Larsen Supply Co., Inc. 119467 Stepped Cone Washer 6 Pack

Product Description

The LARSEN SUPPLY CO., INC. 119467 is a stepped cone washer designed to create a leak-free compression seal between a 1/2 inch nut and a 3/8 inch tube connection. This type of washer is a standard plumbing component used to transition between different fitting sizes at supply stop connections. It compresses against the fitting seat to form a watertight seal without the need for thread sealant. The 119467 comes packaged in a convenient carded format with 6 washers per package, making it a practical choice for service plumbers who frequently stock common repair parts on their trucks.

This stepped cone washer is suited for residential and light commercial plumbing applications where a 1/2 inch supply nut connects to a 3/8 inch compression tube outlet, such as at angle stop valves, straight stops, and similar supply line fittings. Plumbing technicians and service professionals typically keep this size on hand for faucet supply line replacements and stop valve service calls.

Key Features

• Stepped cone profile transitions between 1/2 inch nut and 3/8 inch tube for a reliable compression seal
• Carded packaging keeps washers organized and protected until point of use

Compatibility

Designed as an OEM-style replacement washer for residential and light commercial plumbing supply connections using a 1/2 inch compression nut with a 3/8 inch tube outlet.

Installation Notes

Installation is typically performed by a licensed plumber or qualified service technician. Shut off the water supply at the main or at the appropriate isolation valve before beginning work and relieve line pressure before disassembling the fitting. Hand-tighten the compression nut onto the fitting seat, then snug with a wrench — avoid overtightening, as excessive force can deform or crack the washer and cause a leak. Follow local plumbing codes, including applicable IPC requirements, for compression fitting installations.
