66519 SnowEx / Blizzard / Western / Fisher Pump O-Ring 2-250

New 2-250 O-Ring #66519

This is a new 2-250 O-ring, part #66519, commonly used on the pump reservoirs of many Western, Fisher, SnowEx, and Blizzard plows. It has a 5-inch inside diameter.

This O-ring seals the connection between the fluid reservoir and the manifold assembly. It’s also included in several OEM filter kits, but can be purchased here individually as a replacement. A good seal is critical to preventing leaks and maintaining proper system pressure.
