Chesterton 1622 Low E Valve Packing
Low Emissions Packing for Isolation Valves


​​Our award-winning 1622 Low E Packing minimizes block (isolation) valve VOC emissions. It exceeds current emissions requirements for the refinery, petrochemical, and chemical industries.

This is a non-hardening, flexible packing constructed from an Inconel-reinforced mesh with internal exfoliated graphite, which keeps it from shrinking or absorbing moisture. 1622 contains a passive corrosion-inhibitor to prevent galvanic corrosion of valve parts in contact with the packing.
