Welders and metalworkers, this Owfeel quick connect set makes switching between oxygen and fuel hoses way faster and safer. The set includes high-quality brass and stainless steel couplers designed with a quick-connect mechanism – just push to connect, pull to disconnect. They've got a built-in safety feature that prevents gas backflow when disconnected, so no nasty surprises. Max working pressure is 28 PSI for fuel and 142 PSI for oxygen (don't exceed that!). They fit standard 9/16\ attachments and are compatible with most oxy-fuel tools and hoses. The oxygen and fuel connectors are keyed differently so you can't mix them up – a big safety plus. Saves you time twisting fittings, reduces wear on your hoses, and keeps your workspace organized. Whether you're in a shop or on a job site, these are a handy upgrade. Comes with everything you need to set up a quick-disconnect system. Just follow the pressure limits and you're good to go.
