Phenolic Flange Isolation Gasket

The gasket has excellent insulating properties, ensures cathodic protection and a very low leak rate.

Welcome to Learning About Phenolic Flange Isolation Gasket

The phenolic flange isolation gasket helps the pipeline and piping system work correctly by keeping electricity from passing through and protecting against corrosion. It offers an effective seal, electrical isolation, and corrosion protection for flanges. By removing metal-to-metal contact, we reduce corrosion and improve the cathodic protection of the pipe.

Available Types

Type E is full-faced, while Type F is raised.

Advantages

The phenolic flange isolation gasket is a particularly effective choice for non-potable water applications and non-metallic flanges.

Applications

It is suitable for non-potable water, utility gas applications, and aliphatic hydrocarbons.
