Shurflo by Pentair 1-1/4" Raw Water Strainer - 20 Mesh Screen

The Shurflo by Pentair 1-1/4" Raw Water Strainer with 20 Mesh Screen (MPN 253-400-01) is a specialized intake protection device engineered to shield raw water systems from debris, sediment, and particulate contamination. Built for marine, auxiliary power, and fluid transfer applications where water quality cannot be controlled, this strainer protects downstream pumps and components from wear, clogging, and premature failure by filtering incoming water before it reaches critical system hardware.

The 20 mesh screen rating creates a nominal separation barrier effective against sand, silt, small shells, and other common waterborne solids found in bait tanks, livewells, and open-water intake scenarios. The clear twist-off bowl enables rapid visual inspection of accumulated debris without disassembly, while the removable stainless steel screen allows field cleaning without tools. An integral o-ring seal ensures leak-free operation under system pressure, eliminating bypass risk that would compromise filtration effectiveness. The 1-1/4" connection size matches standard raw water intake ports on bilge pumps, washdown systems, and auxiliary engines across marine platforms.

This strainer is essential for operators maintaining offshore vessels, commercial fishing platforms, tactical water craft, and emergency response waterborne equipment where intake contamination poses operational risk. Freshwater and saltwater environments both generate particulate loads that accumulate rapidly in high-flow or intermittent-use scenarios. Regular bowl inspection and screen cleaning extend pump service intervals significantly and reduce unplanned downtime in mission-critical applications. The Shurflo by Pentair design reflects marine-grade engineering standards and serves as a first-line defense in raw water system protection protocols.
