Reliable Sealing Performance

Main description

O-Ring 400x6 NBR 70 ShA is a high-quality industrial rubber seal designed for professional applications where reliability, durability, and precise sealing are essential. Manufactured from NBR (nitrile butadiene rubber) with a hardness of 70 Shore A, this O-Ring offers an optimal balance between elasticity and mechanical strength, ensuring consistent sealing performance under demanding operating conditions.

With an inner diameter of 400 mm and a cross-section of 6 mm, this sealing ring is particularly suitable for large-diameter assemblies used in industrial machinery, hydraulic systems, and pneumatic equipment. It is commonly applied as a static seal, but can also be used in low-speed dynamic applications when proper installation conditions are met.

The NBR compound provides excellent resistance to mineral oils, greases, fuels, and common hydraulic fluids, making this O-Ring a reliable choice for long-term industrial sealing. Its high resistance to abrasion, compression set, and aging significantly reduces maintenance intervals and minimizes the risk of leakage in critical systems.

O-Ring 400x6 NBR 70 ShA is widely used in pumps, valves, flanges, housings, tanks, and machine assemblies where secure sealing is required. Precise dimensional accuracy ensures uniform compression in the sealing groove, resulting in stable performance even under fluctuating pressure and temperature conditions. This makes the product especially suitable for industrial sealing components, maintenance departments, OEMs, and technical wholesalers operating in B2B environments.

Designed for efficiency and reliability, this rubber gasket supports smooth operation of hydraulic and pneumatic systems while meeting the expectations of professional buyers who require repeatable quality and dependable availability.
