O-Ring 108x4 NBR

Technical Features & Material Overview

The O-Ring 108x4 NBR 70 Shore is a precision industrial sealing component designed for demanding applications. With an inner diameter of 108 mm and a cross-section thickness of 4 mm, this rubber gasket is manufactured from nitrile rubber (NBR) with a hardness rating of 70 Shore A. This material offers excellent oil and hydraulic fluid resistance, making it ideal as a sealing ring or static seal in heavy-duty hydraulic and pneumatic systems. The 70 Shore A hardness strikes the optimal balance between flexibility and mechanical durability. Typical applications demand high resistance and long life, and this product meets those needs.

Key performance parameters: NBR material enables reliable operation in environments exposed to oils, greases, hydraulic media and common industrial fluids. The standardized 108x4 dimension ensures compatibility with many assemblies and the consistent machining and production heightens sealing reliability. A local warehouse in Lublin, ul. Smoluchowskiego 1, ensures fast logistics and supports procurement agility for B2B clients.

FAQ

Q1: What does the specification “108x4 NBR 70 Shore” mean?
A1: It designates an O-Ring with an inner diameter of 108 mm, a cross-section of 4 mm, made from NBR (nitrile rubber) with a hardness of 70 Shore A. These values reflect physical dimensions and material property of the rubber seal.

Q2: Is this O-Ring appropriate for hydraulic and pneumatic systems?
A2: Yes. The NBR material offers excellent resistance to mineral oils, hydraulic fluids, greases and standard industrial media, making the O-Ring suitable for hydraulic and pneumatic applications. Always verify compatibility with specific fluids, pressures and temperatures.

Q3: What temperature range can this seal support?
A3: Under typical industrial conditions the NBR 70 Shore A version supports operation from about -30 °C up to +100-120 °C, depending on media and system conditions. For higher temperatures or aggressive chemical media, a specialised elastomer may be required.

Q4: Can this O-Ring be used in dynamic‐motion applications?
A4: This sealing ring is designed primarily for static or lightly dynamic applications (small displacements, moderate speed). For highly dynamic motion, large oscillations or extreme conditions, a specialized dynamic seal or alternative material should be considered.

Q5: How quickly can I receive this product and where is it shipped from?
A5: The item is stocked in our warehouse in Lublin at ul. Smoluchowskiego 1. Dispatch is available within 24 hours, ensuring rapid supply for industrial maintenance and procurement teams.
