HNBR seals are made of hydrogenated nitrile-butyl rubber, which has excellent resistance to high temperatures (-30°C to +150°C), oils, fuels and abrasion. This makes them more suitable for use in higher temperature environments than conventional NBR (nitrile-butyl rubber). HNBR is particularly suitable for demanding applications such as automotive and industrial systems, where extreme temperature fluctuations and harsh chemical environments must be dealt with.
The KTT oil seals are carefully manufactured, thoroughly inspected, reliable, high-quality radial shaft seals.
