Why Choose US
We control the material of PTFE(Teflon) and stainless steel wires per customer's request.
Some are from Japan and Taiwan, some are from China local. Only choose high quality material.
We test leakage of each roll before braiding, then we cut 300mm and crimp it to test
burst pressure after brading.
We use CNC Lathes Machine for end fittings production. Machine system, knife and inspection
tools are all imported from Japan.
We use Techmaflex Crimping Machine which is imported from France. This machine has
accurate and stable performance for crimping because it is produced for PTFE hose crimping only.
