Don't Take Chances: Install the Victor V-54/CV-4 Combo

Safety should never be an afterthought when you're working with oxy-fuel torches. The Victor V-54/CV-4 Combo gives you peace of mind by adding a critical layer of protection to your setup. This kit features Victor's trusted CV-4 Check Valves, which are designed to stop gas from flowing the wrong way down your hoses. If a tip gets clogged or a cylinder runs empty, pressure can shift, pushing fuel into your oxygen line (or vice versa). These valves snap shut the moment that happens, preventing dangerous gas mixtures from forming in your equipment.

Installation is quick and easy. These valves screw directly onto the inlet of your torch handle—just like connecting your hoses. They use standard B-Size fittings (9/16"-18), so they fit almost all standard Victor-style torches. The kit comes with one valve for oxygen (green/right-hand thread) and one for fuel (red/left-hand thread), so you can't mix them up. Whether you are cutting thick steel or doing delicate brazing, these high-flow valves won't starve your flame, but they will be there to protect you if things go wrong.

Remember, check valves are your first line of defense against reverse flow. Combine them with flashback arrestors for complete protection. The V-54/CV-4 Combo is an affordable, simple upgrade that every welder should have on their rig. Keep your shop safe and your equipment running right with genuine Victor components.
