Larsen Supply Co. 02-1830P No. 57 Fiber Washer

Product Description

The LARSEN SUPPLY CO., INC. 02-1830P is a No. 57 fiber washer used to create leak-free seals at threaded plumbing connections. It measures 1-5/16 inches inner diameter, 1-9/16 inches outer diameter, and 1/16 inch thick. The fiber construction compresses slightly under fastener load, conforming to mating surfaces and providing a reliable static seal. Plumbers and pipefitters install this washer wherever a soft, compressible seating material is required at threaded fittings, unions, and valve packing assemblies. Each package contains one washer, bagged individually for clean handling and jobsite use.

This washer is suited for residential and light commercial plumbing applications where a No. 57 fiber washer is specified. Typical install scenarios include repair of faucets, supply stop valves, compression fittings, and threaded union connections. The fiber material is a standard choice in water supply and low-pressure service lines where a non-metallic seating surface is needed. Plumbing contractors and service technicians keep this size on hand for routine maintenance and emergency repair calls.

Installation Notes

Installation is performed by a licensed plumber or qualified service technician. Shut off the water supply and relieve line pressure before disassembling any fitting or valve. Seat the washer flat against the mating surface before reassembling the connection — do not reuse a compressed or cracked fiber washer. Follow local plumbing code requirements, including IPC guidelines, for approved materials in potable water service lines.
