Hydraulic Seals – Dependable Performance

Hydraulic systems are sealed using a combination of specialized components. Together, these components inclusive of the seal have to withstand high pressures, extreme temperatures and transverse forces within the cylinder.

In hydraulic applications, each of the pneumatic seals plays a critical role in keeping the system running efficiently. Hydraulic rod seals prevent fluid from leaking outside the cylinder. Hydraulic piston seals prevent fluid from flowing across the cylinder head. Hydraulic wear rings guide the piston and rod within the cylinder, absorbing forces and preventing metal-to-metal contact. And, hydraulic wipers scrape moisture, dirt and other foreign particles from the piston rods as they retract into the cylinder.

Complete Line of Hydraulic Seals

 

Hydraulic Rod Seals

Rod seals are used in hydraulic cylinders for fluid sealing. GBSA offers a wide range of effective hydraulic rod seals including polyurethane o-rings. We will work with you to ensure our rod seal designs meet your application requirements.

Hydraulic Piston Seals

Piston seals are used to prevent pressurized fluid from leaking across the cylinder head while system pressure pushes the piston down the cylinder bore. GBSA engineers can assist you with both single-acting and double-acting piston seal designs.

Hydraulic Wear and Guide Rings

Hydraulic wear rings guide the piston, keeping it centered, which allows for even wear and pressure distribution on the seals. They also prevent metal-to-metal contact, optimizing the performance of the sealing system and increasing the seals’ lifespan. GBSA provides wear and guide rings in a variety of cut styles.

Hydraulic Wipers

Hydraulic wipers prevent contaminants, such as water, dust and debris, from entering the cylinder assembly and hydraulic system. Also known as scrapers or dust seals, hydraulic wipers are crucial to preventing damage to other system components. Contact GBSA today to discuss hydraulic wipers specific to your application.
