Johnson Pump Universal Strainer - 20 Mesh Screen

The Johnson Pump Universal Strainer with 20 Mesh Screen is an essential inline filtration component designed for marine engine cooling and raw-water intake systems. Built for mechanics and boat owners who demand reliability, this universal strainer protects pump impellers and heat exchangers from debris, sediment, and biological matter that can compromise system performance or cause catastrophic failure. The transparent housing allows quick visual inspection without breaking connections, making routine maintenance faster and less intrusive to your engine bay setup.

The 20-mesh screen size filters particles down to approximately 850 microns—coarse enough to maintain adequate flow rate while fine enough to catch sand, shell fragments, and organic debris common in salt and brackish water environments. Johnson Pump's KlickTite port connectors enable tool-free installation and removal, reducing downtime when you need to service or replace the mesh screen. The strainer body is manufactured from durable materials rated for marine duty, with the transparent cover engineered for inspection clarity and impact resistance. Weight of 0.6 lbs and compact 5 x 5 x 5 inch dimensions make this unit easy to mount in confined engine compartments where space is premium.

Mechanics upgrading raw-water cooling systems on inboard or outboard marine engines will find this universal strainer compatible with standard hose barb and quick-disconnect configurations. The PUMProtector designation signals Johnson Pump's commitment to inlet protection—critical for any cooling loop pulling from lakes, rivers, or coastal waters where pump cavitation or impeller damage can escalate minor debris into expensive repairs. Install this unit upstream of your main cooling pump as part of preventive maintenance on new builds or system refurbishment, and inspect the mesh quarterly in heavy-use seasons or after extended idle periods when settled sediment may have accumulated.
