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

Backup rings prevent extrusion and extend the service life of O-rings in high-pressure or wide-clearance sealing applications. Available in PTFE, nylon, and other durable materials, they ensure reliable performance in static and dynamic hydraulic or pneumatic systems.

Spiral vs Split PTFE Backup Rings | Choosing the Right Seal Solution

PTFE Teflon provides outstanding chemical resistance, low friction, and a broad operating temperature range. Commonly used for seals, bearings, and housings supporting O-rings and gaskets, it performs reliably in chemical processing, semiconductor, and industrial applications.

PTFE: Slicker than a Banana Peel

PTFE coatings provide an ultra-low friction surface with excellent chemical and temperature resistance. Commonly applied to O-rings, seals, and metal components, they reduce sticking, improve wear resistance, and enhance assembly performance.

PTFE Coated O-Rings: Benefits, Applications, and Maintenance

Spring energized seals (SES) combine a polymer sealing jacket, often PTFE or PEEK, with a metallic spring to maintain constant sealing force under varying pressures and temperatures. Used in place of O-rings and gaskets  in aerospace, cryogenic, and chemical processing applications, they provide exceptional wear, chemical, and extrusion resistance.
