General Description Hydraulic Seals


Hydraulic seals can be made of a variety of materials, the type of material being determined by specific operating conditions or limits due to fluid type, pressure, liquid chemical compatibility or temperature.

The company owns 6 Economos SKF-Austria sealing machines and with their help we can produce hydraulic and pneumatic seals with diameters up to 600 mm.

SKF is the world leader in product supply, customer-oriented solutions and service in bearings and sealing field. The raw material used to produce hydraulic and pneumatic seals with our SKF sealing machines is of the highest quality, all tubes being ultrasonically tested to provide high-quality seals.

Raw material used to produce hydraulic and pneumatic seals are: Polyurethane Elastomers (PU), NBR Elastomers, elastomers as: FPM, EPOM, AEM, AFLAS and thermoplastic materials as POM, PA, PTFE, PTFE+Bz, PTFE + Carbon, PTFE + Graphite, PEEK.

Romania Hidro Service offers a wide range of standard and “customized” compounds that meet the increasingly complex market requirements.

A hydraulic seal is a relatively soft ring with the role of blocking or separating the liquid from the piston in motion applications.

There are several important factors to consider when choosing the right sealing solution:

  • Compression set
  • Hardness
  • Tensile strength
  • Final elongation
  • Resilience

Once these parameters are set, you are ready to continue checking the chemical compatibility, temperature limits, and material storage and handling. Material specifications help the user to identify the correct material.

We also export hydraulic and pneumatic seals in countries such as: France, Italy, Bulgaria, Republic of Moldova, Spain, Belgium, Switzerland, India.

We are at your disposal at our headquarters on 3 Primaverii Street, Targu Jiu, Gorj or by phone 0253 228 443 and 0728 253 209.
