About 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 are not reusable.

Copper washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

High-Temperature Steam-Resistant Metallic Pipe Gaskets

Gasket Shown with Flat-Surface Pipe Flange

Gasket Shown with Raised-Surface Pipe Flange

Corrugated

Smooth

Made of 110 copper, these gaskets handle steam applications up to 600° F. They are electrically conductive and resist water, Freon, and fuel oil. The metal construction provides structural strength. These gaskets can be used with both flat-surface and raised-surfaces pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection. Gaskets are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards.

Corrugated gaskets conform to rough and uneven surfaces when put under low pressure for a tight seal.

Smooth gaskets can withstand higher pressure than the corrugated gaskets.

EMI-Reducing Grounding Ribbon

Low resistance at radio frequencies reduces electromagnetic interference (EMI). The smooth, flat design provides more surface area contact than wire or braid. Polyester insulation prevents shorting. Use in circuit board applications and other tight spaces.
