PEEK plug

PEEK plug

Core Features

  • High-Pressure Sealing Integrity: Engineered to provide a secure, leak-proof seal in hydraulic and fluidic systems, even under extreme internal pressures.
  • Thermal Expansion Matching: Maintains its sealing force and dimensional stability in continuous operating temperatures up to 250°C.
  • Total Chemical Immunity: Resistant to virtually all organic solvents, aggressive acids, and bases, preventing the plug from degrading or seizing in the port.
  • Precision Threading: Available with zero-defect NPT, Metric, or proprietary threading achieved through 5-axis CNC machining for a perfect mechanical fit.
  • Non-Conductive & Non-Magnetic: Acts as an excellent electrical insulator and does not interfere with magnetic fields, making it ideal for sensitive electronic or medical environments.

At Kriloha Ltd., we understand that in high-performance systems, a simple plug is often the only thing standing between operational success and a catastrophic leak. Our PEEK Plugs are our engineered answer for “Zero-Leak-Security” and “Environmental-Isolation”. As a premier provider of customized industrial solutions, Kriloha has developed a specialized fabrication division that translates complex mechanical requirements into high-performance sealing components.

The engineering of our plugs is founded on Structural-Rigidity and Sealing-Integrity. By utilizing state-of-the-art 5-axis CNC machining, we eliminate the structural inconsistencies and parting lines often found in standard molded plugs, ensuring perfectly uniform threads and seating surfaces. At Kriloha, we verify the dimensional stability of every bespoke plug under maximum thermal load, resulting in “Failure-Resistant” interfaces that do not warp or creep in high-heat environments.

Manufacturing these advanced polymer components involves strict Dimensional, Thermal, and Purity Verification. We collaborate directly with your engineering teams to process bespoke configurations—including integrated O-ring grooves, proprietary drive geometries (hex, slotted, or torx), and non-standard thread pitches. By choosing Kriloha Ltd., you are investing in a “Future-Proof” manufacturing partnership that optimizes your system’s reliability through superior material performance.

Primary Use Cases

  • Analytical Instrumentation: High-purity port plugs for HPLC, GC-MS, and other laboratory equipment where metallic contamination must be avoided.
  • Oil & Gas Downhole Tools: Ruggedized sealing plugs for electronic housings and logging tools exposed to corrosive geothermal fluids and high pressure.
  • Medical Diagnostic Devices: Non-magnetic and radiolucent plugs for fluidic manifolds in MRI and CT scanning hardware.
  • Semiconductor Manufacturing: Low-outgassing, high-purity plugs used in vacuum chambers and wet-etching stations to prevent particulate contamination.
  • Aerospace Fluid Systems: Lightweight, high-strength plugs for fuel and hydraulic manifolds designed to survive extreme thermal cycling.

Frequently Asked Questions

Why use a PEEK plug instead of Stainless Steel?

Metal plugs are heavy, prone to corrosion, and can seize in the port over time. PEEK provides the strength of a metal while being lightweight, chemically inert, and non-conductive, ensuring easy removal even after exposure to harsh environments.

Can Kriloha machine plugs with specialized internal O-ring grooves?

Absolutely. We specialize in precision CNC machining, allowing us to create exact groove geometries to match your proprietary sealing requirements for high-pressure or vacuum applications.

Is PEEK safe for high-pressure steam sterilization?

Yes. PEEK features phenomenal hydrolysis resistance, allowing it to withstand thousands of hours of high-pressure steam and boiling water without any loss of mechanical strength or shape.

How does PEEK handle high-vibration environments?

PEEK has excellent fatigue resistance and natural mechanical damping properties. Unlike metal, which can undergo work-hardening and crack under vibration, PEEK absorbs energy and maintains its integrity.

Are custom layouts available for non-standard port sizes?

Yes. We utilize precision CNC technology to achieve sub-millimeter accuracy for any custom diameter, thread type, or specialized geometry required by your proprietary CAD designs.
