Adjustable
Packing Gland
In the manufacturing process of Webstone Ball Valves, a PTFE stem seal is used to seal between the shaft of the handle stem and
the valve body. This seal is then compressed around the stem by means of a packing gland, which forms a watertight seal around
the handle stem assembly.

Over time, due to various environmental conditions, the PTFE material may expand or contract; thereby affecting the quality of this
seal. To combat this, the majority of the packing glands on Webstone’s Ball Valves are adjustable. If a leak should occur, you may
adjust the packing gland by tightening it slightly in a clockwise manner as illustrated below. If the leak persists, please contact
Webstone Technical Support at (800) 225-9529.

Replace and secure nut.
