Material Notes:
Yellow/Green Polyurethane Rubber, 50-60 °IRHD. ASTM & ISO designation = AU.Applications: Good abrasion resistance and tensile strength, with fluid compatibility approaching that of NBR. Polyurethane seals provide outstanding performance in hydraulic systems which are prone to abrasive contamination and high shock loads. Good resistance to weathering and ozone but poor against water and high temperature. Good radiation resistance.
