Gas Spring Seals

KOK designs and manufactures gas spring seals for automotive and industrial applications requiring controlled dynamic performance and long-term sealing reliability.

Gas spring seals operate under repeated rod movement and internal pressurization, where low breakaway force, stable dynamic friction, and consistent sealing integrity are essential to predictable gas spring performance.

Engineering & Functional Performance

KOK gas spring seals are developed according to defined customer specifications, with attention to:

• Controlled static sealing to prevent pressure loss
• Stable dynamic friction characteristics
• Resistance to wear against plated or hardened rod surfaces
• Long-term dimensional stability under cyclic loading

Seal geometry and material formulation are aligned with operating pressure, stroke length, rod finish, and environmental exposure.

Material selection and compound tuning are performed based on application requirements and operating conditions.

Dimensional Range

Rod Diameter Range: 4 mm – 30 mm

Custom profiles and dimensions are supported based on customer-provided drawings.

Application Scope

KOK gas spring seals are supplied for:

• Automotive gas spring assemblies
• Industrial gas spring systems
• Motion-control components requiring consistent pressure retention
