The Parker OQ profile is a bi-directional piston seal for use in low to medium duty rotary or oscillating applications. The OQ profile is a simple two piece design comprised of a standard size Parker O-ring energizing a wear resistant PTFE cap. The OQ profile offers long wear, low friction and no slipstick. The PTFE inner diameter is designed with a special interference with the O-ring to eliminate spinning between the O-ring and seal. Special grooves are designed into the PTFE outer diameter to provide lubrication and create a labyrinth effect for reduced leakage. The seal is commonly used in applications such as mobile hydraulics, machine tools, injection molding machines and hydraulic presses. Parker's OQ profile is designed to retrofit non-Parker seals of similar design.  Narrow profiles feature single groove (shown).  Larger profiles feature dual OD grooves.
