Gland Packing Chesterton 329

Specification of Gland Packing Chesterton 329

Stern-Lon™ Flax Packing
Chesterton 329 is square-plait braided to provide an unusually flexible, formable
packing. The base fiber in Stern-Lon is a long-fibered, roved flax of the highest
quality. The packing is graphite-free to avoid galvanic corrosion on shafts. 329
is first impregnated with concentrated PTFE dispersion to promote non-flowing
lubricity and to retard degradation.
