O-Ring 14x1.5 NBR

Applications of the 14x1.5 NBR O-Ring

The O-Ring 14x1.5 NBR 70 Shore is a standard sealing ring used for creating reliable static and light dynamic seals in industrial and automotive systems. It is widely applied in hydraulics, pneumatics, fuel systems, machinery maintenance, compressors, pumps, valves, and service equipment.
Its resistance to oils and hydraulic fluids makes it a preferred seal for workshop and industrial environments.

Advantages of NBR 70 Shore Material

NBR (Nitrile Butadiene Rubber) with a hardness of 70 Shore A is the most commonly used elastomer for oil seals due to its balance of flexibility and chemical resistance.

Key benefits:

• Excellent resistance to oils, fuels, and greases

• Good mechanical strength and abrasion resistance

• Stable sealing performance under pressure

• Temperature operating range: -30°C to +100°C (short peaks up to 120°C)

• Suitable for industrial and automotive sealing applications

This ensures the 14x1.5 NBR O-ring provides long service life and reliable sealing performance in a wide range of operating conditions.

FAQ - Frequently Asked Questions

1. Is NBR suitable for hot water or steam?
No. For hot water or steam applications, EPDM or FKM/Viton® is recommended.

2. Can this O-ring be used in hydraulic systems?
Yes, NBR is ideal for hydraulic oil-based systems.

3. Is 70 Shore A a universal hardness?
Yes, 70 Shore A is the standard hardness, offering a balance between flexibility and sealing force.

4. How do I choose the correct O-ring size?
Match the inner diameter and cross-section to the groove dimensions and media compatibility.
