Shurflo Twist-On Strainer, 1/2 Inch Pipe Inlet, 50 Mesh Stainless Steel Screen (255-313)

The Shurflo Twist-On Strainer (255-313) is a 1/2 inch pipe-inlet water strainer that screws directly onto the pumphead to keep debris and particles out of freshwater pump systems. Its clear, transparent housing lets you see at a glance when the bowl needs cleaning, so maintenance happens before the pump is starved or clogged rather than after a failure. Inside, a 50 mesh stainless steel screen catches sediment and small particulate while allowing water to flow freely to the pump.

The strainer is built from durable plastic housing components with a stainless steel exterior finish on the screen assembly, and it uses NPSM threads to mate with the pumphead. It disassembles easily for cleaning and reassembles just as quickly, so routine upkeep does not require tools or downtime. This is a compact, economical way to extend the service life of a freshwater pump by stopping debris before it reaches the impeller or valves.
