Technical Features & Material Overview

The O-Ring 118x4 NBR 70 Shore is a precision-engineered sealing component designed for demanding industrial applications. With an inner diameter of 118 mm and a cross-section thickness of 4 mm, this rubber gasket is manufactured from nitrile rubber (NBR) with a hardness of 70 Shore A. The compound is widely used for its durability, chemical resistance and suitability for static and lightly dynamic sealing tasks. NBR material offers excellent resistance to mineral oils, greases, hydraulic fluids and other common media in industrial hydraulics and pneumatics. The 70 Shore A hardness provides an optimized balance between flexibility and mechanical strength, ensuring the sealing ring will perform reliably under typical service conditions.

Typical application temperature ranges for NBR 70 Shore A rubber O-rings extend approximately from -30 °C up to +100 - 120 °C depending on system conditions and fluid types. This makes the O-Ring suitable for a wide range of industrial sealing scenarios. The fact that this product is available for immediate dispatch from our warehouse in Lublin (ul. Smoluchowskiego 1, building 4) with 24h delivery reinforces its suitability for B2B procurement of critical sealing components.

Industrial Applications & B2B Procurement Advantages

This industrial sealing ring is engineered to serve maintenance engineers, technical buyers, machine manufacturers and distributors of sealing solutions. Key use cases include hydraulic cylinders, valves, pump housings, pneumatic actuators and machinery requiring effective rubber seals in medium to large diameters. The dimension 118x4 mm is commonly requested in the field, and the ready-stock availability avoids long lead times.

Benefits to the B2B customer include:

• Standardised dimension (118x4 mm) simplifies stock management and reduces special-order requirements.

• High resistance rubber gasket (NBR 70 Shore A) means fewer replacements, reduced downtime and lower total cost of ownership.

FAQ

Q1: What does the specification “118x4 NBR 70 Shore” mean?
A1: It indicates an O-Ring whose inner diameter is 118 mm and whose cross-section (thickness) is 4 mm. It is made of nitrile rubber (NBR) with a hardness of 70 Shore A. These parameters determine the correct fit and its sealing performance.

Q2: Is this O-Ring suitable for hydraulic and pneumatic systems?
A2: Yes. The NBR material offers good resistance to mineral oils, hydraulic fluids and greases, making this sealing ring appropriate for hydraulic and pneumatic applications. It fits installations where “uszczelnienia do hydrauliki i pneumatyki” are required. However, always verify compatibility with specific fluids and pressures.

Q3: What temperature range can this seal tolerate?
A3: Under normal conditions for NBR 70 Shore A, the working range is approximately from -30 °C up to +100-120 °C. If higher temperatures, aggressive media or extreme dynamic conditions are involved, a different elastomer may be more suitable.

Q4: Can this O-Ring be used for dynamic motion applications with frequent movement?
A4: This sealing ring is primarily designed for static sealing or slow/mild motion (light dynamic). For high-speed motion, large oscillations or heavy duty dynamic conditions, a dedicated dynamic seal or advanced material may be required.

Q5: What is the availability and delivery schedule?
A5: The item is stocked in the warehouse in Lublin (ul. Smoluchowskiego 1, building 4). It is eligible for dispatch within 24 hours, providing fast replenishment and minimizing downtime for industrial operations.
