28-Inch ARKPEEK® PEEK Seals: Big Size, Big Performance
When standard seals fail under the demands of large-scale industrial systems, 28-Inch ARKPEEK® PEEK Seals deliver unmatched durability. Designed for big-size applications, these heavy-duty seals combine advanced material science with precision engineering to outlast metals, elastomers, and traditional polymers.

Material Grades & Unique Advantages

ARKPEEK-1000® (Virgin PEEK):

Ultimate Purity: Ideal for food/pharma and chemical systems requiring FDA compliance.

Chemical Resistance: Impervious to acids, solvents, and hydrocarbons.

ARKPEEK-GF30® (30% Glass Fiber):

Thermal Stability: Minimal expansion at high temps (up to 260°C).

Applications: High-pressure steam valves, geothermal plant flanges.

ARKPEEK-CF30® (30% Carbon Fiber):

Strength & Conductivity: Handles 500+ bar pressure; dissipates static in explosive environments.

Applications: Offshore blowout preventers (BOPs), hydraulic fracturing systems.

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 slurries.

Triple Reinforcement:

Applications: Mining slurry pumps, subsea pipeline seals.
