INDUSTRIAL HYDRAULIC SEALS

Billets / Slabs

Nitrile Elastomer NBR hardness 85 (Nitrile Butadiene Rubber). Used for general applications and resistant to mineral oils, HFC, and cold water. Can be used to manufacture hydraulic rod and piston seals, wipers, radial and static seals. The material comes with a small orange resin coating which is removed during CNC machining. The purpose of this coating is to increase material firmness during machining and prevent deformation during storage.
