Sealing ring material:
Option 1. CIIR(Chlorinated butyl rubber): Sanitary for human consumption, not oil resistant. Suitable for drinking water, tap water, hot and cold water, sanitary air.
Option 2. EPDM(Ethylene-Propylene-Diene Monomer) : Sanitary for human consumer, not oil resistant. Suitable for drinking water, tap water, hot and cold water, sanitary air and compressed gas.
Option 3: FKM(Fluororubber): It is both oil proof and sanitary. suitable for edible oil, compressed air. But a little more expensive than CIIR, EPDM and NBR.

Packaging & Shipping
For press fittings packing: we pack press fittings in polybag to prevent surface scratch, and then pack them inside brown export cartons.
For pipe packing: we pack the stainless steel pipes inside polybag, so that it can prevent surface scratch, and keep dirts away from the inside of the pipes.
If you have special requirement on packing, please tell us.
