Larsen Supply Co. 02-1840P Fiber Washer 3/4 X 1 Inch

Product Description

The LARSEN SUPPLY CO., INC. 02-1840P is a fiber washer designed for use in plumbing and fluid-handling applications where a compressible, leak-resistant seal is required. Measuring 3/4 inches inner diameter, 1 inch outer diameter, and 1/16 inch thick, this washer creates a reliable face seal between threaded fittings, valves, and fixture connections. The fiber construction provides the compliance needed to seat properly against metal surfaces without damage. Plumbers and pipefitters install this washer during routine maintenance, fixture replacement, and fitting assembly work. It ships bagged, one washer per package.

This washer is suited for residential and light commercial plumbing systems wherever a standard 3/4 inch fiber washer is specified. Typical applications include faucet supply connections, shutoff valve seats, hose bibb repairs, and threaded union joints. The 1/16 inch thickness matches common OEM washer profiles found in a wide range of plumbing fixtures and fittings. It is catalog item 37 in the Larsen Supply washer series.

Installation Notes

Installation is performed by licensed plumbers or qualified service technicians. Shut off the water supply and relieve system pressure before disassembling any fitting or valve. Seat the washer flat against the mating surface before threading the connection hand-tight, then snug with a wrench — do not overtighten, as fiber washers can crush and distort. Inspect the mating surface for nicks or corrosion that could prevent a proper seal.
