Larsen Supply Co., Inc. 0-1027 Diaphragm Washer 2 Pack

Product Description

The LARSEN SUPPLY CO., INC. 0-1027 is a rubber diaphragm washer packaged in a 2-count retail-carded set, designed for use in faucet repair applications under the American Standard Aqua Seal product line. Diaphragm washers serve as the primary sealing element inside compression and diaphragm-style faucet stems, preventing water bypass when the valve is closed. This replacement washer is made from rubber for reliable sealing and is suited for plumbers and experienced DIYers performing routine faucet stem service. The carded retail format makes it convenient for counter or peg-display stocking in supply houses or service vans.

This washer is used in residential and light commercial plumbing applications where American Standard Aqua Seal faucet stems require seal replacement. It is a common maintenance item during faucet rebuilds, particularly when a valve drips from the spout after closing. Plumbing contractors and service techs typically stock diaphragm washers as a consumable alongside faucet stem kits. The 2-pack format supports a single repair job or provides a spare for future service calls.

Installation Notes

Installation is performed by a licensed plumber or qualified service technician. Shut off the water supply at the fixture stop valve or main shutoff before disassembling the faucet stem. Remove the stem, inspect the seat for damage, and seat the diaphragm washer correctly before reassembly. Work should comply with applicable local plumbing codes and IPC guidelines.
