INNOVATIVE ENGINEERING FOR CORROSION PROTECTION

Unlike Xylan® coated isolation washers, the new Diamond-Hyde™ HCS Washersare much more abrasion resistant and stronger dielectrically than the oldergeneration isolation washers. Long life and superior electrical performanceare dependent upon an impermeable, electrically resistant coating. Diamond-Hyde™ HCS Washers provide both with the addition of a very chemically resistantbarrier.

The isolating washer can be the weakest link in a flange isolating kit. By usingDiamond-Hyde™ HCS Washers, the washer is virtually impervious to cracking,chipping or scratching. The Diamond-Hyde™ HCS Washer has passed API 6FBfire testing.
