and cause leaks. Work should conform to applicable local plumbing codes and IPC guidelines.
