The LARSEN SUPPLY CO., INC. 02-1836P is a Number 30 fiber washer used as a sealing element in plumbing connections. It measures 0.625 inches inner diameter, 0.875 inches outer diameter, and 0.125 inches thick. The fiber construction compresses to form a leak-resistant seal between mating threaded or flanged fittings. Plumbers and pipefitters install these washers during repairs and new installations where a soft, compressible seating material is required. Each package contains one washer, making it easy to stock individually or in multiples for service work.
This washer is suited for residential and light commercial plumbing applications where a small-diameter fiber seal is needed. Common install scenarios include faucet supply connections, valve packing, and fixture shutoff fittings. The compact size fits standard small-bore fittings and is compatible with typical water supply line assemblies. It is packaged individually in a bag for clean handling and jobsite convenience.
Designed as an OEM-style replacement fiber washer for standard small-bore residential and light commercial plumbing fittings requiring a Number 30 fiber seal.
Shut off the water supply and depressurize the line before replacing any sealing washer. A licensed plumber should verify compliance with local plumbing codes and IPC guidelines. Seat the washer evenly against the fitting surface before tightening — do not overtighten, as excessive force can crush the fiber and compromise the seal. Inspect the mating seating surface for nicks or corrosion before installation.
