Complete Range of Industrial Skeleton Oil Seals Durable NBR/FKM/EPDM/ACM Materials for Demanding Applications

In modern industry, high-performance sealing components are critical to ensure equipment efficiency, safety, and reliability. For systems operating under dynamic loads, extreme temperatures, or harsh chemical environments, a dependable oil seal is not optional—it is essential. That’s why we offer a complete series of industrial skeleton oil seals made from NBR, FKM, EPDM, and ACM materials, designed to meet the diverse needs of global industries.

NQKSF skeleton oil seals are reinforced with a metal framework (also known as a skeleton or cage) that provides structural rigidity and precise fitment. This metal reinforcement, combined with premium-grade rubber materials, ensures long-lasting sealing performance even under severe mechanical stress or pressure fluctuations. These seals are widely used in automotive systems, hydraulic cylinders, gearboxes, motors, pumps, and heavy-duty industrial machinery.

Available Material Options

NBR (Nitrile Butadiene Rubber):

Ideal for general-purpose oil resistance

Temperature range: -40°C to +125°C

Affordable and reliable for standard hydraulic and pneumatic systems

FKM (Fluorocarbon Rubber):

Outstanding heat and chemical resistance

Temperature range: -20°C to +250°C

Perfect for high-temperature engines, fuel systems, and aggressive fluids

EPDM (Ethylene Propylene Diene Monomer):
