About Washers

Washers

Pressure-Rated Metal-Bonded Sealing Washers

These washers are rated to maintain their seal under pressure.

Metal-Bonded Sealing Washers

Create a stronger seal than metal or rubber alone. These one-piece washers are metal for strength with a bonded rubber seal that creates a tight grip.

Rubber and Plastic Sealing Washers

Rubber and plastic washers resist water, oil, weather, and/or chemicals to create a light duty seal on your joints and damp vibration.

Metal Sealing Washers

Also known as crush washers, these compress when tightened to form a tighter, more durable seal than rubber washers. They are commonly used to seal fluids such as oil and fuel.

Washers

Cushioning Washers

Cushion joints to damp vibration and protect from wear.

Fastener Kits for Enclosures

Fastener Kits for Enclosures

Mount components to your enclosure without worrying about leaks—these kits seal out water from washdowns, rain, and snow when used with enclosures rated NEMA 4X.
