OVERVIEW

Reliable High-Pressure Oxygen Control with Victor SR4G-540

When your work demands high-pressure oxygen delivery for testing and specialized industrial applications, the Victor SR4G-540 (0781-1425) stands out as the professional's choice. Built by Victor, a leader in gas control equipment, this heavy-duty regulator is designed to handle the tough jobs that standard welding regulators can't touch. With a delivery pressure range of 100 to 1500 PSIG, it is perfectly suited for pressure vessel testing, dead-end testing, and other high-pressure oxygen requirements where accuracy and safety are non-negotiable.

The SR4G-540 is built like a tank, featuring a solid machined brass body and a piston-style actuation system. Piston regulators are preferred in high-pressure environments because they eliminate the risk of diaphragm rupture, offering a rugged solution for heavy industrial use. The regulator connects easily to standard oxygen cylinders via a CGA 540 inlet and is rated for a maximum inlet pressure of 3000 PSIG. For the outlet, it comes ready with a 1/4" Swagelok connection and stainless steel tube fitting, ensuring you have a secure, high-integrity connection point for your testing lines.

Ease of use is built into every detail. The Delrin cap bushing ensures that adjusting the pressure is smooth and consistent, preventing the jerky movement found in lesser regulators. The large, easy-to-read 2.5-inch brass gauges let you monitor your levels at a glance, keeping you informed and in control. Additionally, the integrated sintered bronze filter protects the internal mechanics from dirt and scale, ensuring your regulator performs flawlessly over time. Whether you are in the shop or out in the field, trust the Victor SR4G-540 to deliver the power and precision you need to get the job done right.

FAQ

The Victor SR4G-540 regulator has a delivery pressure range of 100 to 1500 PSIG.

It features a CGA 540 inlet connection, which is the standard for industrial oxygen cylinders.

This is a piston-type regulator, designed for high-pressure applications where durability is critical.

The regulator is rated for a maximum inlet pressure of 3000 PSIG.

The outlet is a 1/4" Swagelok connection equipped with a 1/4" stainless steel tube fitting.

While it controls oxygen, the delivery pressure (up to 1500 PSIG) is typically too high for standard oxy-fuel welding torches. It is designed primarily for testing applications.

Yes, it features an external adjustable relief valve for added safety.

The seat assembly is a cartridge type made with PCTFE, chosen for its high-pressure sealing capabilities.
