PEEK Spring Energized Seals for Demanding High - Pressure & High - Temperature Uses
High - Performance Sealing via PEEK's Superior Properties
Our PEEK Spring Energized Seals are built for tough industrial use, pairing high-grade PEEK’s strengths with a spring-energized design for reliable, long-lasting sealing. PEEK delivers exceptional heat resistance, chemical inertness (against oils, solvents, harsh fluids), and wear resistance—ensuring durability under friction or pressure.
The integrated spring boosts sealing contact, adapting to minor surface flaws and maintaining tight seals in high-pressure setups like hydraulic systems or industrial machinery. Ideal for high-temperature or chemical-handling applications, these seals cut leakage risks, reduce maintenance, and support steady efficiency, making them a premium choice for critical, extreme-condition uses.

1. Product Advantages
Our PEEK Spring Energized Seals stand out with industry-leading performance, driven by high-grade PEEK material and precision engineering:
- Extreme Environmental Resistance: Withstand temperatures up to 260°C (500°F) and resist corrosion from oils, solvents, acids, and harsh industrial fluids—ideal for aggressive working conditions.
- Long-Lasting Durability: PEEK’s inherent wear resistance minimizes damage from friction or pressure cycles, extending seal lifespan and reducing replacement frequency.
- Reliable Sealing Under Pressure: The integrated spring mechanism adapts to minor surface irregularities (e.g., scratches on hardware) and maintains consistent contact, eliminating leakage even in high-pressure systems (up to 30,000 psi).
- Low Maintenance: Stable chemical and physical properties reduce downtime for inspections or replacements, lowering overall operational costs.
2. Working Principle
The seal operates through a synergistic design of PEEK material and a spring core:
- Spring Activation: A corrosion-resistant metal spring (e.g., Inconel, stainless steel) is embedded within the PEEK seal body. When installed, the spring exerts constant radial or axial force to press the PEEK lip against the mating surface.
- PEEK Sealing Interface: The PEEK material—with its low friction coefficient and high rigidity—forms a tight, leak-proof barrier between two components (e.g., cylinder rods and housings).
- Adaptability: Under dynamic conditions (e.g., movement, pressure fluctuations), the spring compensates for wear, thermal expansion, or surface imperfections, ensuring continuous sealing performance.

4. Application Range
Our PEEK Spring Energized Seals are trusted across industries requiring high-performance sealing:
- Oil & Gas: Downhole tools, wellhead equipment, and pipeline valves (resists crude oil, drilling fluids, and high temperatures).
- Aerospace & Defense: Hydraulic systems in aircraft, missile components, and engine seals (withstands extreme pressure and temperature shifts).
- Automotive: High-performance engine parts, transmission systems, and EV battery cooling circuits.
- Medical & Pharmaceutical: Sterilizable equipment (e.g., autoclaves) and fluid handling systems (FDA-grade PEEK ensures biocompatibility).
- Industrial Machinery: Hydraulic presses, injection molding machines, and chemical processing pumps (resists solvents and heavy-duty use).
5. FAQ
Q1: Can the seal be customized for non-standard sizes or special environments?
A: Yes. Forever Seals offers fully customizable solutions—including size, spring material, and PEEK grades (e.g., glass-filled PEEK for extra rigidity)—to meet unique application needs (e.g., ultra-low temperatures or toxic chemical exposure).
Q2: How do I choose the right spring material for my application?
A: Our team recommends materials based on your environment: Inconel 718 for extreme heat/corrosion, 316L stainless steel for general industrial use, and Hastelloy for strong acid resistance. Contact our engineers for personalized guidance.
Q3: What is the typical lifespan of these seals?
A: Under normal operating conditions (e.g., 150°C, 10,000 psi), the seals last 2-5 years—2-3x longer than standard elastomer seals. Lifespan may vary based on usage intensity and maintenance.
Q4: Are samples available for testing?
A: Absolutely. We provide free samples (up to 2 units) for qualified customers to validate performance in their specific setups.
