Piston Seals

What are Piston Seals?

Piston Seals are essential components used to create a seal between the piston and the cylinder bore, preventing the leakage of hydraulic fluid or air. This internal seal allows pressure to be maintained on one side of the piston, generating the necessary force to move it back and forth. Piston seals are made from materials such as PU, HPU, BFT, and NBR.

How Does a Piston Seal Work?

A piston Seal functions by containing pressure on one side of the piston without any leakage. This enables maximum mechanical effort to be applied in moving the piston along the bore of the cylinder. Piston seals can operate in hydraulic or pneumatic systems, with designs tailored to suit each specific application.

Piston Seals are designed to prevent leakage past the piston, thereby maximizing the efficiency of the system. Pressure can be applied in one direction only (single-acting) or from both directions (double-acting), allowing the piston to drive the ram both in and out.

Types of Piston Seals

Hydraulic Single Acting Piston Seal (K 01)

The K 01 Hydraulic Single-Acting Piston Seal is a specialized component designed for hydraulic systems, particularly in applications where a piston needs to move in one direction only

Hydraulic Single Acting Seal (K 07)

Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing and are designed to ensure that pressurized fluid does not leak across the cylinder head as the system pressure pushes the piston down the cylinder bore

Hydraulic Double Acting Seal (K 08)

Double Acting Seals are widely preferred in hydraulic cylinders due to their versatile design. These seals offer the advantage of being pressurized from both directions, accommodating fluid or air, enabling the rod to move back and forth

Hydraulic Double Acting Piston Seal (K 10- 12)

The Hydraulic Double Acting Piston Seal (K 10-12) is a specialized component designed for precise control and efficient operation in hydraulic systems. The K 10-12 Hydraulic Double Acting Piston Seal is specifically engineered to provide reliable

Hydraulic Double Acting Piston Seal (K 17)

It comes with its high-quality bronze-filled PTFE ring. The durable design of the K 17 double-acting compact piston seal includes an elastomer energizer, a PTFE ring, and two thermoplastic backup rings

Hydraulic Double Acting Piston Seal (K 20)

The Hydraulic Double Acting Piston Seal is a critical component in hydraulic systems where precise control of fluid movement is essential. Unlike single-acting seals, double-acting piston seals can manage pressure from both sides of the piston

Hydraulic Double Acting Piston Seal (K 23)

The K 23 seal is designed to provide effective sealing in hydraulic cylinders that experience pressure from both directions. This seal is built to withstand high-pressure levels commonly found in hydraulic systems
