O-Ring NBR 228x5 mm 70 Shore A

Applications in Hydraulic and Industrial Systems

The O-Ring NBR 228x5 mm 70 Shore A is a precision rubber gasket designed for reliable static sealing in demanding industrial environments. The dimension 228x5 means 228 mm inner diameter and 5 mm cross-section, ensuring accurate fit in properly machined grooves.

This industrial sealing ring is widely used in hydraulic systems, pneumatic installations, flanged connections, pipe assemblies, and heavy machinery components. When correctly compressed, the O-Ring provides a tight static seal, preventing leakage of oil, grease, air, and other operating media.

It is a trusted solution for maintenance departments, production facilities, and industrial procurement teams requiring consistent sealing performance.

NBR 70 Shore A - High Durability and Oil Resistance

Manufactured from nitrile butadiene rubber (NBR) with hardness 70 Shore A, this O-Ring offers high durability and excellent resistance to oils and grease. NBR is one of the most commonly used elastomers in hydraulic and automotive sealing due to its balanced mechanical strength and chemical resistance.

The typical operating temperature range is approximately -30°C to +100°C, making it suitable for a wide range of industrial applications. The material ensures stable performance under pressure and long service life in technical sealing components.

Reliable Static Sealing Performance

The O-Ring 228x5 mm is primarily intended for static sealing applications, where there is no relative movement between connected parts. Proper installation guarantees uniform compression and consistent sealing effectiveness.

It is suitable for hydraulic and pneumatic applications, industrial machinery, and technical sealing assemblies where reliability and high resistance are essential.
