DESCRIPTION
The MSMR is a metric multi-lip rod seal designed to meet the needs of hydraulic equipment operating at high pressures and subjected to severe loading and vibration conditions.
The main sealing element is manufactured in a highly compression set resistant nitrile. The most important quality of this element is the design of the multiple sealing lips for maximum sealing efficiency and end face configuration, which ensures that the MSMR can tolerate vibrations and severe misalignment.
The support ring is made in cotton fabric reinforced nitrile elastomer; the “U“ shape is energised when pressure is applied.
The last element is the anti-extrusion ring manufactured in POM.
MSMR is an excellent substitute for metric vee packing (MVS) for most applications.
