Cup Seals

Cup Seals are versatile sealing elements designed for use in hydraulic and pneumatic cylinders. These seals feature a cup-shaped design that allows them to create a tight seal against the cylinder bore, preventing fluid or air leakage. Cup Seals are commonly used in single-acting and double-acting cylinders where reliable sealing is essential for maintaining system pressure and efficiency. They are available in various materials and sizes to suit a wide range of applications.

Available Variations:

Standard Cup Seals: Ideal for general-purpose sealing in hydraulic and pneumatic systems.

Double-Lip Cup Seals: Provides additional sealing capability and is suitable for more demanding applications.

Custom Profiles: Available in custom shapes and sizes to meet specific requirements.
