IMPORTANT NOTE: Grade “R” welding hose is for use with acetylene only as specified by the RMA-CGA Hose Standard.
“T” Grade hose must be used with all other gases.
WARNING: Do not exceed the maximum working pressures (regulator setting) listed for the hoses
during welding and cutting operations.

In-Service Caution: The user is first cautioned to shut off the gases at the torch and then at the regulators or supply source
when the torch will not be used for periods in excess of 30 minutes in order to limit permeation of gas through the hose wall.
