Project Description

GRADE R WELDING HOSE

GRADE R WELDING HOSE

Sizes: 3/16″, 1/4″, 5/16″, 3/8″, 3/16″, 1/4″, 5/16″, 3/8″
Scope of application:oxygen/acetylene gas welding:insert gas(such as argon gas and helium gas etc.) welding is also compatible;in line with the requirements of standards RMA/CGA for Grade R welding hose, non-conducting;neither the inner layer nor protective layer of rubber hose of this grade are oil and flame resistant.
Structure:
1.Inner layer of hose:styrene butadiene rubber (SBR)
2. Potective layer of hose: blends of styrene butadiene rubber and ethylene-propylene-dien monomer rubber(SBR &EPDM)
3. Intermediate reinforced layer:polyester fiber spiral line.
Applicable temperature:-25℃ to 70℃。

GRADE R WELDING HOSE

Material
