HNBR O-Rings

HNBR O-Rings (Hydrogenated Nitrile Rubber seals)

HNBR 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, also known as Highly Saturated Nitrile (HSN), is a synthetic polymer 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.

Key Uses

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.
