Is the Flat gasket for STORZ firefighter connectors, white NBR rubber resistant to fuels or hydraulic oils, and what precautions are recommended if exposed?

Flat gasket for STORZ firefighter connectors, white NBR rubber has only limited resistance to greases and oils. White NBR (nitrile rubber) offers good resistance to many mineral oils and fuels but performance depends on type, temperature and exposure time. It may resist short, incidental contact with fuels or hydraulic oils at typical service temperatures (within -40Â°C to +110Â°C), but prolonged immersion, high temperatures near the upper limit, aggressive fuels or certain hydraulic fluids (with additives or synthetic bases) can cause swelling, softening, loss of sealing properties and shortened life. Recommended precautions if exposed: - Avoid prolonged or continuous contact with fuels or hydraulic oils; use only for incidental exposure. - Inspect gaskets frequently after exposure for swelling, cracking, hardening or loss of elasticity. - Replace the gasket immediately if any deterioration is observed. - Where sustained exposure to fuels or aggressive hydraulic fluids is expected, select a gasket material with higher chemical compatibility (e.g., FKM/Viton or specialized fluoroelastomers) and consult material compatibility data. - Clean surfaces promptly after contamination using compatible solvents; ensure gasket is dry before reassembly. If application involves critical safety or continuous oil/fuel contact, verify compatibility with the fluid manufacturer or choose a more resistant material rather than relying on Flat gasket for STORZ firefighter connectors, white NBR rubber.

Can the Flat gasket for STORZ firefighter connectors, white NBR rubber withstand prolonged exposure to petrol, diesel, or hydraulic fluids?

Flat gasket for STORZ firefighter connectors, white NBR rubber: No - it has only limited resistance to greases and oils, so it is not suitable for prolonged exposure to petrol, diesel, or hydraulic fluids. Short incidental contact may be tolerated within its chemical limits and temperature range (â40Â°C to +110Â°C), but continuous immersion or long-term exposure will likely cause swelling, degradation and loss of sealing performance. For applications with fuel or hydraulic fluids, choose a gasket material specifically rated for those hydrocarbons (e.g., FKM/Viton or specialized NBR grades) and verify compatibility with the specific fluid.

Does the Flat gasket for STORZ firefighter connectors, white NBR rubber resist common household lubricants or oils?

Flat gasket for STORZ firefighter connectors, white NBR rubber has limited resistance to greases and oils. This means it can tolerate some common household lubricants and oils for short periods or incidental contact, but prolonged exposure or contact with strong mineral oils, solvents, petroleum-based lubricants, or aggressive chemicals may cause swelling, softening, loss of elasticity or premature failure. NBR (nitrile rubber) generally resists water, hydraulic fluids and some oils, but its performance depends on oil type, concentration, temperature and duration of exposure. Operating temperature range is â40Â°C to +110Â°C; higher temperatures accelerate degradation when oils are present. For reliable service in applications with frequent or heavy oil/lubricant exposure, consider confirming compatibility with the specific lubricant manufacturer or using a gasket material with higher oil resistance.
