PQ2 seal is composed of four parts: a part in PTFE + BRONZE which constitutes the structure of the seal, an x-ring that guarantees the external sealing and two o-rings which have the function of energizing the seal.
This is a double-acting seal for hydraulic cylinders. The temperatures and chemical compatibility depend on the material of the orings or x-rings.
it's a seal with reduced radial dimensions when the absolute separation of two fluids is required, mainly in oil / gas systems.
It is recommended to combine this seal with at least 2 guide rings for cylinders with a long stroke and at least 1 guide ring for short strokes.
GENERAL CHARACTERISTICS
- High sealing action in applications requiring fluids
separation, e.g. fluid / fluid or fluid / gas.
- Double safety thanks to the combination of low friction materials
with elastomer seals.
- High operating pressures, higher sliding speed.
- Excellent sliding properties, no stick-slip effect.
- Wide range of sizes.
APPLICATIONS
- Presses
- Hydraulic stabilizing legs
- Mobile hydraulics
- Heavy suspension cylinders
- Heavy shock absorbers
- Medium separation of fluid / fluid or fluid / gas; note that one of the two agents must be a lubricant.
