HYDRAULIC AND PNEUMATIC SEALING: Chevrons
Sealing solutions suitable for heavy, low-speed hydraulics where dirt and wear problems arise, such as injection machines, presses or cylinders in mining and earthmoving machinery. They can even be used on poorly finished piston and rod surfaces.
A chevron packing is the combination of several elements, V-shaped profiles, which form a single package: a base or seat ring (female); several intermediate rings and a cover or closure ring (male).
The constructive designs are nitrile (NBR) or fluorinated rubber (FPM) elastomers, reinforced with fabric.
For chemically aggressive media, we recommend PTFE or PTFE seals with fillers and bottom/cover rings made of thermoplastic materials or even bronze.
