Piston Seals

Piston seals are used in hydraulic and pneumatic cylinders to prevent fluid from bypassing the piston, ensuring efficient pressure transfer and smooth motion. Designed for dynamic sealing, they provide high pressure resistance, low friction, and long service life in demanding applications.

Key Features:

  • Effective Shaft Bore Closure
  • Durable, Press-Fit Design
  • Resistant to Environmental Exposure

Rod Seals

Rod seals are critical components in hydraulic and pneumatic cylinders, designed to prevent fluid leakage along the piston rod as it moves in and out of the cylinder. Positioned at the cylinder head, they maintain internal pressure while keeping contaminants out. Made from high-performance materials like polyurethane, PTFE, or nitrile rubber, rod seals offer excellent wear resistance, low friction, and reliable performance in high-pressure, dynamic applications.

Key Features:

  • Custom design tailored to your outdoor space
  • Durable and aesthetically pleasing materials
  • Seamless integration with your home’s architecture

Wiper Seals

Wiper seals, also known as scrapers, are used in hydraulic and pneumatic cylinders to prevent dirt, dust, and moisture from entering the system as the rod retracts. Installed at the cylinder opening, they protect internal components from contamination, reducing wear and extending system life.

Key Features:

  • Integrated Multi-Lip Design
  • Pre-Assembled Cartridge Construction
  • Durability in Extreme Conditions

Buffer Seals

Buffer seals are installed in hydraulic cylinders ahead of the primary rod seal to absorb pressure spikes and reduce stress on the sealing system. They help manage residual pressure and fluid bypass from the piston, enhancing the performance and lifespan of downstream seals.

Key Features:

  • Custom design tailored to your outdoor space
  • Durable and aesthetically pleasing materials
  • Seamless integration with your home’s architecture

Wear Rings

Wear rings guide the piston and rod within hydraulic cylinders, preventing metal-to-metal contact and maintaining proper alignment. Made from low-friction, high-strength materials, they absorb side loads and ensure smooth operation in high-speed or heavy-duty applications.

Key Features:

  • Integrated Multi-Lip Design
  • Pre-Assembled Cartridge Construction
  • Durability in Extreme Conditions
