VEE SETS METRIC

DESCRIPTION

Our MVS metric vee packing sets consist of neofab fabric-reinforced nitrile (neofab) vees only or a combination of neofab and nitrile vees. The male and female adapters are typically nylon or polyacetal to provide high structural strength and as bearing surfaces in demanding applications. 

These parts are 'stacked' together and must be lubricated liberally with clean operating fluid prior to assembly. The packing must be axially pre-loaded by the housing. This pre-loading works through the male adaptor on the pressure side by exerting a hinging action on the vees, which forces the sealing lips apart to ensure a low pressure seal. As the pressure increases, so the hinging action increases, increasing the effectiveness of the seal even where severe vibration, shock loading and knuckling may occur.
