Single acting NBR rod seal incorporating a Polyester anti-extrusion header & POM anti-extrusion rings.
- Design -
Claron Style PDS rod seal is a 3 piece assembly consisting of a Nitrile Rubber sealing element which is backed up by a tough Thermoplastic elastomer header complete with an Acetal anti-extrusion ring on the I.D. The complete assembly forms a highly robust sealing unit for use in high pressure applications where shock loads and pressure spikes are present.
This seal is widely used in the mobile plant industry and is also a modern replacement for common veepac seals.
