Description

Flexible Oil & Fuel Resistant Rubber for Sealing Applications

Soft Nitrile 45 Rubber Sheet is a premium-grade NBR (Nitrile) rubber manufactured by Reglin, engineered for applications requiring excellent oil and fuel resistance combined with
high flexibility and compressibility.

With a hardness of 45 Duro, this material is softer than standard nitrile grades, allowing it to conform to uneven surfaces, making it ideal for gaskets, sealing, and oil-exposed applications.

Designed for Oil and Fuel Exposure

SEC Business Group supplies Reglin nitrile rubber solutions for industrial, mining, and maintenance environments.
