Replacement Bonnet for E427 and E428 Valves

The Powers 427-019 bonnet assembly fits Series E427 and E428 shower valves. It serves as a direct replacement part for manual faucet installations. This component restores valve function without requiring a full valve body change. It is intended for maintenance and repair tasks.

Manual Faucet Compatibility Requirement

This bonnet is designed exclusively for manual faucet valve types. It will not operate with electronic or pressure-balance cartridges outside the specified series. Verify the existing valve model number before ordering to ensure correct fit. Mismatched series will prevent proper assembly.

Non CEC Compliant Status

The assembly carries a non CEC compliant designation, limiting its use in jurisdictions with strict efficiency codes. California Proposition 65 warnings apply for cancer and reproductive harm risks. No additional cartridges or seals are bundled with this bonnet. The separate 427-017 cartridge must be sourced if required.
