Welders, listen up! This Boltigen 50-foot oxygen acetylene hose is built tough for your welding and cutting jobs. It's a twin hose - green line for oxygen, red line for acetylene, so you won't mix them up. Made from Grade R rubber with a 1/4-inch inner diameter, it handles max working pressure of 300 PSI (burst pressure is 900 PSI, so it's safe). Both ends have brass B fittings: 9/16\-18LH for acetylene and 9/16\-18RH for oxygen, plus stainless steel spring guards to prevent kinks and protect the ends when bending. The 50-foot length gives you plenty of reach around the shop. Durable, flexible, and color-coded for safety. Whether you're running a torch for cutting or welding, this hose delivers consistent gas flow and stands up to shop abuse. A solid upgrade or replacement hose that gets the job done.
