Groco WSB-500 Inline Fresh Water Strainer 1/2" NPT Ports with #304 SS Basket and Mounting Bracket

The Groco WSB-500 is a 1/2" inline fresh water strainer designed to protect onboard fresh water pumps from debris that can cause costly damage and premature wear. Built for above-waterline installation, this compact strainer features a white nylon strainer head and a clear plastic sight glass that allows for quick visual inspection without removing the unit from the line.

Key Features:

• #304 stainless steel 20-mesh basket — recommended for fresh water applications
• Clear plastic sight glass unscrews easily for tool-free filter basket removal and cleaning
• 1/2" female NPT inlet and outlet ports for straightforward plumbing integration
• White nylon body construction — lightweight, corrosion-resistant, and durable
• Mounting bracket included — mounts securely in a vertical orientation for optimal flow and serviceability
• For use above the waterline only

The WSB-500 is the standard fresh water model in Groco's WSB series, featuring a #304 SS basket suited for fresh water systems.
