Insulating gasket kit FIK Drain
Dielectric insulation and effective sealing
The flange insulation kit, combined with the safety flange cover MSC Drain Flex - V2, guarantees optimal dielectric insulation, cathodic protection and an effective sealing of the flanged joint, contributing to the safety of the system and environmental protection by preventing the formation of galvanic currents.
Flange guards such as MSC Drain Flex - V2 represent the ideal solution when flanges are made of dissimilar materials (e.g., stainless steel and carbon steel). Due to their electrical insulation properties, these flange guards not only prevent accidental leaks, but also act as a dielectric barrier, minimizing the risk of galvanic corrosion on the less noble flange, typically carbon steel.
However, traditional gaskets used in flanged joints, such as spiral wound or reinforced graphite gaskets, do not offer sufficient dielectric insulation. Therefore, integration with the MSC Drain Flex - V2 flange cover becomes an essential solution for full system protection.

Applications
Reactors, tanks, and cryogenic lines (LNG, hydrogen): systems handling liquefied gases or hydrogen, where each component must ensure absolute reliability.
Gas pumping stations and pipelines: for electrically isolating pipeline sections and protecting flanged joints from accidental discharges, with the dual benefit of safety and leakage containment.
Chemical processing plants: process lines transporting aggressive fluids, to prevent leaks and protect metals from stray currents and galvanic corrosion.
The kit includes:
| Safety flange cover (1 pc): | Metal Spray Control / Drain Flex Made of stainless steel and designed to ensure maximum fluid sealing. It features an expanded PTFE tape gasket that provides effective dielectric insulation and prevents the leakage of fluids or gases. Its modular and flexible structure allows for easy installation, making it ideal for plants where aggressive fluids or galvanic differences between materials are present. |
| Insulating gasket (1 pc): | Composite gasket in AISI 321 stainless steel (Duplex or Alloy steels available upon request) coated on both sides with a layer of virgin Fluorton PTFE. The actual sealing is provided by a camprofile profile coated in virgin Fluorton PTFE. This gasket’s special feature, thanks to its excellent mechanical resistance and unique design, also allows installation on ring joint flanges (R, BX, or RX) without the need for subsequent modifications or adjustments to the kit structure. |
| Isolating sleeve (1 per bolt): | virgin Fluorton PTFE |
| Isolating washers (2 per bolt): | virgin Fluorton PTFE |
| Protective washers (2 per bolt): | HCS |
