Victor 0781-9431 Single Stage Acetylene Regulator

Product Description

The VICTOR 0781-9431 is a heavy-duty, single-stage acetylene regulator designed for reliable gas pressure regulation in daily welding and cutting operations. Part of the G350 series, it delivers consistent downstream pressure control for acetylene supply lines. The regulator features high-contrast 2.5-inch gauges for easy pressure reading in shop or field conditions, and a high-strength alloy bonnet that provides durability under repeated use. It is installed by welding professionals, HVAC technicians, and pipefitters working with oxy-fuel systems.

This regulator is suited for standard acetylene service in both shop and jobsite environments. It handles routine gas regulation tasks without compromise in build quality. The single-stage design steps down cylinder pressure to working pressure in one stage, making it a straightforward choice for typical oxy-acetylene torch setups used in welding, brazing, and cutting applications.

Key Features

• Single-stage pressure regulation for acetylene gas service
• Heavy-duty construction with high-strength alloy bonnet
• High-contrast 2.5-inch gauges for clear pressure readings
• Compact form factor suited for shop and field use

Compatibility

Designed as an OEM-style replacement or direct-service regulator for acetylene cylinder and manifold systems using standard acetylene inlet connections.

Installation Notes

Installation should be performed by a qualified welding professional or licensed pipefitter familiar with compressed gas systems. Always close the cylinder valve and bleed the regulator before connecting or disconnecting. Inspect inlet threads and seat condition prior to installation and never use oil or grease on regulator fittings. Follow CGA and applicable local codes for compressed gas handling and storage.
