Victor SR4F-680 High Pressure Inert Gas Piston Regulator | 50-750 PSIG

Heavy-Duty Victor SR4F-680 Piston Regulator

When your job demands high-pressure control for inert gases, the Victor SR4F-680 (0781-1410) delivers the performance and reliability professional welders and technicians trust. This isn't your standard light-duty regulator; it is a heavy-duty piston regulator built to handle the extreme conditions of industrial testing and high-pressure supply. Whether you are conducting pressure vessel testing or performing dead-end testing, this regulator provides the consistent flow and pressure stability you need to get the job done right.

The SR4F-680 is built tough with a solid machined brass body and housing cap. It utilizes a brass piston actuation system rather than a rubber diaphragm. Piston regulators are legendary for their durability, eliminating the risk of diaphragm rupture in high-pressure scenarios. This model is designed to handle inlet pressures up to a staggering 5500 PSIG, connecting securely to your supply via a CGA 680 inlet. It delivers a versatile pressure range of 50 to 750 PSIG, giving you the power to tackle high-pressure tasks that standard regulators simply cannot handle.

Ease of use hasn't been sacrificed for strength. The regulator features a Delrin cap bushing that ensures the adjustment knob turns smoothly, allowing you to dial in your exact pressure requirements without binding or jumping. The 2.5-inch brass gauges are clear and durable, letting you monitor your tank and line pressure at a glance. Inside, a sintered bronze filter acts as a first line of defense, catching dirt and debris before it can cause internal damage, extending the life of your equipment.

Safety and compatibility are key features of the Victor SR4F-680. It comes standard with an external adjustable relief valve, providing peace of mind during operation. The outlet is fitted with a 1/4" Swagelok connection and a stainless steel tube fitting, ensuring a high-integrity connection to your hoses or testing apparatus. If you work with high-pressure inert gases and need equipment that won't let you down, the Victor SR4F-680 is the heavy-duty solution you've been looking for.
