Vee Packings
American Packing Vee Packings are multiple-lip (chevron) seals
comprised of a group of endless rings and are popular for sealing rods
and pistons. They can be used for low or high pressure applications
and with single or double acting cylinders.
American Packing presently stocks Female and Male Adapters (top
and bottom) in fabric reinforced nitrile and V-Rings (center rings) in
fabric reinforced nitrile and in homogeneous 90 Durometer nitrile.* In
general, fabric Vees are for high pressure, and homogeneous Vees
are for low pressure. The selection of fabric or homogeneous
compounds should be made on the basis of operating pressure,
temperature, and the type of gaseous or fluid medium with which the
packing must function. (*Call for availability of other compounds)
Installation
Properly installed Vee Packings will generally outperform other lip-type seals. They are always installed in sets. Each set
contains a number of V-Rings (based upon the pressure) plus male and female adapters.
The V-Rings in each set are referred to as pressure rings. Refer to the table below to determine the number of V-Rings
per set based on solid rings. This table applies to the majority of installations. There will be exceptions, depending upon
special operating conditions, where the table guidelines do not apply.
Standard Vee Packings use a 90° included angle (commonly referred to as 45°) measured on one side only.
