Firesafe Gasket Kits

Overview

The Step-Ko SSCFS (Fire-Safe) gasket enhances the typical SSC design by incorporating a secondary sealing element that effectively maintains its seal even in temperatures reaching 1500°F (815°C) during a fire. This fire resistant gasket provides a reliable sealing performance in harsh conditions and successfully meets the requirements of the API 6FB, 3rd Edition fire test.

Features

  • With its innovative pressure-activated sealing mechanism, this heat-resistant gasket significantly reduces the necessary bolt stress for an effective seal compared to other gasket types.

  • The engineered secondary ring provides a reliable secondary seal during regular operation and transforms into the primary sealing solution in the event of a fire.

  • SSCFS Gasket

  • Hardened Coated Steel washers

  • G10 Bolt Sleeves

Additional Features

  • An isolating and sealing gasket, SSCFS Type “F”, comes with a 316 stainless steel core retainer that is laminated on both surfaces with a G-10 fiberglass reinforced composite.

  • It has a precisely tapered groove designed for the controlled compression of a PTFE spring-energized seal.

  • A secondary groove houses a carbon steel backup ring featuring a specialized isolating coating.

Engineered Survival Under Extreme Heat with a fire resistant gasket

A properly designed fire resistant gasket is critical in applications where sealing integrity must be maintained even during catastrophic temperature exposure. Built to withstand fire conditions exceeding 1500°F, this advanced sealing solution preserves joint stability when conventional materials fail. Its pressure-activated sealing mechanism allows consistent performance during normal operation while automatically adapting under extreme heat. By combining reinforced composite materials with precision machining, it delivers dependable isolation and sealing in high-risk industrial environments.

Performance You Can Trust from a Certified fire resistant gasket

A high-performance fire resistant gasket must maintain structural integrity before, during, and after exposure to fire conditions. Engineered with a dual-seal design and reinforced core structure, it ensures reliable performance under severe stress.

  • Maintains seal integrity during high-temperature fire events

  • Incorporates a pressure-energized secondary sealing element-free

  • Reduces required bolt stress compared to conventional gasket types

  • Meets rigorous API fire test standards for critical service

This engineered approach ensures uninterrupted protection in extreme service applications.

Frequently Asked Questions

1. What temperatures can advanced fire-rated sealing systems withstand?

Certain engineered designs are capable of maintaining sealing integrity at temperatures exceeding 1500°F during fire exposure.

2. How does a dual-seal design improve safety?

The secondary sealing element activates under extreme heat, providing backup protection when primary components are compromised.

3. Why is bolt stress reduction important in sealing systems?

Lower bolt stress reduces flange distortion and helps maintain consistent compression during thermal cycling.

4. Are these sealing systems suitable for high-pressure applications?

Yes, they are engineered to withstand significant internal pressures while maintaining structural stability.

5. What industries require fire-rated sealing components?

Oil and gas, petrochemical processing, refining, and power generation facilities frequently rely on these systems.

6. How do reinforced cores improve performance?

Reinforced cores prevent material collapse under compression and maintain dimensional stability in extreme conditions.

7. Do fire-rated gaskets support electrical isolation?

Certain engineered designs incorporate materials that also provide dielectric separation in corrosion control systems.
