Straight Check Stop for Shower Valves

The Powers 141-176 straight check stop fits 1/2 in NPT connections on shower faucet valves that lack built-in check stops. It is sold as a two-piece package for residential or commercial bath installations.

Bronze Construction with Two Ports

Each valve body is made of bronze and provides two ports in a 2 1/2 in overall length. The manual faucet type requires no electrical supply and threads directly into existing NPT pipework during rough-in or retrofit work.

Sustained Backflow Prevention

Under continuous water pressure the check mechanism holds its seat to prevent cross-flow between hot and cold supplies. The non-CEC-compliant design is intended for installations where local code does not mandate CEC certification. Not for systems requiring certified low-lead or CEC-approved components.
