Red Fiber Spiral Flexible Refrigerant Hose With Inner Diameter Size 5mm

Three Colors Refrigrant Charging Hose With Inner Diameter Size 5mm

Performance:

Anti-ozone aging: in the standard test chamber, concentration: 50+/-pphm; temperature: 40+/-2℃; testing period: 72t; without crack.

Heat-proof aging: in the standard aging chamber, temperature: 70+/-℃; testing period: 72t; tensile change: not more than -25%; tensile stretch: not more than -30%.

Physical properties: tensile stretch of inner and outer rubber layer:>300%; flexiblity of hose is sound under -30+/2℃ for 5t; without craze crack or fracture after 180 bending over or doubling.

Corrosion resistance: the oil resistant grade of inner rubber layer is RMA-B; hexane corrosion resistant; preventing seepage of various refrigerants.

Scope of application:

Conveying refrigerant such as R12, R22, R502 and R134a; applied widely to auto refrigeration, air-conditioning, industrial refrigerators etc; both the inner rubber layer and protective layer are of high level oil resistance of grade RMA-A antiseepage.

Package:

See the table for available common specifications, pressure, weight, length and volume etc;

Standard dual protective packaging: transparent OPP films intertwined inner layer; braided spiraled outer layer;

In addition, the carton packing and pallet packing are available as the case may be, but shall be changed additionally.

1. The stable for detailed standard parameters:

Structure:

Inner layer of hose: High nitrile-butadiene rubber (NBR)

Protective layer of hose: NBR&PVC blends

Intermediate reinforced layer of hose: polyester fiber sprial line.

Colors: 

For refrigerant charging hose, there are regular three colors: red, blue and yellow. These three colors refrogerant hoses are usually used together to transporting refrigerant R12, R22, R502, R134a etc.
