4-Inch ARKPEEK® PEEK Seals: Robust Performance for Medium-Scale Industrial Challenges
Designed for reliability in mid-sized systems, 4-Inch ARKPEEK® PEEK Seals deliver unmatched durability in high-stress environments. Unlike smaller seals, these medium-bore components are tailored for applications requiring a balance of precision and robustness, such as industrial valves, chemical dosing pumps, and water treatment equipment.

Material Grades & Industry-Specific Benefits

ARKPEEK-1000® (Virgin PEEK):

Chemical Purity: FDA-compliant for food/pharma and ultrapure fluid systems. Resists acids, solvents, and hydrocarbons.

Applications: Chemical dosing pumps, pharmaceutical mixers.

ARKPEEK-GF30® (30% Glass Fiber):

Thermal Stability: Minimal expansion under cyclic thermal loads.

Applications: Steam control valves, heat exchangers.

ARKPEEK-CF30® (30% Carbon Fiber):

High Load Capacity: Withstands 500+ bar pressure in hydraulic systems.

Static Dissipation: Safe for explosive environments (ATEX/IECEx).

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

Triple Reinforcement: Ultra-low friction (µ=0.12) and abrasion resistance for gritty media.

Applications: Slurry pumps, mining equipment.

Why 4-Inch ARKPEEK® Seals?

Optimized for Medium-Bore Systems: Ideal for valves, pumps, and flanges in chemical processing, water treatment, and oil/gas.

Pressure & Temperature Mastery: Operates at -70°C to 260°C and 500 bar (MOD/CF30 grades).

Customization: Tailored cross-sections (quad-rings, lip seals) and backup ring integration.

Industry Applications

Water Treatment: Corrosion-resistant seals for chlorination systems and pH adjustment valves.

Chemical Processing: MOD-grade seals for abrasive slurry pumps.

Oil & Gas: CF30 seals for mid-pressure hydraulic fracturing equipment.

Food & Pharma: 1000-grade seals for sterile fluid transfer systems.

Technical Edge

Tolerance Precision: ±0.05mm for leak-free sealing.

Cycle Life: 500,000+ cycles (MOD/CF30 grades).

Certifications: UL94 V-0, FDA, RoHS, ISO 9001.

Solve Mid-Scale Challenges

Eliminate Downtime: 3x lifespan vs. PTFE seals in abrasive environments.

Reduce Costs: Fewer replacements and maintenance interruptions.

Fast Turnaround: Prototyping in 5 days; bulk orders in 2 weeks.
