Guardian

The Guardian is a high-performance flange isolation gasket engineered for the most demanding critical-service applications. It delivers absolute electrical isolation and unmatched long-term corrosion control in aggressive hydrocarbon environments—protecting your assets where failure isn't an option.

Built with a 316/316L stainless steel inner core laminated on both sides with high-strength NEMA-grade G-10 or G-11 glass-reinforced epoxy (GRE), the Guardian resists deformation under extreme loads while ensuring superior dielectric strength and reliability.

Ideal for pipelines handling water, wastewater, natural gas, crude oil, H₂S, CO₂, refined hydrocarbons, LNG, and produced water at continuous temperatures up to 392°F (200°C).

Key Features & Benefits

  • Superior Construction: 316L stainless steel core with GRE laminations for exceptional compressive strength and creep resistance. Multiple core options available dependent on media and application.

  • Customizable Seals: PTFE, Viton, or application-specific elastomer O-rings

  • Full Electrical Isolation: Prevents galvanic corrosion between dissimilar flanges (>800 V/mil dielectric strength)

  • Extreme Durability: Handles vibration, thermal cycling, pressure fluctuations, and high bolt loads

  • Leak-Proof Performance: Minimizes fugitive emissions and eliminates fluid entrapment in RTJ flanges

  • Broad Compatibility: Flat Face (FF), Raised Face (RF), and Ring Type Joint (RTJ) flanges; Type E and Type F configurations

  • Wide Range: Sizes ½″ to 48″; Pressure ratings ANSI 150–2500 lb, API 6A/6B up to 15,000 psi, and more (matches ANSI, ASME, API, MSS, BS, DIN, AS standards)

Proven Worldwide Performance

Field-tested in upstream, midstream, and downstream operations globally, the Guardian stands guard under extreme pressure, temperature cycling, and mechanical stress—reducing maintenance, downtime, and risks.
