Permeation occurs when gas or liquid molecules diffuse through an elastomer, potentially leading to pressure loss or contamination. Selecting low-permeation O-rings and gaskets made from materials like FKM, FFKM, or PTFE minimizes leakage and ensures long-term sealing performance in vacuum, fuel, and chemical systems.

Permeation and Outgassing in Seals

Spring-energized seals use a metal spring inside a PTFE or PEEK jacket to maintain consistent sealing pressure across temperature and pressure changes. Commonly used in place of O-rings and gaskets for extreme environments, they provide excellent chemical resistance, low friction, and long service life in aerospace, cryogenic, and chemical processing applications.

Spring-Energized Seal vs O-Ring | When to Upgrade, Extreme Conditions

Low-temperature seals maintain flexibility and sealing integrity in extreme cold conditions. Made from materials like silicone, fluorosilicone, and low-temperature FKM, these O-rings and gaskets perform reliably in aerospace, cryogenic, and industrial systems.
