Perko Flush Pro Valve Kit - 1-1/4"

The Perko Flush Pro Valve Kit in 1-1/4" size is designed for raw water cooling systems on cruising boats, fishing vessels, and offshore platforms. This kit addresses maintenance challenges related to saltwater corrosion and mineral buildup in through-hull seacock assemblies. It is an essential component for those operating diesel inboards or cooling-intensive twin-engine setups.

The Flush Pro design isolates the engine cooling circuit, allowing fresh water to be introduced directly into the intake line. This process effectively flushes out salt deposits, algae, and sediment without needing to run the engine. Constructed from corrosion-resistant materials, this valve kit is built to withstand both saltwater and brackish environments.

Ideal for commercial fishermen and naval architects, the valve kit serves as both a preventive upgrade and a reliable repair solution. Its 1-1/4" port size ensures compatibility with standard marine cooling systems found on mid-range cruisers and popular engine packages. Installation is straightforward, requiring only basic plumbing knowledge.
