G422 Grade R Twin Weld Hose
Grade R Twin Weld is designed for welding and cutting where oxygen and acetylene are used. Grade R is by far the most commonly used welding hose today. However G422 is not suitable for use with other fuel gas mixtures that have appeared in recent years. These hydrocarbon based fuel gases require a low-permeation, oil resistant hose (inquire for G423.)
