Is the NBR KGWU Type Seal for Railway Nut suitable for use in temperatures from -20°C to +70°C and resistant to oils and wear?

Yes. The NBR KGWU Type Seal for Railway Nut is suitable for use from −20°C to +70°C and is resistant to oils and wear. Made from durable NBR, it maintains flexibility and sealing properties across that temperature range and offers excellent resistance to oils, environmental factors, and mechanical wear, ensuring long‑lasting performance for KGW railway nuts.

Can the NBR KGWU Type Seal for Railway Nut withstand prolonged outdoor exposure and routine cleaning with industrial lubricants without degrading?

Yes. The NBR KGWU Type Seal for Railway Nut is formulated from durable nitrile rubber (NBR) specifically to withstand the harsh demands of rail applications. Its material properties give strong resistance to wear, oils and environmental factors, so prolonged outdoor exposure will not significantly degrade its sealing performance within the specified service temperature range (‑20°C to +70°C). The seal’s oil resistance also makes it compatible with routine cleaning and incidental contact with common industrial lubricants used in rail maintenance, preserving flexibility and sealing integrity under normal maintenance practices. For best longevity, avoid prolonged immersion in aggressive solvents or exposure above the stated temperature limits; under typical field conditions and standard lubricant cleaning, the seal remains a reliable, long‑lasting solution.
