Which sizes is suitable for your market?
GB2Â (JIS G3448)
Standard pipe length is 6m. Other lengths and specifications can be customized according to correspondents' needs.
Sealing ring material:
Option 1. CIIR(Chlorinated butyl rubber):Â 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) :Â 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):Â 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:Â we pack press fittings in polybag to prevent surface scratch, and then pack them inside brown export cartons.
For pipe packing:Â 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.
* Free sample:Â we can provide a few free sample for evaluation.
* After-sales service:Â we provide after-sales technical support for clients.
* Strict Quality control:Â we have 100% inspection before delivery to ensure every pieces are in good quality.
