1622 Isolation Valve Packing

Low Emissions Packing for Isolation Valves

Chesterton 1622 is an award-winning packing that seals VOC emissions in isolation (block) valves to below 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.
