DDKK combined seal - GDKK combined seal - GD1000K piston seal
1. Standard materials
Guide ring: nylon PA or filled PTFE F-PTFE
Retaining ring: nylon PA or filled with polytetrafluoroethylene F-PTFE
Sealing ring: filled with PTFE F-PTFE
Elastic ring: Nitrile rubber NBR or fluororubber FKM
2. Application scope
It is composed of a sealing ring, an elastic ring, two retaining rings, and two guide sleeves. The guide sleeve plays a positioning and guiding role, while the elastic ring provides pre tightening force and compensates for the wear of the sealing ring. The sealing ring forms a matching dual surface with the inner hole of the oil cylinder to produce a sealing effect, suitable for sealing oil cylinder pistons. DDKK has a bidirectional sealing effect.
When designing and selecting, reference can be made to Hunger's GD1000K series standards.
