Hydraulic Seal

The hydraulic seals are similar to gasket appearance. They function as sealed in the middle of hydraulic cylinder parts. Since there are fluid-prone components, the hydraulic seals help maintain no-leaking occurrences. Moreover, they are designed with the following advantages.

  • Specific design can work well in high or low-pressure operation
  • Cost-effective and easy to maintain
  • Highly versatile and sustainable
  • Wear and tear-resistant
  • Fewer chances of downtime
  • It prevents entering dirt from the system

How to Choose the Right Hydraulic Rubber Seals

Selecting suitable hydraulic seals for a specific application is necessary to achieve the best performance.  Here are some factors to include when choosing the right ones.

Shaft Speed 

The shaft speed comprises shaft finish, concentricity, housing bore, and more. They establish the maximum rotating capacity of a seal. 


Pressure level evaluation is needed. It determines whether the installed hydraulic seal capacity can accommodate specific pressures. 

Shaft Hardness

Rockwell hardness level of the shaft determines its lifespan and resistance. Therefore, this factor should regard.

Temperature Range

The temperature should be at most a seal can tolerate. It needs to have more resistance to the applied area.

Surface Finish

Its sealing performance improves with the proper surface treatment. The polished surface finish marks as most in demand.

Different Hydraulic Seal Types

There are numerous types of hydraulic seals. To identify them, consider the below with brief details.

  • V-ring is suitable for hydraulic cylinders with low moving speed and high working pressure.
  • U- ring is suitable for hydraulic cylinders with low working pressure or low moving speed.
  • Y- ring is suitable for hydraulic cylinders with high-speed variable pressure, large cylinder diameter, and large stroke.
  • YX- ring is especially suitable for hydraulic cylinders with high pressure, high speed, and rapid movement.

What Causes Hydraulic Seal Damages

Listed here are the typical causes that damage hydraulic seals. 

Hardening. The seal hardens when exposed to extreme temperatures. 

Scarring. Dents and cuts may compromise its operational efficiency.

Fractures. Breaking, cracks, and bents cause the seal to fracture. 

Improper Installation. Hydraulic seals may experience issues if improperly placed.

Chemical Erosion. A seal material will degrade if it cannot withstand chemical conditions.

Installation Guidelines 

Before starting the procedure, consider these tips to guarantee an optimal installation.

  • Checking Components

A close inspection is required to check for the installation-related components to see any indications of damage. Minimal scratches on the seal could lead to further damage.

  • Cleaning of Tools

Cleaning on tools for the seal’s installation improves effectiveness. Additionally, doing this preparation prevents leakage as it removes the excess elements. 

  • Seal Lubrication

The seal’s durability and abrasion resistance are increased by lubricant treatment. It has to be compatible with the seal’s material.

  • Heating 

Heating the seals improves their elasticity. There are more options to carry out this process, such as using hot lubricant. Do not heat the seal beyond its temperature limit, and do not overstretch the seal after heating.
