V-Packings, WV-Packings

Both the V-packing and WV-packing are multiple-lip hydraulic seals that are made up of many v-ring seals stacked upon one another. The top and bottom of the V-packing or WV-packing are called the male adapter and female adapter separately.

Also known as chevron packing, this series of industrial seal set offers extra stability as it contains multiple V-ring seals. If one seal in a set fails, there will be another seal to serve as back-up.

Due to its excellent rigidity, extended service life, and superior sealing performance, this multi-lip seal has become a customer favorite. One the most popular uses is in the oil cylinder of a hydrostatic pressure tester.

Groove dimensions in the above table are determined based on a typical polyurethane vee packing that contains 3 v-ring seals, as marked in green in the product dimensions diagram. Customer can either increase or reduce the number of the V-ring seals needed in a specific application according to the pressure of hydraulic cylinder. Watch out also for the height of modified groove. For details,Please refer to our handbook.
