0781-1453 - Victor SR4J-677 High Pressure Inert Gas Piston Regulator 3000 PSIG

Heavy-Duty High Pressure Control with Victor SR4J-677

When your work demands precision under extreme pressure, the Victor SR4J-677 High Pressure Inert Gas Regulator is the tool you can trust. Engineered by Victor, a leader in gas control equipment, this regulator is designed to handle the toughest jobs in the industry. Unlike standard regulators that use rubber diaphragms, the SR4J-677 features a solid brass piston actuation system. This design choice makes it incredibly tough and reliable, perfect for applications like pressure vessel testing and dead-end testing where failure is not an option.

The build quality of the 0781-1453 model is immediately apparent. It features a fully machined brass body and housing cap that resists corrosion and physical damage. Adjusting the pressure is surprisingly smooth thanks to the integrated Delrin cap bushing, which reduces friction and allows you to dial in the exact pressure you need, all the way up to 3000 PSIG. With a massive maximum inlet pressure rating of 7500 PSIG, this regulator is ready for the highest pressure cylinders available on the market today.

Safety and longevity are built into every component. The regulator includes a sintered bronze inlet filter to keep contaminants out of the mechanism, extending the life of the unit. The cartridge-type seat assembly uses PCTFE material, selected specifically for its ability to maintain a seal under high pressure without degrading. The unit comes ready to work with a CGA 677 inlet connection for high-pressure inert gases and a professional-grade 1/4" Swagelok outlet for secure attachment to your testing equipment.

Don't compromise on safety or performance when dealing with high-pressure gases. The Victor SR4J-677 delivers the consistent power and control you need to get the job done right. Whether you are pressurizing systems for leak checks or running high-pressure pneumatic tools, this regulator is the heavy-duty solution for professional welders and industrial technicians.
