Is the Coupling Gasket NOR, NBR Rubber Seal compatible with hydraulic oils and common industrial fluids?

Yes. The Coupling Gasket NOR, NBR Rubber Seal is compatible with hydraulic oils and common industrial fluids. Made from high-quality NBR (nitrile rubber), it offers excellent resistance to oils and a wide range of industrial fluids, providing reliable sealing in such environments. Its robust construction and NOR-standard design ensure a precise fit and durable performance, while the operating temperature range of -10°C to +80°C supports consistent sealing properties in typical hydraulic and industrial conditions.

Can the Coupling Gasket NOR, NBR Rubber Seal maintain its sealing performance at intermittent temperatures below -10°C?

Coupling Gasket NOR, NBR Rubber Seal Format: No. The specified operating temperature range for the Coupling Gasket NOR, NBR Rubber Seal Format is -10°C to +80°C. Intermittent exposure to temperatures below -10°C falls outside this range and may compromise the material’s elasticity and sealing performance. While brief, mild dips slightly below -10°C might not cause immediate failure, repeated or prolonged exposure to colder conditions increases the risk of hardening, cracking, loss of compression set resistance and leakage. For reliable sealing at temperatures below -10°C, choose a gasket material rated for lower temperatures (e.g., suitable fluorocarbon, silicone or specially formulated NBR grades) or consult the manufacturer for a low-temperature variant.
