Project Description

Grade RM 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 or inert gas(such as argon gas and helium gas etc.)welding,in line with the requirements of standard RMA/CGA for Grade RM welding hose,non-conducting;the inner layer of rubber hose of this grade i not oil and flame resistant,but the protective layer is oil and flame resistant.
1. Inner layer of hose:styrene butadiene rubber (SBR) that is applied to oxygen and acetylene gas;
2. Protective layer of hose:=nitrile-butadiene rubber and butyronitrile polyvinyl chloride blends(NBR & PVC) or chloroprene rubber(CR)
3. Intermediate reinforced layer:polyester fiber spiral line.
Applicable temperature: -25℃ to 70℃。



Most of our rubber material imported from foreign countries( South Korea LG, Malaysia) Some bought from domestic market such as Sinopec China.
