Description
The McDonnell & Miller 310451 Stainless Steel Paddle Kit is a genuine OEM replacement component designed for use with the FS4-15SS flow switch. Built to deliver long-lasting performance in hydronic heating and cooling systems, this paddle kit ensures accurate flow detection and reliable system protection in demanding applications.
Product Overview
Flow switches rely on properly sized and material-matched paddles to detect liquid movement and protect pumps, boilers, and other hydronic equipment from low-flow or no-flow conditions. The 310451 paddle kit is constructed from stainless steel, offering superior corrosion resistance compared to standard plastic or brass alternatives — making it well-suited for systems with treated water, glycol solutions, or other potentially corrosive fluids.
