Insulation Gasket

A complete Insulation Kit from Asian Sealing Products is designed to offer everything needed for effective flange isolation and corrosion protection in one convenient package. Each kit is engineered for performance, reliability, and ease of installation.

The standard insulation kit includes:

• Insulating Gasket
  Precision-engineered to provide optimal sealing and electrical isolation between flanges. 
• Insulating Sleeves
  Non-conductive sleeves that cover the bolts, preventing metal-to-metal contact. 
• Insulating Washers
  High-strength, non-conductive washers placed on either side of the flange to maintain isolation. 
• Metal Backup Washers
  Provide mechanical strength and support to the insulating washers during tightening. 

Each component is manufactured using high-quality, corrosion-resistant materials such as G10, G11, PTFE, and epoxy-coated metals. Kits are available in various types (Type F, E, and D) and can be customized to match ANSI, DIN, and other flange specifications.

With Asian Sealing Products’ Insulation Kits, you get a complete, ready-to-install solution for long-lasting performance and protection in critical sealing applications.

• Complete electrical isolation
• Enhanced sealing coverage across the entire flange face, including flange bolts
• Prevents flange face corrosion and fluid leakage
• Comes with the same outside diameter as the flanges. Hence, the foreign material collection between the flange faces is prevented
• Ideal for high-pressure and corrosive environments
• Suitable for flat face and raised face flanges
• The E gaskets are available in plain-faced Phenolic, Neoprene-faced Phenolic, and high temperature material like G-10 that offer excellent mechanical strength, chemical resistance, and thermal stability.

Choose TYPE E when your application demands maximum coverage and comprehensive isolation protection.

• Designed to fit only the raised face area of flanges
• Provides reliable sealing and electrical insulation
• The outside diameter of the gasket is slightly less than the inside diameter of the 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
• Ideal for high-pressure pipeline systems
• Prevents galvanic corrosion between dissimilar metals

Choose TYPE F Insulation Gaskets when you need a compact, high-efficiency sealing solution tailored for raised face flange designs.

• Precisely fits RTJ flange grooves for optimal sealing
• Provides strong electrical insulation and mechanical strength
• Ideal for extreme pressure and temperature environments
• Prevents leakage and flange corrosion
• Available in Phenolic and G10 material types
• Suitable for critical oil & gas, petrochemical, and power industry applications

For a robust, leak-proof, and electrically isolating solution in RTJ flange systems, TYPE D Insulation Gaskets deliver trusted performance and durability.

• G10/G11: High-pressure insulating laminates known for their mechanical strength, thermal stability, and excellent electrical insulation.
• Viton: A fluoroelastomer known for exceptional resistance to chemicals, oils, and heat, enhancing gasket durability and sealing capability.
• Spring Energized Gaskets incorporate a flexible metallic spring core wrapped with a resilient sealing material such as PTFE or elastomers. This design maintains consistent sealing force even under fluctuating temperatures and pressures, ensuring leak-tight performance in dynamic conditions.

Features-

• Maintains strong sealing force over a wide temperature range
• Excellent chemical and abrasion resistance
• We use a machined glass-reinforced epoxy (GRE) resin with an O-ring or spring-energized seal to produce this insulation set
• These gaskets can be used for flange ratings from class 150 to 600
• Improves compressive strength over conventional insulation sets
• Provides greater resistance to over-compression and cracking
• Ideal for applications with thermal cycling and mechanical vibrations
• Provides long service life and reliable sealing in demanding conditions

Metal Core Gaskets with G10/G11 Insulation combine the mechanical strength of a robust metal core with the excellent electrical insulation and chemical resistance of G10 or G11 laminate materials. The metal core provides structural support, ensuring the gasket maintains its shape and withstands high pressure and mechanical stress, while the G10/G11 layers prevent galvanic corrosion by electrically isolating flanged connections.

Features:

• Strong metal core for enhanced mechanical stability
• High-quality G10/G11 insulation for excellent electrical isolation
• Resistant to chemicals, heat, and pressure
• Prevents galvanic corrosion in flanged joints with dissimilar metals
• Suitable for harsh environments including oil & gas, petrochemical, and power industries
• 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 for 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.
