HYDRAULIC AND PNEUMATIC SEALING: Hydraulic rod seals

Collars and seals for installation on the cylinder shaft as individual seals or as secondary seals as part of a combined sealing system.

Constructive designs with symmetrical or asymmetrical lips; with/without support rings to prevent extrusion of the seal in high pressure cylinders and low friction seals consisting of a PTFE ring with fillers and an elastomer to give the seal the required elasticity, usually NBR or FPM.
