Designed for reliability in high-stress industrial environments, 3-Inch ARKPEEK® PEEK Seals deliver unmatched performance in extreme conditions. These seals combine advanced material science with precision engineering to outperform metals, elastomers, and traditional polymers in critical applications.

Material Grades & Advantages

ARKPEEK-1000® (Virgin PEEK):

Chemical Purity: FDA-compliant for food/pharma and ultrapure fluid systems.

Chemical Resistance: Resists acids, solvents, and hydrocarbons without leaching.

ARKPEEK-GF30® (30% Glass Fiber):

Dimensional Stability: Minimal thermal expansion under cyclic loads.

Applications: Steam valves, heat exchangers.

ARKPEEK-CF30® (30% Carbon Fiber):

High Strength: Handles 500+ bar pressure; static-dissipative for explosive environments.

Applications: Hydraulic pumps, compressors.

ARKPEEK-MOD® (PTFE/Graphite/Carbon Blend):

PTFE: Reduces friction by 60% vs. standard PEEK.

Graphite: Self-lubricating for dry-running conditions.

Carbon Fiber: Prevents wear in abrasive environments.

Triple Reinforcement:

Applications: Slurry pumps, chemical reactors.
