Real Seal is known as one of the top polyurethane seal and component product producers, with strong materials and extensive product expertise. Polyurethane is the material of choice to create longevity in products due to its resistance to abrasion and performance in punishing environments. It is an excellent engineering material, and can be formulated to meet a wide range of application specifications. Isocyanate cured with physical properties second to none, these rings are formulated for resistance to high pressure and punishing or highly abrasive environments. Typically called out as "cast" urethane O-rings, these parts perform well in quick disconnects, high pressure hydraulic and water applications, and nail or riveting equipment.
