Hydraulics & Pneumatics

Discover hydraulic and pneumatic sealing excellence, where innovation meets the demands of modern fluid power.

Hydraulic seals, crafted from a range of materials such as polyurethane, rubber, or PTFE, play a pivotal role in machinery by blocking or separating fluid in reciprocating motion applications. They are the unsung heroes that convert fluid power into linear motion. Whether you require static seals for gasket-like functions or dynamic seals like rod and piston seals to prevent leakage and maintain pressure, we have you covered.

In the realm of pneumatics, a branch of engineering harnessing the power of gas or pressurized air, our products and expertise shine as well. Pneumatic systems, commonly driven by compressed air or inert gases, find application in various industries, from factories to dentistry and construction. We offer solutions powered by compressed air that are cost-effective, flexible, and safe alternatives to traditional electric or hydraulic systems.


Why Choose Hydraulic Seals?

Hydraulic seals play a crucial role in industries by stopping leaks, keeping pressure steady, and making machines last longer, all while being cost-effective and boosting safety.

Fluid Containment

Hydraulic seals are engineered to block or separate fluids in reciprocating motion applications. They create a barrier that prevents leaks and ensures the fluid remains contained within the hydraulic system. This containment is crucial for maintaining the efficiency and safety of machinery.

Conversion of Power

Hydraulic seals play a pivotal role in converting fluid power into linear motion. This conversion is at the heart of many industrial processes, enabling the controlled movement of components like cylinders and pistons. Without reliable seals, the fluid power would dissipate, rendering the machinery ineffective.

Maintenance of Pressure

Hydraulic systems often operate at high pressures. Hydraulic seals, including rod seals and piston seals, are designed to maintain these pressures within the system. Without effective sealing, pressure loss can occur, leading to reduced system performance and potential safety hazards.

Longevity and Reliability

Hydraulic seals are known for their durability and long operating life. They are designed to withstand the rigors of industrial applications, including exposure to extreme temperatures, high pressures, and continuous movement. Their resilience reduces maintenance requirements and enhances overall system reliability.

Cost-Effective Solution

By preventing fluid leaks and maintaining system efficiency, hydraulic seals contribute to cost savings in the long run. Reduced downtime, lower maintenance costs, and improved equipment lifespan all add up to a more cost-effective operation.


Hydraulic seals enhance safety by minimizing the risk of hydraulic fluid leaks, which can pose safety hazards in the workplace. By containing the fluid and preventing it from escaping, hydraulic seals help create a safer working environment for operators and maintenance personnel.

Environmental Protection

In addition to preventing fluid leakage, hydraulic seals also contribute to environmental protection. They help ensure that hydraulic fluid stays within the system, preventing contamination of the surrounding environment. This is especially critical in applications where fluid leaks could have adverse effects.


Hydraulic seals are available in various materials, such as polyurethane, rubber, and PTFE. This versatility allows for the selection of the most suitable material based on specific operating conditions, including fluid type, pressure, chemical compatibility, and temperature. This adaptability ensures optimal performance and longevity.

Why Choose Pneumatic Seals?

Pneumatic seals are your go-to solution for maintaining precise air pressure, ensuring reliability, and reducing maintenance hassles in pneumatic systems, all while keeping things simple and cost-effective for various industries

Efficient Air Containment

Pneumatic seals are designed to efficiently contain and control pressurized air or gases. They create airtight seals that prevent the escape of air from the system. This air containment is crucial for the proper functioning of pneumatic devices and actuators.

Precision Control

Pneumatic systems rely on precise control of air pressure to achieve various tasks. Pneumatic seals play a critical role in maintaining consistent pressure levels within the system, ensuring accurate and repeatable performance. This precision is essential in applications where control and reliability are paramount.

Flexibility and Versatility

Pneumatic seals are compatible with a wide range of gases, making them highly versatile for different applications. Whether your pneumatic system utilizes compressed air, inert gases, or other specialized gases, there are pneumatic seals designed to meet your specific needs.

Low Maintenance

Pneumatic seals are known for their low maintenance requirements. Unlike hydraulic systems that use hydraulic fluids, pneumatic systems use compressed air or gases, which are clean and do not require frequent replacement or maintenance. This results in reduced downtime and cost savings over time.


Pneumatic systems are inherently safer than hydraulic systems because they use compressible gases rather than incompressible liquids. In the event of a system failure, the potential for catastrophic accidents is significantly reduced. Pneumatic seals contribute to this safety by maintaining the integrity of the pneumatic system.

Cost-Effective Solution

Pneumatic systems are often more cost-effective than their hydraulic counterparts, and pneumatic seals play a role in this cost efficiency. The simplicity of pneumatic systems, along with the longevity and low maintenance requirements of pneumatic seals, translates to reduced operational costs.

Clean Operation

Pneumatic systems are clean and environmentally friendly because they do not involve the use of hydraulic fluids, which can pose contamination and disposal challenges. Pneumatic seals help maintain the cleanliness of the system, making them suitable for industries with strict cleanliness requirements.


Pneumatic systems can be easily integrated into various applications and industries. Pneumatic seals are available in a variety of sizes and materials, allowing for customization to meet specific operational conditions, pressure ranges, and environmental factors.

Common Types

Rod Seals

Rod seals, including U-cups and Polypaks™, are critical components in hydraulic and pneumatic systems. They are installed on the reciprocating rod or shaft of a cylinder to prevent fluid leakage from the system. U-cups, with their distinctive U-shaped profile, offer efficient sealing for various applications, while Polypaks™ provide excellent sealing performance with an O-ring expander. These seals ensure that hydraulic or pneumatic pressure is maintained within the cylinder, allowing for the controlled movement of the rod.


Wiper seals, also called scraper seals, are essential for maintaining the cleanliness of hydraulic and pneumatic systems. They are typically installed on the outer side of hydraulic or pneumatic cylinders to prevent contaminants like dust, dirt, and moisture from entering the system. Wipers help extend the lifespan of other sealing elements, such as rod seals and piston seals, by minimizing wear and preventing damage to the cylinder's internal components.

Piston Seals

Piston seals, as the name suggests, are installed on the piston head of hydraulic or pneumatic cylinders. Their primary function is to prevent fluid from passing across the piston and ensure that pressure is maintained within the cylinder. These seals play a crucial role in enabling the controlled movement of the piston, translating fluid power into mechanical work efficiently.

Wear Rings

Wear rings, also known as guide rings or guide bands, are used to reduce friction and minimize wear between moving components in hydraulic and pneumatic systems. They are typically installed on the inside of hydraulic cylinders to guide and support the piston or rod. Wear rings provide a smooth and stable surface for these components to move against, increasing system efficiency and longevity by reducing frictional losses and wear.

Buffer Seals

Buffer seals, sometimes called cushion seals or bumper rings, are used in pneumatic systems to protect primary sealing elements, such as piston seals, from pressure spikes and excessive wear. These seals are typically installed in the cylinder head to act as a cushion, absorbing sudden increases in pressure when the piston reaches the end of its stroke. Buffer seals help improve the durability and reliability of pneumatic systems.

Vee Packing

Vee packing, also known as chevron packing, consists of multiple rings or chevron-shaped seals stacked together. This sealing arrangement offers exceptional sealing capabilities in high-pressure applications. Vee packing is commonly used in both hydraulic and pneumatic systems, providing effective sealing for pistons and rods. Its versatility and ability to handle high-pressure conditions make it a reliable choice for demanding industrial applications.

Backup Rings

Backup rings, or anti-extrusion rings, support O-rings in hydraulic and pneumatic applications, preventing their extrusion or damage under high pressure. In hydraulics, they enhance O-ring performance and longevity, maintaining sealing integrity. Similarly, in pneumatics, backup rings provide reinforcement to O-rings, especially in higher pressure systems, ensuring reliable sealing solutions. These rings work in tandem with O-rings to contain fluids and maintain pressure while preventing leakage. Proper material and size selection are crucial for their effectiveness.


O-rings are versatile circular seals used in hydraulic and pneumatic systems to create airtight or fluid-tight connections between mating surfaces. In hydraulics, they prevent fluid leaks and maintain pressure, while in pneumatics, they ensure precise control by sealing joints and connectors. O-ring selection depends on compatibility with fluids, temperature, and system pressure.
