HNBR 70 O-Rings (Hydrogenated Nitrile Rubber seals)
HNBR 70 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 70 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.
HNBR O-Rings are ideal for mechanically demanding applications. Heat and Chemical resistant. Available in BS / Metric sizes.
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.
