Insulation Gasket
Asian Sealing Products offers high-performance insulation gaskets to prevent corrosion and ensure electrical isolation in demanding industrial applications.
Insulation gaskets are essential in flanged connections, particularly those involving dissimilar metals. They create a physical barrier to electrically isolate the flanges and prevent galvanic corrosion. This destructive process occurs when two metals with different electrical potentials come into contact in a corrosive environment. Asian Sealing Products’ insulation gaskets offer a reliable solution to this costly problem.

Product Details
TYPE E (Full Face Type Gasket)
- Provides complete protection for both flange faces
- Comes with the same outside diameter of the flanges. Hence, the foreign material collection between the flange faces is prevented
- Ensures complete cathodic isolation
- The E gaskets are available in Plain faced Phenolic, Neoprene faced Phenolic and high temperature material like G-10
Type F (Raised Face Type Gasket)
- Designed to fit only onto the raised face surface of the flanges
- Outside diameter of the gasket is slightly lesser than the inside diameter of bolt circle
- For best results, the flanges must be wrapped with Flange Band Protectors. So foreign materials are prevented from collecting and creating a bridge, thus shorting out the isolation
- Available in same material as Type E
Type D (RTJ Type Gaskets)
- Designed to fit into the ring groove of RTJ flanges
- Available in Phenolic and G10 material types
G10 / G11 with viton / Spring energised Gaskets
- We use a machined glass-reinforced epoxy (GRE) resin with an O-ring or spring energised seal to produce this insulation set
- These gaskets can be used for flange ratings from class 150 to 600
- Improvises compressive strength over conventional insulation sets
- Provides greater resistance to over compression and cracking
Metal Core with G10 / G11 Gaskets
- Highly reliable for both insulating and general sealing purposes in critical services
- These gaskets have a proven track record of integrity in aggressive sealing situations
- Suitable in all services up to and including ANSI 2500# and API 15,000# classes
- Metal Core with G10/G11 gaskets consists of a PTFE (Teflon) spring-energized face seal, or an elastomeric o-ring
- Accommodated in an insulating laminate that is permanently bonded to a high-strength metal gasket core
How Insulation Gaskets Work
Asian Sealing Products’ insulation gaskets are meticulously crafted from non-conductive materials, creating a physical barrier between the flanges. This barrier disrupts electrical continuity, preventing current flow and halting galvanic corrosion. Additionally, some gasket materials incorporate corrosion-inhibiting agents, further protecting the connected components.

Answers to all your possible questions.
What is a Flange Gasket ?
A flange gasket is a mechanical seal used to fill the space between two flanges in order to prevent leakage from or into the joined objects while under compression. Flanges are components used to connect pipes, valves, pumps, and other equipment in various industries such as oil and gas, chemical processing, water treatment, and more. Flange connections are widely used because they provide a secure and leak-resistant joint between two separate components.
What industries benefit from flange insulation gasket kits?
Flange insulation gasket kits are widely used in industries such as oil and gas, petrochemicals, chemical processing, power generation, water treatment, and offshore installations.
How does a flange insulation kit work?
A flange insulation kit functions by forming a barrier between the flange faces. It separates the flange components with insulating gaskets and sleeves, providing both physical and electrical insulation.
How thick is an insulating gasket?
The manufacturer usually specifies the thickness, but it can be customized to meet the specific needs of the project. Insulating gasket thicknesses can range from 1/16 inch (1.6 mm) to 1/4 inch (6.4 mm) or even thicker in some cases.
How do F, E, D, and O gasket isolation kits differ?
F, E, D, and O gasket isolation kits differ in terms of their design and construction- the geometry, materials, and thickness of the insulating components. Each type is designed to meet specific industry standards and requirements, with varying levels of electrical insulation and corrosion resistance.
Which gasket isolation kit should I choose?
The choice of gasket isolation kit depends on factors such as flange size, pressure rating, and the specific requirements of the application. It is advisable to consult with the manufacturer or supplier to determine the most suitable kit for your specific needs.
