Round gaskets
Round seals are precision sealing elements used in hydraulic, pneumatic, and gas installations as well as in industrial machinery. They ensure the sealing of static and dynamic connections, resistance to pressure, temperature, and chemical agents. We offer a wide selection of sizes and materials (including NBR, EPDM, FKM, silicone) tailored to specific applications.
What is the difference between a round seal and an O-ring?
An O-ring is a round seal with a circular cross-section, manufactured according to dimensional standards. Round seals may have different cross-sections, diameters and materials, and their application is not limited exclusively to typical O-ring grooves.
How to properly select a round seal for an application?
The key parameters are: inner diameter, outer diameter, cross-section thickness, hardness and material compatibility with the medium. Selection is based on measuring the groove and verifying the dimensions in the manufacturer's tables.
From which materials are round seals manufactured and when should they be used?
NBR: oils, fuels, lubricants.
EPDM: water, steam, aqueous chemicals.
FKM: high temperatures, aggressive media.
Silicone: wide temperature range, food industry.
The material is selected according to the medium, temperature and pressure.
Are round seals suitable for operation under high pressure?
Yes, if they have the appropriate hardness and operate in a properly designed groove. In high-pressure applications, back-up rings are often used.
What are the most common applications of round seals?
Hydraulics and pneumatics, industrial fittings, pumps, valves, water and heating installations, automotive industry, food processing equipment. They ensure sealing of static and dynamic connections.
How should round seals be stored to maintain their parameters?
In a dry, cool place, without exposure to UV, ozone and high temperature. Without mechanical stresses and contact with incompatible chemicals.
Can a round seal be replaced with another type of sealing?
It is possible, but it requires an analysis of the groove design and operating conditions. Replacement without verification may reduce sealing performance or shorten the service life of the system.
