0781-1473 - Victor SR4K-677 High Pressure Inert Gas Piston Regulator

Heavy-Duty High Pressure Regulation for Inert Gases

When your operation demands reliable high-pressure gas control for inert gases, the Victor SR4K-677 High Pressure Regulator stands out as the professional's choice. Designed for the most demanding industrial applications, this regulator is a workhorse in the field of pressure vessel and dead-end testing. Whether you are working with Nitrogen, Argon, or Helium in high-pressure cylinders, the SR4K-677 delivers the consistent performance and safety you expect from the Victor brand. Its heavy-duty construction ensures that it can handle the daily wear and tear of a busy shop or job site without compromising on precision.

Safety and durability are at the core of the SR4K-677's design. The regulator features a solid machined brass body and a piston-style actuation system. Piston regulators are preferred in high-pressure scenarios because they are less prone to rupture than diaphragm models, providing an added layer of safety for the operator. With the ability to handle inlet pressures up to 7500 PSIG and deliver output pressures as high as 4500 PSIG, this tool is essential for high-stress testing environments. The inclusion of a Delrin cap bushing makes adjusting the pressure smooth and controlled, allowing for fine-tuning without the jerky movement often found in lesser regulators.

The Victor SR4K-677 is ready to integrate into your high-pressure system immediately. It comes equipped with a CGA 677 inlet connection, the standard for high-pressure inert gas cylinders, ensuring compatibility and safety compliance. The outlet is fitted with a high-quality 1/4-inch Swagelok fitting, providing a secure, leak-proof connection to your testing equipment or manifold. Large, easy-to-read 2.5-inch brass gauges allow you to monitor your gas supply and delivery pressure at a glance. Invest in the Victor SR4K-677 for a regulator that combines rugged durability with the high-pressure capability required for specialized industrial testing.
