Larsen Supply Co. 02-1800P Fiber Washer 7/16 in Id X 21/32 in Od

Product Description

The LARSEN SUPPLY CO., INC. 02-1800P is a fiber washer designed for use in plumbing assemblies where a soft, compressible sealing element is required. Measuring 7/16 inches inner diameter, 21/32 inches outer diameter, and 1/32 inches thick, this washer provides a reliable seal between mating surfaces in faucets, valves, and pipe fittings. Each package contains one washer, bagged for clean handling. Licensed plumbers and experienced DIYers install fiber washers as part of routine faucet rebuilds, valve stem replacements, and compression fitting repairs.

This fiber washer is suited for residential and light commercial plumbing applications. It is commonly used in compression faucets, shutoff valves, and supply line connections where a soft washer seat is needed to stop drips and prevent leaks. Its compact profile and standardized dimensions make it a go-to replacement part for common faucet and valve repair jobs. The bagged, single-unit packaging keeps the washer clean and ready for immediate installation on the job site or at the service bench.

Key Features

• 7/16 inches inner diameter for precise fit on standard valve stems
• 21/32 inches outer diameter seats flush in common washer pockets
• 1/32 inches thickness provides appropriate compression for sealing
• Fiber construction conforms to seating surfaces to stop drips

Compatibility

Designed as an OEM-style replacement fiber washer for standard compression faucets, shutoff valves, and plumbing fittings requiring a 7/16 inches ID by 21/32 inches OD washer seat.

Installation Notes

Installation is performed by a licensed plumber or qualified technician. Shut off the water supply and relieve line pressure before disassembling any faucet or valve. Replace worn or cracked fiber washers during routine faucet rebuilds or whenever a compression-style valve exhibits a persistent drip. Avoid overtightening the valve stem, as excess torque can damage the fiber washer and accelerate wear on the seat.
