PowerSeal Solutions™ is pleased to announce our new line of Marman Seals and Couplings that offer exceptional reliability and STOP LEAKS.

Our B-SureSeal™ Marman Seals are injection molded without any fillers, offering a pure and high-precision fit with true reliability. Made with new FKM and Viton® compounds, these seals have exceptional chemical resistance and improved performance over the competition.

Per ASTM D412-16 and D2240-15 testing, the PowerSeal B-SureSeal™ Marman Seals have greater tensile strength, superior elongation characteristics, and half of the compression
set when compared to other seals on the market.

This independent laboratory testing has shown the PowerSeal B-SureSeal™ Marman Seals to have improved physical properties, which directly translates into improved performance.

  • Made with pure FKM and Viton® A-type Family material – NO fillers
  • Injection molded for pure and high-precision fit with true reliability
  • Superior performance through operating temperatures from -20°F to +400°F
  • Resistance to oil, fuel, and additives
  • Remains flexible in service and won’t “set” like standard seals

PowerRail also offers a full line of Marman Couplings and upgraded Viton® Power (High Temperature) Seals.
