Is the STORZ firefighter connector gasket for suction and discharge hoses, black NBR rubber, suitable for use with petroleum-based oils and greases?

The STORZ firefighter connector gasket for suction and discharge hoses, black NBR rubber, has limited resistance to greases and oils. NBR (nitrile rubber) generally resists petroleum-based oils and greases better than many elastomers, but "limited resistance" indicates it is not ideal for continuous or heavy exposure. For occasional contact or short-term use with petroleum oils/greases within the temperature range -40Â°C to +110Â°C it may be acceptable; for prolonged immersion, high concentrations, aggressive hydrocarbons or elevated temperatures near the upper limit, performance, swelling and accelerated degradation are likely. If service involves frequent exposure to petroleum-based fluids, choose a gasket material with proven high hydrocarbon resistance (e.g., FKM/Viton or specialized compounds) or consult the manufacturer for compatibility data.

Can the STORZ firefighter connector gasket for suction and discharge hoses, black NBR rubber, withstand continuous exposure to hydraulic oils and greases?

STORZ firefighter connector gasket for suction and discharge hoses, black NBR rubber offers limited resistance to greases and oils. It can tolerate incidental or shortâterm contact with hydraulic oils and greases, but it is not recommended for continuous, prolonged exposure to aggressive hydraulic fluids. Continuous contact may cause swelling, hardening or loss of sealing properties over time. If constant exposure to hydraulic oils/greases is expected, consider selecting a gasket material with higher oil resistance (e.g., FKM/Viton) or consult the manufacturer for chemical compatibility and service-life guidance.

Does the STORZ firefighter connector gasket for suction and discharge hoses, black NBR rubber, resist brief contact with mineral oils?

Yes. The STORZ firefighter connector gasket for suction and discharge hoses, black NBR rubber, offers limited resistance to greases and mineral oils, so it will resist brief contact with mineral oils. However, prolonged or continuous exposureâespecially to aggressive oils, high temperatures, or strong solventsâcan accelerate degradation (swelling, softening, loss of mechanical properties). Use it for short-term or incidental contact with mineral oils, but avoid sustained immersion or repeated long-term exposure.
