EVOLUTION® is a patented product that is the first of its kind to be a fully encapsulated isolating gasket. The thinner, 1/8” (3mm) design minimizes the difficulties often encountered while attempting to install thicker isolating gaskets. The total encapsulation allows the gasket to be hydro-tested and kept in the pipeline with virtually no loss in isolation properties.
This innovative gasket is coated using a GPT proprietary material designed specifically for the oil and gas industry that is extremely abrasion and impact resistant. The coating is also chemically resistant to attack from H₂S, steam, CO, CO₂, and other chemicals found in oil and gas pipelines.
EVOLUTION® has passed API 6FB fire testing in multiple sizes and pressure classes and has a considerable increase in operating temperature over GRE products. Furthermore, EVOLUTION® does not have the permeation issues or chemical attack that plagues GRE gaskets.
Under harsh conditions, gaskets made from GRE may be vulnerable to chemical attack, blowout, thermal attack, hydrolysis and emissions —all of which can have serious consequences. EVOLUTION® is different. Its revolutionary materials and design provides industry-leading resistance to leakage and flange corrosion, as well as unprecedented levels of fire safety.
Unlike GRE gaskets, which are prone to delamination, EVOLUTION® has no laminations and as a result can better withstand high-pressure environments.
Rated to 500°F (260°C)*, EVOLUTION® can also operate under high temperatures. Tested comprehensively for safety, the product has API 6FB, 3rd Edition Fire Test recognition.

Greenhouse gas reductions and carbon capture are hot topics and sure to be a focus of attention for years to come. Traditional GRE gaskets are made of epoxy and glass fiber. Gases travel very easily along the glass fibers making tight emissions difficult for GRE isolation gaskets. EVOLUTION has dual seals on the inside diameter with no use of GRE. This stops media from permeating at the source. Where a typical G10 with stainless steel core isolation gasket might leak 3 cc of helium per hour, EVOLUTION’s leak rate is only 1 cc of helium every 10,000 years on average!
Due to the extreme tightness of EVOLUTION, EVOLUTION is a viable sealing solutions for the transportation of GHG's( Methane, Halogens & C02) hydrogen, and LNG applications.
