O-Ring 122 x 3,55 mm NBR 80 ShA

Applications

The precision metric O-Ring 122 x 3,55 mm, manufactured from nitrile-butadiene rubber (NBR) with hardness 80 ShA, is engineered for demanding B2B applications in the industrial sector. Serving as a reliable rubber gasket, sealing ring or industrial sealing component, this product excels in static seals and light dynamic duties across hydraulic, pneumatic and fluid power systems. It is suitable for valves, actuators, pressure housings and system modules where durable sealing solutions are required. The size aligns with metric gland standards and customised assemblies, giving engineers and procurement professionals a dependable technical sealing component for robust installations.

The NBR 80 ShA compound offers an effective blend of elasticity and structural strength—making this O-ring ideal for applications where you need resilience under pressure, reliable performance in oil-based media and extended service life. With a diameter of 122 mm and cross-section of 3.55 mm, it supports large-bore seals while maintaining compact design benefits—perfect for operations requiring uszczelnienia do hydrauliki i pneumatyki that meet metric sizing.

Advantages

• Balanced durability with 80 ShA hardness: The NBR 80 ShA compound offers better wear and pressure resistance compared to softer grades, while maintaining enough flexibility for static sealing applications.

• Designed for industrial sealing in hydraulics & pneumatics: This O-Ring is tailored for use as an effective seal in hydraulic cylinders, pneumatic valves, fluid connectors or industrial assemblies, delivering performance where reliability counts.

• Metric large-diameter format (122 x 3,55 mm): Ideal for installations where bespoke or non-standard seal sizes are required, supporting application designs with large gland bores or retrofits.

• Robust rubber gasket material for industrial media: NBR is widely used in sealing solutions against oils, greases and hydraulic fluids. With 80 ShA hardness, this ring improves resistance to compression set and ensures stable performance.

FAQ

Q1: What does “80 ShA” signify for this O-Ring?
A: The “80 ShA” refers to the hardness rating of the elastomer compound (Shore A scale). At 80 ShA, the material offers a balance between flexibility and rigidity, suitable for industrial seals where durability and compression resistance are both important.

Q2: Is NBR 80 ShA suitable for use in hydraulic oil systems and greases?
A: Yes. Nitrile rubber (NBR) is commonly used for rubber gaskets and sealing rings in hydraulic and pneumatic applications because of its compatibility with mineral oils, greases and industrial fluids.

Q3: Can this O-Ring be used in dynamic applications with motion?
A: This model is primarily optimized for static sealing or light dynamic conditions. For high-velocity motion or heavy reciprocation, you should ensure the gland design is correct, and consider specialised materials if needed.

Q4: How to verify that the size 122 x 3.55 mm fits correctly?
A: Measure the gland or groove inner diameter and ensure the cross-section matches 3.55 mm. Correct sizing is critical to proper compression, minimal leakage and long service life of the seal.

Q5: How fast can we get this product and is it stocked?
A: Yes — the product is available at our warehouse in Lublin (ul. Smoluchowskiego 1, building 4) and is eligible for 24 h delivery. Ideal for maintenance spares, procurement and rapid dispatch for industrial operations.
