Flange Washer Gasket Sealing Insulation Kits

Each insulation kit is a comprehensive solution engineered to maintain electrical isolation and prevent galvanic corrosion in bolted flange connections. Every kit is composed of a precision-machined insulating gasket—either a ring-type (Type F) or full-face (Type E) design—customized to match the flange’s inner or outer diameter. These gaskets are manufactured from high-performance phenolic or G10 epoxy glass materials, and optionally feature corrosion-inhibiting facings that enhance chemical resistance and ensure fire-safe service. Designed to withstand aggressive environments such as offshore, chemical processing, and oil & gas installations, the gaskets ensure exceptional sealing performance even under extreme pressure and temperature conditions.

The kits also include seamless full-length insulating sleeves and isolating washer sets made from high-compressive-strength GRE (Glass Reinforced Epoxy) or phenolic laminate. These components are CNC-machined to tight tolerances to maintain bolt-circle alignment and uniform load distribution across the flange. SAE-plated steel washers are provided to prevent damage from nut torque and enhance mechanical integrity. Each kit is clearly labeled with the corresponding flange size, pressure rating, and washer type, and comes with detailed torque-sequence instructions to facilitate proper installation. The result is a durable and efficient flange insulation solution that ensures long-term reliability and system integrity.
