NOK Oil Seals

NOK delivers a wide range of products with high quality and outstanding functionality, including oil seals made with advanced sealing technology. In particular, it is widely used in cars to support a safe and comfortable life through highly functional and environmentally friendly NOK products.

Mechanical Seals

Mechanical Seals are surface finish seals that use a pair of surfaces perpendicular to a rotating shaft (shear surfaces) for sealing. The sealing surface, finished with high accuracy, allows the user to be maintenance free in the long run.

Automotive & Motorcycle Oil Seals

Used in automotive engines to prevent oil leakage at the ends of rotating shafts and the entry of dust particles from the outside. Oil Seals are made by attaching the synthetic rubber part that forms the seal lip to a metal ring. The embedded "spring" provides just the right amount of grip on the shaft, making it possible to seal moving parts.

Valve Stem Seals

Valve Stem Seals were developed for engines in a variety of vehicles, which often operate under the harsh conditions of extreme environments. Manufactured from high-performance materials designed to extend the life and reduce wear. They are supplied in various geometries to meet different assembly requirements. Different types of valve stem seals are also available to suit customer application requirements.

Hydraulic Packing Seals

Today's industrial equipment is facing new innovations, such as the development of outstanding mechatronic techniques and significantly advanced factory automation. In the field of operation and control of hydraulic and pneumatic equipment, in particular, the performance of NOK gaskets is developing rapidly.

NOK conducts its own research on rubber materials, resin materials and lip shapes affecting sealing performance, and since 1960. So it always offers material advancements to meet customer needs.
