Core Features

  • High-Pressure Reliability: Specifically engineered to provide a robust mechanical seal in environments exceeding 10,000 PSI, resisting the “cold flow” and deformation typical of lower-grade polymers.
  • Dynamic and Static Versatility: Manufactured to serve as both static gaskets and high-speed dynamic seals, thanks to PEEK’s naturally low coefficient of friction and high wear resistance.
  • Thermal Load Security: Maintains absolute dimensional stability and sealing force in continuous operating temperatures up to 250°C (482°F).
  • Chemical and Corrosion Immunity: Resistant to virtually all aggressive industrial solvents, etching acids, and organic bases, ensuring zero degradation in corrosive fluid streams.
  • Micro-Tolerance Surface Finish: Utilizing precision 5-axis CNC machining to achieve exceptionally low Ra values (surface roughness), critical for achieving gas-tight seals.

At Kriloha Ltd., we recognize that in critical systems, the seal is the final line of defense against catastrophic failure. Our PEEK Seal Rings represent our engineered answer for “Zero-Leak-Security” and “Structural-Isolation-Integrity.” As a leading manufacturer of high-performance polymer solutions, Kriloha has established a specialized fabrication ecosystem designed to bridge the gap between complex engineering requirements and field-ready sealing performance.

The engineering of our seal ring program is founded on Material-Purity and Geometry-Precision. Unlike standard molded seals, our CNC-driven manufacturing process eliminates internal stresses and parting lines, ensuring a perfectly concentric and flat sealing face. At Kriloha, we verify the mechanical modulus and thermal expansion rates of every batch, resulting in “Failure-Resistant” rings that replace heavy, corrosive metal seals and outlive traditional PTFE alternatives.

Manufacturing these advanced polymer components involves strict Pressure-Testing, Thermal-Calibration, and Surface-Roughness Verification. We collaborate directly with your engineering teams to process bespoke configurations—including spring-energized jackets, specialized lip geometries, and reinforced PEEK grades (Carbon-Filled or PTFE-Lubricated). By choosing Kriloha Ltd., you are investing in a “Future-Proof” manufacturing partnership that prioritizes your system’s reliability through superior material science.

Primary Use Cases

  • Oil & Gas Exploration: Ruggedized seal rings for downhole logging tools and subsea wellhead equipment exposed to HPHT (High Pressure High Temperature) conditions.
  • Semiconductor Manufacturing: High-purity, low-outgassing seals for vacuum chambers and gas delivery systems where metallic contamination is prohibited.
  • Aerospace & Defense: Lightweight, high-strength seals for hydraulic actuators, fuel systems, and environmental control units in aircraft and satellites.
  • Medical & Life Sciences: Biocompatible and autoclave-safe seal rings used in surgical instruments, diagnostic hardware, and pharmaceutical mixing vats.
  • Automotive Precision: High-temperature sealing solutions for turbochargers, transmissions, and advanced braking systems.

Frequently Asked Questions

Why choose PEEK seal rings over traditional Elastomeric or PTFE seals?

Elastomers fail at high temperatures, and PTFE “creeps” under high pressure. PEEK provides the chemical resistance of PTFE but with the mechanical strength of metal, allowing it to maintain a seal under extreme pressures and temperatures without losing its shape.

Can Kriloha manufacture seal rings for dynamic (moving) applications?

Absolutely. PEEK’s high wear resistance and low friction make it ideal for rotary and reciprocating seals. We can also provide PTFE-filled PEEK grades to further reduce friction and heat buildup in high-speed applications.

Is PEEK safe for seal rings in high-vacuum environments?

Yes. PEEK has exceptionally low outgassing rates and does not shed particulates, making it the industry standard for semiconductor and aerospace vacuum systems where purity is critical.

How does Kriloha ensure a leak-proof fit for custom dimensions?

We utilize 5-axis CNC machining to achieve sub-millimeter tolerances. By matching the seal ring’s geometry to your specific housing dimensions and mating surface finish, we ensure a perfect mechanical interface.

Are Kriloha PEEK seal rings compatible with aggressive chemicals?

Yes. PEEK is chemically inert to almost all organic and inorganic chemicals, including hydrogen sulfide, steam, and aggressive acids, ensuring the seal remains effective in the harshest industrial environments.
