Gasket Shown with a Raised-Surface Pipe Flange
Also known as spiral-wound gaskets, these have a 1/8” thick carbon steel outer ring and a 304 stainless steel sealing element with a graphite-based filler. 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 for ANSI class flanges are sized so all gasket specifications meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges. Gaskets for ANSI Class 600 flanges are compatible with high-pressure pipe flanges. Gaskets for ANSI Class 1500 flanges are compatible with extreme-pressure pipe flanges.
Gaskets for DIN flange sizes are sized to fit pressure class PN16 flanges.
Gaskets with an inner ring prevent flange errosion.

Gasket Shown with a Raised-Surface Pipe Flange
These gaskets have a 1/8” thick carbon steel outer ring and a 304 stainless steel inside sealing element with a PTFE filler. The PTFE is chemically inert (except to molten alkali metal and fluorine compounds). The metal construction provides structural strength. These gaskets, also known as spiral-wound 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. All gasket specifications are sized to meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.

Gasket Shown with a Raised-Surface Pipe Flange
A space between the outer ring and the sealing element prevents the element from being squeezed inward and contaminating the process line. Also known as spiral-wound gaskets, these have a 1/8” thick carbon steel outer ring and a 304 stainless steel sealing element with a graphite-based filler. The metal construction of these gaskets provides structural strength. They compensate for flange movement caused by vibration and pressure. These gaskets can be used on both flat-surface and raised-surface pipe flanges; they fit inside the bolt holes and do not interfere with the bolt connections. All gasket specifications are sized to meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.

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. Made of neoprene, the seal has good oil and abrasion resistance. Washers are reusable.
Hot-dipped galvanized steel washers are corrosion resistant in wet environments.
