EVOLUTION®

The thinner, 1/8” (3mm) design minimizes the difficulties often encountered while attempting to install thicker isolating gaskets.

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.

Advanced Protective Coating

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.

Designed for Harsh Operating Conditions

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.

High Temperature Capability

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.
