Jerich 401642 Cold Ceramic Stem 2-3/4 in 16 Point

Product Description

The JERICH 401642 is a cold ceramic stem replacement designed for use in commercial and residential plumbing valve assemblies. Ceramic stems provide reliable shutoff performance and resist wear better than traditional rubber-seat designs, making them a preferred choice for long-service valve repairs. This stem measures 2-3/4 inches in length and features a 16-point spline configuration, ensuring a precise fit in compatible valve bodies. Licensed plumbers and experienced service technicians typically install ceramic stems during valve rebuilds or drip-stop repairs.

The 401642 is suited for cold-water valve applications where a ceramic disc or ceramic-seat stem is specified. The 16-point spline drive mates with standard valve handles designed for that configuration. This type of stem is commonly found in commercial fixture valves, lavatory faucets, and utility service valves that require durable, low-maintenance components. The 2-3/4 inch length positions it for a specific valve body depth, so confirming stem length before installation is essential.

Key Features

• Ceramic construction for extended wear life compared to rubber-seat stems
• 2-3/4 inch stem length for precise valve body fitment
• 16-point spline configuration for secure handle engagement
• Designed for cold-water service valve applications
• OEM-style replacement for Altman-brand valve assemblies

Compatibility

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician. Shut off the water supply and relieve line pressure completely before disassembling the valve body. Inspect the valve seat for scoring or damage before installing the new ceramic stem, as a damaged seat will shorten stem life. Follow all applicable local plumbing codes, including IPC guidelines, when performing valve service.
