Vee Packing Seals for Cylinder

Seals need to be made to have options in clearances if your going over or thru threaded surfaces or sharp projections. The clearance level needs to be made for the least amount tolerance in order for it to do it’s job. For every one thousandth of an inch that is added to the clearance that goes between the seal and the surface that it is sealing takes away the survival of the packing.

The correct schematic is vitally important when you are using sets of seals on the piston of double acting cylinder. Like in Dia. 1 where you have a female adapter that is movable which makes the load to have a direct response to relocate the the set of other seals after pressure has been utilized to the other side. Which it will be begin to have friction and wear on the seals.

In Dia. 2 it is not correct either in that it shows the pressure is closed in between the set of packings.
