O-Ring 5 x 1.6 mm NBR 90 ShA

Applications

This metric O-Ring 5 x 1.6 mm, manufactured from nitrile-butadiene rubber (NBR) with a 90 ShA hardness rating, is engineered for demanding industrial sealing tasks. It serves as a durable rubber gasket or sealing ring in compact glands, fittings and components across hydraulic and pneumatic systems as well as other industrial machinery. Whether you’re implementing a static seal in a valve housing or a light-motion seal in a small actuator, this O-ring offers excellent performance. Supplied in a pack of 100, it is optimized for maintenance, service kits and procurement batches in engineering operations. The high-hardness NBR compound provides strong chemical resistance to oil, grease and common industrial fluids, making it an ideal technical sealing component in demanding production environments.

Advantages

• High durability and high hardness (90 ShA): The firm NBR compound resists extrusion and wear, ensuring consistent sealing performance under pressure in both static and low-motion applications.

• Pack of 100—efficient supply for B2B: The bulk pack format supports operations teams, MRO professionals and system integrators: one SKU, one reorder point, minimal downtime.

• Versatile industrial sealing for hydraulics & pneumatics: Designed for use as an O-Ring in hydraulic cylinders, pneumatic valves and precision compact components, this seal supports industrial installations with increased uptime.

• Compact metric format (5 x 1.6 mm): Suitable for small-bore glands, miniaturised components and systems where space is at a premium—while still offering robust sealing capacity.

FAQ

Q1: Why choose 90 ShA hardness for this O-Ring?
A: A 90 ShA rating indicates a relatively firm elastomer, providing better resistance to deformation and extrusion in compact gland designs. It’s suited for industrial sealing in systems where the seal must endure pressure and maintain shape.

Q2: Is NBR suitable for hydraulic oil and grease environments?
A: Yes. Nitrile (NBR) is widely used for rubber gaskets in hydraulic and pneumatic systems due to its strong compatibility with mineral oils, greases and many industrial fluids. Always verify the specific fluid and temperature conditions in your system.

Q3: Can I use this O-ring in a dynamic application (moving parts)?
A: This product is primarily intended for static sealing or light motion. For heavy dynamic use (high speed, strong reciprocation), ensure gland design is correct and consider special compounds if needed.

Q4: How do I verify the correct fit for ID 5 mm and CS 1.6 mm?
A: Confirm the gland or groove inner diameter is close to 5 mm and the cross-section clearance allows for 1.6 mm. Proper installation ensures correct compression and avoids leakage or premature failure.

Q5: What advantages does the pack of 100 pieces offer?
A: The bulk pack format streamlines procurement, stocking and maintenance planning. It reduces administrative overhead and supports fast replacements during servicing or production downtime mitigation.
