Phenolic wear rings are designed with tubing made from fine weave cotton fabric wound on molds and imbued with phenolic resin. Wear bands have 110 Rockwell hardness and withstand temperatures to 250° C. They suit most hydraulic fluids, including oil and water, water and glycol, phosphate ester, silicone oil, brake fluid, and torque converter oil. They maintain high dimensional stability and abrasion resistance.
