Benefits of Perlast® O-rings

Perlast® G77X is a unique FFKM elastomer that marks a step-change for critical O-rings, benefits for mechanical seal manufacturers and operators include:
  • Improved reliability
  • Optimal performance across wide temperature range
  • Increased operational life-time
  • Extended maintenance cycles
  • Reduced cost of ownership
  • Operational safety
 

Lowest compression set

In independant testing Perlast® G77X is able to maintain a sealing force
>50% for 260 hours at 300oC vs Competitor A which drops
below 50% after 170 hours.
 

This demonstrates the superior long-term durability of Perlast® G77X,
which extends maintenance intervals, and reduces costs and downtime.
