Choosing the Best hydraulic seals manufacturers: 5 Things to consider

Choosing the Best hydraulic seals manufacturers: 5 Things to consider


3 Major Hydraulic Seals Manufacturers Sealing Types

Hydraulic systems depend on a fully efficient operation for the fluidity of liquids in a fast and very functional way. To ensure that everything is in order and working perfectly, it is necessary to keep up with the hydraulic seals manufacturers. It is only with a well-sealed system that efficiency can be measured.

Hydraulic seals manufacturers

The well-sealed cylinders primarily prevent the leakage of hydraulic system fluids. Moreover, it ensures the constant speed of the system’s actuators. In addition to the main sealing prevention factor, it must ensure that the system works well at high pressures. Similarly, the internal transversal forces are active.

Hydraulic seals manufacturers Sealing types

Hydraulic systems need to go through several types of seals. It is to be:

  • Functional
  • constant and

For this reason, there is a combination of factors that must be done. So, there is the possibility of a pressure increase in the piston half. And the cylinder can extend or retract effectively.

Hydraulic seals manufacturers should also focus on the scraper seal. It is mainly for cleaning purposes. It is responsible for removing:

  • dirt
  • impurities
  • foreign particles or
  • moisture from the actuator stem

Moreover, it should ensure that they do not enter the hydraulic system and contaminate the oil.

Hydraulic seals manufacturers Problems encountered in unsealed cylinders

Inadequate seals are the main villains of a hydraulic system around the cylinder. They can lead to a number of problems, among the most common and the most worrying. Improper installation can and should be avoided by hiring the service by a specialized professional.

Other very common problems are:

Oil contamination

usually caused by external issues that enter the system due to poor sealing;

Heat degradation

Mainly due to the high temperatures at which the seal is placed in contact and a bad installation.

Loss of system speed due to constant leaks

Have you learned how sealing a cylinder works and its importance for a hydraulic system to work perfectly? Now it’s time for Hydraulic seals manufacturers to be here to help you!

DSHseals is an expert company. Similarly, we are always updating and progressing with our products and services to better serve what you are looking for.


Check out some information about machined seals used in hydraulic cylinders. So, you can learn a little more about these products.

What are?

A hydraulic cylinder, in short, is an actuator. Subsequently, it aims to transform hydraulic energy into mechanical energy. And the seals machined for this equipment, it aims to seal the system. Furthermore, it keeps the fluids in the internal environment minimizing leakage. Hence it prevents the entry of impurities from the external environment.

The machined seals are manufactured to measure, through a set of actions. That use the high technology of the:

  • CNC lathe
  • specific software and
  • tools

It is to create a part with high performance for the customer.

Applications of Hydraulic seals manufacturers for hydraulic cylinders

Hydraulic cylinders and consequently their seals, can be found in different segments:

  • Food
  • Pharmaceutical
  • Forestry
  • Mining
  • Petrochemical
  • Steel
  • mechanical metal
  • pulp and
  • paper industry
  • in agriculture, in the road sector and much more.

Without Hydraulic seals manufacturers, it is impossible to meet the requirement of these industries.

To exemplify where we can find these parts in our day-to-day, we can mention machines such as:

  • cranes
  • tractors
  • backhoes and
  • hydraulic presses
Advantages in choosing machined seals for hydraulic cylinders

Hydraulic seals manufacturers and suppliers

Choosing machined seals for hydraulic cylinders within your system brings some advantages, such as:

  • Cost-effective when compared to traditional sealing models
  • Production time is around 1 working day
  • Tailored parts to meet your needs
  •  There is no need to change measurements of your equipment
  • Wide range of profiles available
  • Parts with greater durability and high performance
  • It dispenses with classic processes such as mold making, vulcanization and curing of the part.
  • More than 15 different compounds for different applications

Hydraulic seals manufacturers machined Seal Models for Hydraulic Cylinders

You will find several profiles of machined seals to be used in systems with hydraulic cylinders.

Each profile has a specific application. There are several options of:

  • Gaskets
  • o-rings
  • Scrapers
  • guide rings, and much more.

It is worth remembering that the models are made to measure. Hence, it means that there is no need to change the hydraulic cylinder of your system.

Materials for making parts

Hydraulic seals manufacturers can manufacture the seals machined for hydraulic cylinders. Each one is indicated for a specific purpose.

The most used raw materials are Nitrile Rubber, Teflon-PTFE, and Polyurethane. However, it is possible to manufacture machined seals from other materials, such as:

  • FPM – Viton;
  • FDA silicone
  • Polyacetal
  • Polyamide
  • UHMW
  • Special compounds and more

What to take into account when choosing the type of hydraulic seals?

Each profile and material have its particularities and characteristics. It makes them preferable for specific conditions.

Therefore, we have separated a list of items that must be analyzed. Moreover, it helps you choosing the best machined seal for the hydraulic cylinder of your system, check out:

  • the pressure range of the system to be sealed
  • the temperature range of the system to be sealed
  • Speed of movement of the hydraulic cylinder
  • dimension of the hydraulic cylinder to be sealed
  • which the application / function of the hydraulic cylinder
