In February 2020, a Chesterton specialist recommended installing 6 Chesterton® 1600 Graphite Valve Packing without the need to replace the stem or valve.

This graphite valve packing features advanced construction for superior leakage control and high integrity:

• Layers of graphite tape are applied into compact strands
• Each strand is reinforced with an Inconel®* wire mesh covering
• Strands are square plait braided to form a dense pliable packing and further enhanced with blocking agents
• The packing’s exterior is densely coated with lubricating agents to reduce stem friction
• A passive corrosion inhibitor is applied to prevent valve stem pitting
