22X56 - ESAB 125 PSI Brass Relief Valve 3/4-Inch NPT

Protect Your Shop and Equipment with ESAB Reliability

Safety is the number one priority in any welding shop or industrial facility. The ESAB 22X56 Relief Valve acts as the silent guardian of your gas distribution system, ensuring that your expensive regulators, hoses, and flowmeters are never subjected to dangerous over-pressure events. Whether you are running a central gas manifold or a simple station drop, installing a reliable relief valve is a small investment that prevents costly equipment damage and ensures a safe working environment for your team.

Why You Need a 125 PSI Relief Valve

Most welding gas delivery systems operate at pressures well below 125 PSI. However, regulator creep, seat failure, or accidental adjustments can cause line pressure to spike. Without a relief valve, this pressure has nowhere to go, potentially blowing out diaphragms or bursting hoses. The ESAB 22X56 is pre-set to 125 PSI, providing a safety ceiling. If the pressure hits this limit, the valve pops open, vents the excess gas safely, and then snaps shut again, keeping your system secure without requiring manual resetting.

Built for the Long Haul

Constructed from durable, heavy-duty brass, this valve is built to withstand the rigors of daily shop use. It resists rust and corrosion, ensuring that the safety mechanism remains free-moving and ready to act when needed. The 3/4-inch connection is robust and easy to install into standard pipe fittings, making it a versatile choice for upgrading existing manifolds or building new gas lines.

Easy Installation and Peace of Mind

Adding the ESAB 22X56 to your system is straightforward. Simply thread it into a compatible 3/4-inch port on your manifold or pipeline. We recommend using an approved thread sealant compatible with the gas service (such as PTFE tape for inert gases) to ensure a leak-free connection. Once installed, you can focus on your welding projects knowing that your gas supply system has a dedicated safety backup protecting your infrastructure 24/7.
