Parker Standard B7 type piston seal is a kind of lip seal installed in the groove as a tight fit. B7 Type seal can be used in various occasions where the physical properties of ordinary rubber or fabric reinforced rubber cannot meet the requirements.
The main advantages of this seal are:
1. Excellent abrasion resistance.
2. Anti-extrusion.
3. Impact resistance.
4. Small compression deformation.
5. Adapt to the harshest working conditions.
6. Easy to install.
Application range:
Working pressure: ≤400bar
Operating temperature: -35 to +120°C
Surface speed: ≤2m/s
Medium: hydraulic oil
Mainly used for heavy-duty mobile machinery and piston seals in static pressure.
Installation of Parker Standard B7 Type Piston Special Hydraulic Seals:
This type of seal should have an axial clearance. To avoid damage to the sealing lip, do not pull the seal on sharp edges during installation. This type of seal usually fits into a closed groove. When access is restricted, special installation tools may be required.
