Flange Isolation Gasket Kits

Sealing and Isolation Solutions for Flanged Connections

Eliminating Metal to Metal Contact and Providing Electrical Isolation for Cathodic Protection

The Step-Ko Products Flange Isolation Gasket Kits are designed to maintain the integrity and reliability of the pipeline and piping system thorough safety and corrosion protection. Flange Isolation Gasket Kits provide both an effective seal and reliable electrical isolation of flanges. By eliminating metal to metal contact, static current is halted to prevent corrosion and aid in the Cathodic Protection of the piping system.

Constructed of high quality materials that have a high dielectric constant and low water absorption, our Flange Isolation Gasket Kits are available in various configurations to meet every possible need.

We offer Flange Isolation Gasket Kits in all sizes, ranging from 1/2″ to 144″, in all Ansi and API classes. Custom and special sizes are also available upon request.

At Step-Ko, we understand the importance of corrosion prevention in maintaining pipeline integrity, and we have designed our Flange Isolation Gasket Kits to ensure the reliability and safety of pipelines and piping systems.

Pipeline corrosion is most commonly a result of pipeline leakage or electrical currents between flanges at the connection’s seal. Gaskets are essential to preventing both of these problems on any pipeline, and Step-ko’s Flange Isolation Gasket Kits work to prevent corrosion by addressing both causes.

They are constructed of high-quality materials that have low water absorption to prevent leakage and ensure a proper seal.They are also made of a high dielectric constant to assist in electrical isolation of the flanges to eliminate the static current that is caused by metal to metal contact, aiding in the cathodic protection of the piping system.   

Designing a high-quality product is only a part of our job. Delivering it to our customers as quickly as possible is just as crucial. We understand the frustration that comes with waiting for the essential parts required to do a job. With inventory in warehouses across the country, we can ensure customers receive their Flange Isolation Gasket Kits when they need them.

As a leading provider of corrosion protection solutions, we have always maintained that our job is to help our customers protect their pipes, no matter the industry. We work with customers in the oil and gas, chemical, wastewater and other industries that depend on pipelines to move their resources. We work side-by-side with our customers to ensure they get the products they need.

To that end, our kits are available in various configurations and sizes, ranging from ½” to 144”, in all ANSI and API classes. Each kit contains gaskets, sleeves and washers. We can also provide customized Flange Isolation Gasket Kits to suit our customers’ special size and need requirements.

Don’t wait until it’s too late. Make Step-Ko’s Flange Isolation Gasket Kits an essential part of your flanged pipeline connections.

Flange Gasket Kit Types

flange isolation gasket kit type dType D

Type D gaskets are designed to fit into the ring groove of RTJ(ring type joint) flanges. We also offer BX gaskets. Both are available in grade CR phenolic.

flange isolation gasket kit type eType E

This style kit contains a full face gasket that has the same outside diameter as the flanges. This style gasket will prevent foriegn material from collecting and creating a bridge, thus shorting the cathodic isolation. Type E gaskets are available in phenolic, neoprene-faced phenolic, and high temperature materials.

flange isolation gasket kit type fType F

This gasket will fit only the raised face surface of the flanges. The outside diameter of the gasket is slightly less than the inside diameter of the bolt circle. This gasket can be used on both raised face and full face flanges. It is recommended that the flanges are wrapped with Flange Band Protectors to prevent foreign material from collecting and creating a bridge, thus shorting out the isolation. Type F gaskets are available in same material as Type E.

This gasket has a sealing element on each side and is available in both Type E and Type F styles. The sealing element materials are nitrile, viton, or Teflon. Gasket materials available are phenolic and G-10.
