PEEK Seals
High-Strength Sealing for Extreme Conditions
AccroSeal specializes in the production of PEEK (Polyether Ether Ketone) seals, engineered for demanding environments where standard polymers fall short. Known for their outstanding mechanical strength, chemical resistance, and thermal stability, PEEK seals are ideal for high-pressure, high-temperature, and high-load applications across critical industries.
Benefits of PEEK Seals
- Exceptional Strength & Rigidity: Withstands extreme loads and mechanical stress without deforming.
- High Temperature Resistance: Performs consistently in temperatures up to 480°F (250°C), with peak performance at intermittent exposure above that.
- Chemical & Hydrolysis Resistance: Resists harsh chemicals, steam, and high-purity cleaning agents.
- Wear & Abrasion Resistance: Ideal for dynamic sealing in rotating or reciprocating equipment.
- Creep and Fatigue Resistance: Maintains structural integrity under long-term stress and high-pressure applications.
PEEK Seal Applications
- Aerospace & Defense Systems: Used in actuators, valves, and fuel systems where durability is non-negotiable.
- Oil & Gas Exploration: Performs in aggressive downhole environments, including high-pressure and corrosive wells.
- Semiconductor & Electronics: Ultra-clean and thermally stable, suitable for plasma chambers and high-vacuum processes.
- Medical & Pharmaceutical Equipment: Biocompatible options available for surgical devices and fluid handling systems.
- Industrial Equipment: Seals in pumps, compressors, and valves for chemical processing or high-load mechanical systems.
Types of PEEK Seals We Offer
- Back-Up Rings & Wear Rings: Provide extrusion resistance in high-pressure hydraulic systems.
- Spring-Energized Seals: Combine PEEK’s durability with spring tension for high-performance sealing in extreme conditions.
- Rotary Seals & Valve Seats: Precision-machined for critical motion control and sealing accuracy.
- Custom Profiles: Machined to exact specifications from virgin or filled PEEK grades (carbon, glass, graphite, etc.).
Why Choose AccroSeal PEEK Seals?
We manufacture precision-machined PEEK seals in custom profiles, with tight tolerances and fast lead times. Our team partners closely with customers to ensure every seal meets the exact mechanical, thermal, and chemical requirements of your application.
