Our factory has strong quality control team, we set up advanced laboratory.
Before the mass production, we test each batch of raw material
After the production, we test each hose to guarantee a 100% qualification.
Each hose tested at 2 times of working pressure.
We do everything possible to supply good quality goods for our customer.
After finishing the hydraulic rubber hose en856 4sp, we will pack the hose. In general, the packing will
use woven bag and plastic film. Special packing is available according to customers’ requirements.
