Oil Seals
Oil seals are radial shaft seals designed for sealing rotating shafts. Their primary function is to retain oil and lubricants within the system while preventing the ingress of dust, moisture and other contaminants.
They are widely used in electric motors, gearboxes, pumps, transmissions, industrial machinery and many other drive systems. They are available in various sizes, materials and designs to suit different temperatures, rotational speeds and operating media.
O-RINGS
O-rings are one of the most widely used sealing solutions in industry thanks to their simple design, high reliability and long service life. They are manufactured from a variety of elastomers designed to meet different operating conditions.
They are used in hydraulic and pneumatic systems, valves, pumps, cylinders and many other industrial applications where reliable sealing of liquids and gases is required.
Gland Packing
Gland packing is used to provide reliable sealing of rotating and static components in industrial equipment. It is most commonly installed in pumps, valves, mixers and other systems where leakage of liquids, gases or steam must be prevented.
It is manufactured from a variety of materials such as graphite, PTFE, aramid and synthetic fibres to suit different temperatures, pressures, operating speeds and media. Properly selected gland packing ensures long service life, reduced friction and minimal maintenance requirements.
Gasket Sheets
Gasket sheets are used to manufacture flat gaskets that provide reliable sealing of joints in pipelines, valves, heat exchangers, pumps and other industrial equipment. They are available in various materials to meet different operating conditions.
Astra Prom offers gasket sheets resistant to high temperatures, pressure, oils, fuels, water, steam and a wide range of chemical media. They are suitable for industrial applications, the energy sector, food processing and many other industries.
Engineering Rubber
Engineering rubber is used for manufacturing seals, pads, protective components and other industrial parts that must withstand mechanical loads, wear, oils, fuels, water, chemicals and a wide range of temperatures.
Astra Prom offers rubber sheets and engineering rubber materials in various hardness levels, thicknesses and compounds. The selection of the appropriate rubber type depends on the operating medium, temperature, pressure and application requirements.
Industrial Felt
Industrial felt is used for sealing, filtration, lubrication, surface protection and vibration damping in a wide range of industrial systems. Thanks to its structure, it can retain oil and lubricants while protecting components from dust and mechanical damage.
It is available in various thicknesses, densities and hardness levels depending on the application requirements. It can be cut and shaped to the required dimensions for installation in machinery, bearing housings, guideways and other technical assemblies.
