O-ring 25x7 NBR

Construction and design

The O-ring 25x7 NBR 70 Shore A is a heavy-duty static sealing solution designed for applications requiring high sealing force and stability under compression. The large 7 mm cross section provides increased contact surface, ensuring superior sealing performance compared to thinner O-rings.

Manufactured from NBR elastomer, this O-ring offers excellent flexibility combined with strong resistance to mechanical stress. It is a widely used material in industrial sealing due to its reliable performance in contact with oils, greases, and fuels.

Industrial applications

The O-ring 25x7 mm is commonly used in:

• static hydraulic systems
• industrial housings and flange connections
• machinery requiring high sealing pressure
• tanks and fluid containment systems
• automotive sealing components

Within the static NBR O-ring category, this model is designed for larger sealing grooves and applications where stronger compression and durability are required.
