OVERVIEW

Enhance Safety with the ESAB 1/4" NPTF Check Valve

Safety is paramount when working with compressed gases, and the ESAB 21124 Check Valve is a simple yet vital component for your setup. Designed to prevent the dangerous reverse flow of gases, this valve acts as a one-way street for your gas supply, ensuring that gases only travel towards your torch or application and never back into your regulator or supply line. This is crucial for preventing gas mixing, which can lead to equipment damage or safety hazards.

Featuring a standard 1/4" NPTF thread, this check valve is ready to install on compatible regulators, manifolds, or hard-piping systems. The rugged brass construction ensures it stands up to the demands of the shop environment, resisting rust and wear over time. Whether you are building a custom manifold or replacing a worn-out safety device, this check valve provides peace of mind by mechanically blocking backflow the moment it occurs.

Installation is straightforward, but always ensure you are installing the valve in the correct direction of flow, typically indicated on the valve body. By integrating this check valve into your system, you are adding an essential layer of protection for both your equipment and your personnel. Don't compromise on safety; ensure your gas lines are protected against reverse flow with reliable ESAB components.

FAQ

The check valve allows gas to flow in only one direction, preventing reverse flow which could contaminate gas supplies or create dangerous mixtures.

It features a 1/4" NPTF (National Pipe Taper Fuel) thread connection.

No. A check valve stops reverse gas flow, while a flash arrestor extinguishes a flame front. For complete protection, both are often recommended.

The valve body is constructed from durable brass.

Brass check valves are generally compatible with oxygen, but all components used in oxygen service must be kept free of oil and grease. Verify specific gas service ratings.

Check valves typically have an arrow stamped on the body indicating the direction of gas flow.

Specific cracking pressure data is not provided, but standard check valves open with minimal forward pressure.

Small check valves like this are typically non-repairable and should be replaced if they fail or leak.
