GEN2 Select-A-Seal® Rubber-Edged Composite Gasket
Perimeter Sealing Technology for Corrosion Mitigation

Adhesion + Compression = Superior Sealing Performance
Our composite sealing solutions for heavy duty agriculture and construction vehicles are engineered to stop corrosion from the perimeter of the application.
The innovative rubber edge prevents salt ingress, moisture, and contaminants from penetrating the barrier with protection that withstands environmental impact for up to 15 years.
Features and Benefits
- Warranty Performance
- Serviceability
- Lowest “load to seal” technology
- Environmentally Clean
- Corrosion Mitigation
- Prevalent in AL and Electric Drive Units
The Science Behind the Seal
GEN2 Select-A-Seal is engineered with Rubber Edge Construction (REC), a perimeter polymer edge specifically designed for demanding environmental applications.
Industry Challenges:
- Flanges will corrode due to saltwater exposure
- Traditional solutions including REM, RCM, Liquid, Foam and O-Rings can allow water migration.
Solution:
Perimeter Select-A-Seal polymer prevents moisture ingress and helps to eliminate corrosion migration.
Industrial Thermal Management Insulation
Millboard
Thermal Millboard for Refractory Applications
Interface millboards are 100% asbestos-free.
To meet the needs of the global iron and steel processing industries, and other industrial operations that require high-temperatures, Alkegen’s Interface Performance Materials offers three types of refractory millboard. 100% asbestos-free refractory materials are available for both continuous and “one shot” applications.

Millboard
Industrial Thermal Management Insulation.

412 Millboard Materials
412 millboard is a ceramic fiber board with inorganic fillers. It is an exceptional thermal insulator and is used for high temperature roll coverings and in fire protection areas where high strength properties are required. It is intended for applications with maximum continuous operating temperatures up to 1260°C (2300°F), and it resists melting up to 1760°C (3200°F).

1401 Millboard
1401 millboard is a high temperature material for use in gasketing, insulation, personal protection, heat and flame barriers, dryers, parting media and expansion joints. It is intended for use in applications with maximum continuous operating temperatures up to 1260°C (2300°F) and it resists melting up to 1760°C (3200°F).

RG30 Refractory
RG30 Millboard is manufactured with high purity ceramic fibers. It has the lowest shot content of our refractory millboard line. It is recommended for “one shot” applications such as casting process mold gaskets, for example, to 1482°C (2700°F).
