Victor 0781-1425 Single Stage Oxygen Regulator 3000 Psig

Product Description

The VICTOR 0781-1425 is a heavy-duty, high-capacity, single-stage piston regulator designed for high-pressure oxygen service. It features a machined brass body with housing cap and delivers outlet pressure in the range of 100 to 1500 psig, with a maximum inlet pressure of 3000 psig. The piston-type actuation uses a brass piston with a Delrin cap bushing for smooth, repeatable adjustment. A cartridge-type seat assembly with a PCTFE seat provides reliable shutoff and long service life. Two 2.5-inch brass gauges give clear pressure readings at both inlet and outlet. This regulator is sold as a single unit and is installed by qualified gas system technicians or welding supply professionals.

The VICTOR 0781-1425 is engineered for demanding high-pressure applications, particularly pressure vessel testing and dead-end testing scenarios where stable, precise delivery pressure is critical. The 540 CGA inlet connection with a bronze sintered filter protects internal components from particulate contamination. The outlet uses a 1/4-inch Swagelok connection with a 1/4-inch stainless tube fitting, making it well suited for controlled laboratory, industrial, and field testing environments where clean, consistent oxygen delivery is required.

Key Features

• Machined brass body and housing cap for durability in high-pressure oxygen service
• Piston-type actuation with Delrin cap bushing for smooth pressure adjustment
• Cartridge-type seat assembly with PCTFE seat for reliable sealing
• External adjustable relief valve for overpressure protection
• Bronze sintered inlet filter to protect regulator internals
• 1/4-inch Swagelok outlet connection with stainless tube fitting
• Dual 2.5-inch brass gauges for inlet and outlet pressure monitoring

Compatibility

Designed for use with oxygen gas supply cylinders equipped with a 540 CGA outlet. Intended for high-pressure oxygen delivery systems used in pressure vessel testing and dead-end testing applications.

Installation Notes

Installation should be performed by a qualified technician familiar with high-pressure oxygen systems and applicable compressed gas safety standards. Always fully close the cylinder valve and relieve all system pressure before connecting or disconnecting the regulator. Ensure all fittings, tubing, and downstream components are rated and cleaned for oxygen service before pressurizing. Inspect the sintered inlet filter and seat assembly periodically per the manufacturer service interval.
