Shurflo Swivel Nut Fresh Water Strainer, 1/2 Inch Pipe Inlet, Clear Bowl, Part 255-315

The Shurflo Swivel Nut Fresh Water Strainer is a clear, twist-on inline strainer built to protect a fresh water demand pump from debris and particles that cause premature wear and unnecessary repairs. It features a 1/2 inch pipe inlet and screws directly onto the pump head using its swivel nut fitting, making installation straightforward without special tools. The clear, clean plastic bowl construction lets you see at a glance when the strainer needs cleaning, so maintenance is visual rather than guesswork.

Inside the bowl sits a 50 mesh stainless steel screen that catches sediment, sand, and other debris before it reaches the pump inlet, helping extend pump life and maintain consistent water flow. The strainer disassembles easily for cleaning and reassembles just as quickly, so routine upkeep takes only a few minutes. Its compact, lightweight design makes it suitable for tight installation spaces found in marine and RV fresh water systems.

This strainer is compatible with Shurflo demand pumps that use a 1/2 inch pipe (MPT) inlet connection. It is sold as a standalone strainer for use ahead of the pump inlet in a fresh water plumbing line.
