Key Takeaways

• Heavy-duty Victor 0381-1621 torch assembly
• Part of Victor’s ST900FC line with built-in Flash-Guard® check valves
• Compatible with standard Victor cutting attachments (CA1350, CA2460 series, etc.)
• Brass body, high-flow valves, rugged construction for shop or field use
• Solid choice for oxy-fuel cutting, gouging, and preheat/heating work

What the ST900FC Solves

1. Flashback protection

Built-in Flash-Guard® check valves help meet OSHA/ANSI recommendations for flashback prevention.

2. Consistent flow control

High-flow needle valves allow smoother oxygen/fuel metering than older economy torch bodies.

3. Shop-grade durability

Brass body and metal valve assemblies handle frequent usage, heat cycling, and impacts better than light-duty consumer torches.
