HNBR 90 O-Rings (Hydrogenated Nitrile)
HNBR 90 o-rings are produced from the hydrogenation of Nitrile, resulting in varying degrees of saturation of the polymeric chain, along with a range of enhanced physical strength and chemical resistance properties.

HNBR o-rings are ideal for all oil resistant applications, including exposure to such oil additives as detergents, anti-oxidants and anti-wear agents.
• Exposure to oil soured with metal sludge.
• Seals for oil well applications.
• Seals for automotive fuel handling systems.
• Seals for general industrial usage.
