Hydraulic Seals: page 14
Hydraulic seals are one of the most important components in any hydraulic system, as they ensure the cylinders remain sealed to prevent fluid leaks and maintain pressure, enabling the system to function correctly. Poor-quality seals would lead to inefficiency accompanied by high maintenance costs. Visit the Hydseal Store for fast delivery throughout Romania of a full range of hydraulic seals available from stock – piston seals, rod seals, sleeves, scrapers, guide rings and static seals. These ensure the sealing of hydraulic cylinders, minimising potential fluid leaks and maintaining the pressure required for the correct operation of the equipment.
Poor-quality seals lead to a rapid loss of cylinder efficiency and very high maintenance costs. At the Hydraulic Seals Shop, you will find a comprehensive range of hydraulic seals for pistons, rods, sleeves, scrapers, guide rings and static seals, available from stock with fast delivery throughout Romania.
Categories of hydraulic seals
Our catalogue contains all the types of seals required to fully seal a hydraulic cylinder:
- Hydraulic seals – for sealing the piston and rod in hydraulic cylinders.
- Scrapers – to protect the rod against dust, dirt and abrasive particles.
- Rod seals – dynamic sealing for the hydraulic cylinder rod.
- Guide rings – to maintain alignment between the piston and the rod and reduce wear.
- Piston seals – seals for the hydraulic cylinder piston, preventing fluid leakage between the cylinder chambers.
- Guide band – a continuous guide band used to reduce friction and wear in hydraulic cylinders.
- Vee Packing – V-shaped seals used in sets, providing an adjustable seal for high pressures.
- Static seals – for sealing fixed joints, with no relative movement between the sealing surfaces.
Areas of application
These are used in hydraulic cylinders for all industrial and mobile hydraulic systems, including: construction machinery, such as excavators, bulldozers, cranes, compactors and many others; agricultural machinery, including tractors, combine harvesters and hydraulic balers; presses, injection moulding machines and assembly lines in the manufacturing industry; forestry and lifting equipment; industrial and mobile hydraulic systems in the maritime and energy sectors.
Criteria for selecting hydraulic seals:
Choosing the right hydraulic seal is essential to ensure a long service life for the system as a whole. The main parameters to be taken into account are working pressure, fluid temperature, type of hydraulic oil and the speed of the piston or rod.
Pressure, temperature, working fluid, dimensions and material
High pressures will require polyurethane seals with increased extrusion resistance. The choice of material depends on the operating temperature: NBR is well suited to moderate temperatures; FKM is for high temperatures or aggressive fluids. The seal dimensions (inner and outer diameter, width) must match the cylinder’s specifications. However, the most important criterion is the chemical compatibility between the seal material and the hydraulic fluid.

What are hydraulic seals and where are they used?
Hydraulic seals are dynamic and flexible components used to seal hydraulic cylinders, preventing any fluid leakage and maintaining the cylinder’s working pressure. They are mainly used in construction machinery, agricultural machinery, static industrial hydraulic systems and mobile hydraulic systems.
What parameters should I consider when selecting hydraulic seals for my application?
You should select the seal based on the cylinder diameter, working pressure, fluid temperature and the material’s compatibility with hydraulic oil. Our team will provide you with free technical assistance in choosing the right solution.
When should hydraulic seals be replaced?
Hydraulic seals should be replaced when oil leaks start to occur or when the cylinder loses power and becomes harder to operate. They should also be replaced as a preventative measure if they are cracked, hardened or worn, even if no oil is leaking yet.
