#6 O-Ring Epr

The AEROQUIP #6 O-Ring EPR is a critical sealing component engineered for high-pressure hydraulic and pneumatic systems common in aerospace, industrial, and tactical equipment applications. This set of five replacement o-rings meets AS568 standards for 6 AN (AN6) fitting sizes, delivering reliable sealing performance across demanding operating conditions where leakage cannot be tolerated.

EPR (EPDM) elastomer construction provides excellent chemical and thermal resistance, making these o-rings suitable for both fuel and non-fuel applications in temperature ranges where standard Buna-N would degrade. The #6 AN size corresponds to a nominal 3/8-inch OD, fitting the standard AS568-A015 profile. AEROQUIP's manufacturing ensures tight tolerances and consistent cross-section, critical for maintaining system pressure integrity and preventing catastrophic fluid loss in high-pressure circuits. The set of five provides redundancy for repairs, maintenance cycles, or stock replenishment across multiple assemblies.

These o-rings are essential for anyone maintaining hydraulic brake systems, fuel delivery systems, or pneumatic equipment that relies on AN-standard fittings. Field technicians, armorer shops servicing aircraft or heavy equipment, and maintenance personnel in industrial settings depend on quality sealing components to avoid downtime and safety risks. Stocking verified AEROQUIP o-rings ensures you have certified replacements on hand when system maintenance or troubleshooting requires o-ring replacement.

AEROQUIP, a subsidiary of Parker Hannifin, is recognized across aerospace and industrial sectors for precision fluid power components. These o-rings meet or exceed industry standards and are traceable to verified manufacturing specifications, making them a reliable choice for critical system repairs.
