What are the consequences of improper installation of hydraulic seals?

Ensuring the proper installation of seals within your hydraulic system is crucial. When seals are not installed correctly, it can lead to several issues, including hydraulic fluid leaks, diminished power output, and rod drift.

Hydraulic cylinder seals are typically crafted from delicate materials that are susceptible to harm. Therefore, when handling and installing new seals, it’s imperative to exercise caution and maintain a sterile environment.

Seals that have incurred chips, tears, dirt, or cracks should not be utilized. Using damaged seals, often a result of improper installation, is a prevalent cause of hydraulic fluid leakage.

What are the effects of hydraulic leaks?

Hydraulic leaks can be divided into two types: external and internal. External leaks occur when hydraulic fluid escapes the system, while internal leaks arise when fluid seeps between different components.

A common cause of internal leaks is a compromised or worn piston seal, responsible for preventing fluid from leaking across the piston. While internal leaks don’t result in fluid loss, they do reduce power output and may cause rod drift, affecting the machine’s ability to maintain hydraulic attachments in a fixed position.

On the other hand, external leaks often stem from a damaged or deteriorated rod seal. When the rod seal loses its integrity due to debris or heat, hydraulic fluid begins to escape the system.

How to properly install new hydraulic cylinder seals?

When seals deteriorate or sustain damage, they should be replaced promptly. Depending on the complexity of your machinery, you may opt to replace the seals yourself, but if uncertain, seeking assistance from a trained specialist is advisable.

Selecting the appropriate type of hydraulic cylinder seal is crucial to prevent leaks and contamination. It’s essential to adhere to the seal size, material, and design specified in the machine’s service manual.

Attaching new seals is a relatively straightforward process if you possess the necessary tools and experience. Begin by removing the old seals, ensuring not to damage the cylinder’s components. Then, carefully insert the new seals, paying attention to their orientation and ensuring they fit snugly without damage.

How often should hydraulic cylinder seals be replaced?

Ideally, Car Lift Repair Orlando hydraulic cylinder seals should be replaced every three years. However, with proper maintenance and clean fluid, high-quality seals can last even longer. Premature seal damage often indicates underlying issues within the hydraulic system, such as contaminated fluid or damaged components, necessitating prompt attention.

In industrial settings, hydraulic seals play a critical role in preventing fluid or gas from passing between various components within a cylinder, ensuring efficient and safe system operation. However, not all seals are created equal, and different applications may demand specific seal types. In this blog post, we delve into the key considerations for selecting the most suitable seal material to optimize performance for your specific application.

Choosing the Appropriate Seal:

Material and Design Considerations:

When choosing a hydraulic seal, careful consideration of its material and design is essential to ensure effectiveness, safety, and reliability.

Temperature Compatibility:

Temperature stands as one of the foremost factors in Car Lift Repair Orlando seal selection. The seal’s temperature range must align with the operational environment to prevent premature failure. The material composition dictates the temperature range a seal can withstand, with materials like rubber excelling at low temperatures and metals being more adept at higher temperatures. Moreover, the seal must endure temperature fluctuations typical of its environment, such as those found outdoors versus in a climate-controlled setting.

Handling High Pressure:

Not all Car Lift Repair Orlando seals are equipped to handle high-pressure environments. For applications requiring high-pressure sealing, selecting a seal material resistant to deformation or breakage is imperative. The seal’s design should facilitate a tight seal without excessive friction, and proper lubrication is essential to prevent wear and tear. Common high-pressure seal types include O-rings, V-rings, and piston seals, each available in materials like rubber, nitrile, and fluorocarbon.

Fluid Compatibility:

Ensuring compatibility between the Car Lift Repair Orlando seal and hydraulic fluid is crucial to prevent premature degradation and leakage. Factors such as the fluid’s chemical composition, operating temperature and pressure, and the seal material must be evaluated. Elastomers typically offer broad fluid compatibility, while plastics and metals may have more limited compatibility. Choosing a seal material compatible with the specific fluid used in the hydraulic system is vital for long-term performance.

Various Seal Materials:

Nitrile (NBR)

Characteristics: Car Lift Repair Orlando Nitrile seals exhibit good resistance to elongation at break, abrasion, and compression set. However, their flexibility diminishes in lower temperature ranges. Seals made from nitrile are vulnerable to ozone and require careful storage in most environments.

Temperature Range: Nitrile can endure temperatures ranging from -30°C to +100°C.

Fluid Compatibility: The most common nitrile copolymer blend, known as Buna-N, demonstrates excellent resistance to petroleum-based hydraulic oils and works effectively with fuels like diesel or gasoline.


Characteristics: Car Lift Repair Orlando PTFE boasts chemical inertness, high heat resistance, low temperature flexibility, low running friction, and non-adhesive properties. Due to PTFE’s lack of resilience, an energizer is typically used to achieve the desired fit. To maintain toughness and flexibility, most PTFE seals incorporate short glass fibers, bronze flashes, carbon graphite, or a blend of these fillers.

Temperature Range: PTFE can withstand temperatures exceeding 300°C, though this may be reduced by the filler or energizer used.

Ethylene-Propylene (EPDM)

Characteristics: Ethylene-Propylene (EPDM) offers good heat resistance, low compression set, and flexibility at low temperatures.

Temperature Range: Ethylene-Propylene functions within temperature ranges from -45°C to +150°C.

Car Lift Repair Orlando Fluid Compatibility: Ethylene-Propylene is suitable for sealing phosphate ester hydraulic fluids such as Skydrol but is not recommended for petroleum-based fluids. It performs effectively with steam, acetone, and dilute acids and bases. Specially formulated Ethylene-Propylene can be adapted for use in automobile brake systems.

Polyurethane (AU)

Characteristics: Polyurethane demonstrates high resistance to oil swell, ozone, oxidation, abrasion, and exceptional cut resistance. Urethanes are highly resilient, with excellent tensile strength and elongation properties. Formulated from copolymers of ether or ester-based urethanes, this material finds wide application in seals, wipers, backup rings, cushions, bumpers, and various other uses.
