Stem Replacement Kit for Powers Valves

The Powers 410-378 kit provides a new stem assembly for manual faucets. It fits Powers valve series 400, 410 and 2000, covering both hot and cold cartridge positions. This part restores proper water control when the original stem wears out.

Sustained drip resistance

The replacement stem is built to maintain a tight seal under daily pressure cycles. It resists the gradual wear that causes persistent dripping after months of repeated handle operation. The design matches the original valve tolerances so performance stays consistent over time.

Brass construction with standard splines

The stem body uses corrosion-resistant brass suited to potable water lines. Its spline pattern matches the factory handle broach, so existing handles reattach without adapters. Threads conform to Powers series specifications, allowing direct installation into the valve body.

Questions about this item

Does the 410-378 stem kit generate noise, heat or draw power when the faucet runs all day?

The kit is a mechanical cartridge replacement with no electrical parts, so it produces no noise, heat or power draw during continuous use.

What existing valve body must I already have for the 410-378 stem to fit?

It fits Powers valve bodies in Series 400, 410 or 2000; the cartridge will not work with other brands or series.

Will the 410-378 cartridge operate correctly alongside older Powers trim or handles I keep?

Yes, the stem replaces the internal cartridge only, so original trim, handles and escutcheons from Series 400, 410 or 2000 remain compatible.
