Features

• Graf-Tite soft seats – Resilient Graf-Tite seat material protects tip seating areas from nicking to maintain positive seating. Requires less replacement than metal-to-metal seat designs. Compressible soft seats are practically indestructible and withstand extremely high temperatures, resulting in longer tip life.
• In-tip mix – Each tip is a precision engineered mixer for combining preheat oxygen and fuel gas to attain maximum efficiency. Adds resistance to flashback.
• Slip-in tip design just hand tighten After the first tightening with a wrench, only hand tightening is required to seat the tip, saving time when changing tips. Quick and easy tip changes encourage use of right tip for the job.
• Removable high-pressure seat – Allows cleaning from back of tip.
• Three-tube construction – Gases are kept separated, eliminating mixing tube burnout. Our thick-wall, high-capacity stainless steel tubes provide high gas flow and superior strength.
• Ease-on oxygen cutting valve – Allows smooth piercing and keyhole free starts and restarts.
• Triple o-ring seal – Provides positive gas seal, and allows rotation.
• Internal threads – Threads are protected from damage if the torch is dropped, eliminating costly torch repair, replacement or downtime.
• Double-tube handle – Tube-within-a-tube design provides strength while reducing weight. Internal tube is silver brazed for extra protection, strength and leak resistance.
• Adjustable valve resistance – Special PTFE packing provides a gas-tight seal while allowing the drag to be adjusted to the individual preference.
• Stainless steel ball-style valves – Corrosion-resistant balls and brass seating surfaces provide gall resistance and positive, chatter-free seating.
• Replaceable hose connections – Hose connections are easily replaced if damaged.
