Supranite Packing 557

Expanded graphite braided packing for valves, reinforced by Inconel ® wires in a specific structure that limits friction and improves the sealing performance.

SUPRANITE ® PACKING 557 is an expanded graphite braided packing for valves, reinforced by Inconel ® wires in a specific structure that limits friction and improves the seal.
The low-sulphur graphite quality (<300ppm) of SUPRANITE ® PACKING 557 inhibits corrosion.
The particular structure of SUPRANITE ® PACKING 557 allows its use alone as a complete sealing set of rings or just as top and bottom rings with SUPRANITE ® NGN 02 AS moulded rings.
Ease of cutting of the rings whatever their cross section.
