The rod sealing set Praedifa series M0 consists of several chevrons. Profile MX is the fabric-reinforced chevron version, Profile MG are chevrons made of NBR-based rubber material. These chevrons are installed together with a plastic or hard fabric back-up ring (profile MD) and a hard fabric header ring (profile MS). The chevrons are manufactured with radial preload which provides close contact of the sealing lips with the inside and the outside diameters, thus achieving good sealing performance. The operating pressure will provide a close fit between the chevrons and the mating surfaces. An optimum adaption of the relative friction to tightness may be achieved by an adjustable housing (screw rings or shims). Due to this adjustment facility it is possible to achieve a longer working life for the sealing sets.

• Robust seal profile for harshest operating conditions.
• Insensitive to contamination of the operating medium or slight damage of the sliding surfaces compared with single-part seals.
• The seals can also be cut for installation, which eliminates the need for complete dismantling of the cylinder during maintenance or repair work.
• Insensitive to pressure peaks.
• High extrusion resistance.
• Excellent media resistance in case of suitable compound selection.
• Enables modifications of axial preload and/or readjustment by means of metal spacers (shims or screw rings).

Range of application
Mainly used in heavy duty cylinders with large diameter, and also in actuators for weir applications.
