2. O-Rings O-rings are circular seals that fit into a groove and are used to prevent dust and liquid from entering or escaping a mechanical assembly. They are versatile and are often made of rubber or silicone, allowing for flexibility in design.

4. Inspect the Components Once disassembled, inspect the cylinder and other components for signs of wear or damage that may need addressing beyond just seal replacement.

Some applications require specialized or customized hydraulic seal kits. These kits may be designed for unique machinery or extreme operating conditions. Customization often means higher costs due to the specific engineering, research, and development involved. If your application has unique requirements, it's essential to factor in this cost when budgeting for hydraulic seals.

3. Backup Rings These are used alongside the seals to support them and prevent extrusion, especially in high-pressure situations.

2. U-Cup Seals These are typically made from elastomeric materials and are designed with a U-shaped cross-section. U-cup seals are highly effective in high pressure applications and provide excellent sealing performance by distributing pressure evenly across the sealing surface.
