SCS offers material advantages of with our family of urethanes in standard o-ring sizes. The high extrusion resistance and related compounds eliminates the need for a back-up in many hydraulic applications, thereby simplifying installation and reducing groove width. Our unmatched temperature rating makes it suitable in applications where other urethanes fail. In addition, Our O-rings provides superior water resistance and compression set resistance in water-based fluids. Premium urethane o-rings are much less prone to spiral failure and installation damage compared with rubber o-rings. Dimensions and tolerances of our o-rings match up with AS568B specifications for diameter and cross-section and are used in the same grooves. 90D = 90 Durometer B = Bulk (Min Quantities) V = Viton (Fluorocarbon) T = 55-58 Shore D PTFE U = 90A Urethane V-BLACK = Black Viton (Fluorocarbon) EP = Ethylene Propylene S = Silicone -
