Perlast® G75LT

Perlast® G75LT – Performance at Extremely Low Temperatures

Perlast® G75LT is one of the Perlast® Super-Six range of outstanding FFKM compounds. It presents a distinctive blend of outstanding chemical resistance and remarkable low-temperature performance. Tailored for extreme conditions, it remains effective even in temperatures as frigid as -46°C (-51°F). Furthermore, this perfluoroelastomer is engineered to withstand a wide array of chemicals by precisely managing its molecular structure.

With low permeability, Perlast® G75LT resists swelling, ensuring prolonged performance in valves, pumps, and mechanical seals. It’s particularly well-suited for exploration and completion applications, as well as equipment operating or stored in sub-zero conditions. Capable of fulfilling both dynamic and static roles, it can be seamlessly molded into O Rings (up to 2.5m/8ft internal diameter) and customised shapes to suit various needs.
