Piston Seal OQ Profile

Piston Seal OQ Profile


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 two piece design comprised of a standard size O-ring energizing a wear resistant PTFE cap. The OQ profile offers long wear and low friction, without stickslip. 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. Parker’s OQ profile will retrofit non-Parker seals of similar design.


The OQ profile may be ordered without the energizer by omitting the energizer code. See part number nomenclature in the downloadable PDF.
