Vacuum Hose

Features:
1) Adopts double layers SS metal hose, the interlayer is multi layer insulation    
    compound material, thus can maintain high vacuum status
2) With good cold protection efficiency, the hose surface without sweat and frost 
    when using
3) With small bending radius, simple utilized, and length can be determined by the 
    end users' requirements
4) Can be connected with vacuum pipelines
5) Two ends of vacuum hose is equipped with storage tank and lorry special quick 
    connector, can reduce the liquid vaporization loss during change greatly
