Master Pro Series Premium Quality 50-foot Acetylene / Oxygen Torch Hose Twin Pack. A durable flexible twin hose set designed for transporting oxygen and acetylene gases to your welding torch brazing soldering and cutting equipment. These R-grade long-lasting hoses are ideal to use while working on all of your metalworking projects. Both the oxygen hose and acetylene gas hose have a 1/4-inch (6.3mm) (ID) inner diameter and a 1/2-inch (13mm) (OD) outer diameter and have a maximum pressure of 300 PSI (20 Bar) to supply an optimal flow rate. The hose set has a color-coding system so you can distinguish that the green hose is for oxygen and the red hose is for acetylene and this will ensure safe and accurate connections to your regulator and oxy torch. All four hose ends of the twin welding hose set come with standard size B threaded fittings. The fitting sizes are 9/16 -18 LH left-hand thread for the red acetylene hose and 9/16 -18 RH right-hand thread for the green oxygen hose which enables the hoses to connect onto existing standard regulators and torches. The 50-foot (7.6m) long torch hoses enable you to safely keep the tanks away from the torch tip while in use. The welding hoses are long enough for mechanics shops production line welding and other indoor and outdoor construction industrial and agriculture uses. Our durable flame retardant flexible twin welding hoses are fused together and are resistant to kinking cracking abrasion and weather unlike other hose sets that easily crack or leak creating a fire hazard. They stay flexible in extreme temperatures from -4°F to 158°F making them ideal for long-term use. Six zip ties included.
