Stone Crusher Piston Seal

ICOMAX Stone Crusher Piston Seals are specially engineered to deliver reliable, high-pressure sealing performance in the hydraulic cylinders of jaw crushers, cone crushers, impact crushers and VSI crushers. Designed to withstand heavy shock loads, continuous vibration and harsh operating conditions, our piston seals ensure maximum uptime and extended cylinder life in the toughest crushing and mining environments.

Types of Piston Seals We Offer

Single Acting Piston Seals
Provide sealing in one direction, ideal for hydraulic cylinders operating under single-direction pressure loads common in crusher rams and clamping cylinders.

Double Acting Piston Seals
Seal in both directions, suitable for hydraulic cylinders that require sealing performance on both the extend and retract strokes.

U-Cup Piston Seals
Flexible lip design providing excellent sealing at low and high pressure, commonly used in crusher hydraulic systems for consistent performance.

Compact Piston Seals
Combine sealing and wear-ring function in a single compact profile — ideal for space-constrained crusher cylinder designs.

Step Seal / Glyd Ring Piston Seals
Two-piece piston seal design offering low friction and excellent sealing under high pressure and dynamic loads.

Custom Piston Seals
Manufactured as per drawing or sample to match OEM or reverse-engineered crusher cylinder specifications.

Single Acting Piston Seals

At Icomax Techno Polymers, we manufacture and supply premium-quality Single Acting Piston Seals designed to provide efficient sealing performance in hydraulic cylinders where pressure is applied from only one side

Double Acting Piston Seals

Icomax Techno Polymers offers high-performance Double Acting Piston Seals designed to provide reliable sealing in hydraulic cylinders where pressure is applied alternately from both sides of the piston. Manufactured using premium-quality materials

U-Cup Piston Seals

Icomax Techno Polymers manufactures and supplies premium-quality U-Cup Piston Seals designed to deliver superior sealing performance in hydraulic cylinders. Featuring a U-shaped lip design, these seals provide excellent sealing efficiency under pressure while maintaining low friction .

Compact Piston Seals

Icomax Techno Polymers offers premium-quality Compact Piston Seals designed for hydraulic cylinders where installation space is limited without compromising sealing performance. These multi-component seals provide excellent leakage control, low friction, and superior wear

Step Seal / Glyd Ring Piston Seals

Icomax Techno Polymers manufactures and supplies premium-quality Step Seal (Glyd Ring) Piston Seals engineered for high-performance hydraulic applications. These seals consist of a precision-machined PTFE sealing ring combined with an elastomer O-ring that provides the necessary sealing force

Custom Piston Seals

Icomax Techno Polymers specializes in manufacturing Custom Piston Seals designed to meet the unique requirements of hydraulic systems across various industries. Whether you need a non-standard size, special material, or application-specific sealing solution

Backup Rings

Backup rings (anti-extrusion rings) are rigid, washer-like devices installed in the same groove as an O-ring to prevent it from extruding under high pressure. These support rings are typically
made from PTFE.

Compact Seals

Compact seals are specialized hydraulic and pneumatic sealing components engineered for applications where space is limited but high-pressure and low-friction sealing is required
