Shurflo Fresh Water Swivel Nut Strainer 1/2 Inch Barb Inlet, Part 255-325

The Shurflo Fresh Water Swivel Nut Strainer (part 255-325) is a 1/2 inch barb inlet strainer that protects freshwater pump systems by keeping debris and particles out of the pump. It is built for industrial and marine use and is CE listed. The strainer screws directly onto the pump head, and its swivel nut design lets you rotate and orient the outlet hose before tightening, which makes alignment and installation easier than a fixed twist-on strainer.

Inside the clear plastic housing is a 50 mesh stainless steel screen that catches sediment and debris before it can reach and damage the pump. The transparent bowl construction means you can see at a glance when the screen needs cleaning, without having to disassemble the unit to check. When cleaning is needed, the strainer disassembles easily for cleaning and reassembles just as easily, so maintenance takes only a few minutes.

The inlet port is a 1/2 inch barb straight fitting, and the outlet port is a 1/2 inch NPT connection secured with a hex wing nut for tool-free tightening. The unit is rated to a maximum temperature of 120 degrees Fahrenheit, making it suitable for typical RV and marine freshwater pump plumbing.
