4" Dielectric Steam Gasket

This 4-inch dielectric steam gasket from Legend Valve suits industrial piping systems that require electrical isolation between flanges. Maintenance crews and plant engineers specify it when steam lines must remain electrically separate to prevent galvanic corrosion or stray currents.

Replaces worn or missing dielectric gaskets

Swap this gasket in when an existing dielectric seal has degraded, leaked, or been lost during flange maintenance. The upgrade is worth it whenever the pipeline carries steam and the design calls for a non-conductive barrier between mating flanges.

Simple flange installation

Place the gasket between aligned flanges, insert bolts, and torque in a cross pattern to the specification for the flange class. Common issues include uneven bolt tightening that pinches one side, reusing old bolts that stretch, or mating surfaces that are pitted or contaminated.
