Uni-rings seals are a one pc. double acting piston seal made from 2 different durometers of urethane bonded together. The outer surface is impregnated with molybdenum disulfide (for decreasing friction) and contains a groove to hold lubricant. Some of these seals will retrofit into T-seal and wide base T-seal grooves.
