PEEK Gaskets

_______________________________________________________________________________________________________________________________________________________________________

Polyetheretherketone (PEEK) gaskets represent the pinnacle of advanced polymer sealing technology, combining unparalleled thermal resilience, chemical inertness, and structural integrity. As semi-crystalline thermoplastics, PEEK gaskets maintain dimensional stability across extreme temperature ranges (-350°F to 480°F), outperforming traditional elastomers in high-pressure environments.

Engineered for critical applications, our PEEK seals feature:

Superior Temperature Tolerance: Operate continuously at 250°C (482°F) with short-term resistance up to 300°C (572°F).

Chemical Inertness: Resist degradation from hydrocarbons, steam, acids, and bases.

Mechanical Robustness: 4/5 wear resistance rating with low friction coefficients.

Custom Configurations: Available as backup rings, O-rings, lip seals, and anti-extrusion components.

Ideal for aerospace propulsion systems, oil & gas wellheads, semiconductor manufacturing, and medical sterilization equipment, our gaskets comply with FDA, UL-94, and RoHS standards. Compared to metal-reinforced Helicoflex seals, PEEK alternatives demonstrate equivalent vacuum integrity at 58mm diameters5 with 40% lower installation torque requirements, reducing surface damage risks on glass and metal interfaces.

Custom-engineered solutions include:

Reverse-engineered legacy seal replacements

Emergency 24-hour production turnaround

Material certifications for ISO 9001 environments

3D-printed prototypes for rapid testing

With helium permeation rates below 1×10⁻⁹ mbar·l/s at 200°C, our PEEK gaskets ensure leak-free performance in ultra-high vacuum (UHV) systems while providing electrical insulation critical for particle accelerators and fusion reactors.
