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.

- API 622, 2nd edition tested and qualified
- VDI 2440 (TA-Luft) approved
- API 624 tested and qualified for numerous valve OEMs
