Double Delta

The Double Delta is a double-acting sealing element which is energized by an elastomer O-Ring. The Double Delta seal can be fitted in existing O-Ring grooves (US standard AS 568 A, MIL-P-5514) and it demonstrates good friction properties, stick-slip-free starting and excellent dry-running. The Double Delta is used in light and medium-duty industrial hydraulics.
