GTT Phantom: the two-stage, 22-jet Triple Mix torch for medium boro and pipes

The GTT Phantom is Glass Torch Technologies’ first real step into multi-stage power, a two-stage, 22-jet Triple Mix torch that takes the Lynx 7-jet center fire and wraps a 15-jet outer ring around it. That gives you two flames in one torch: a fine, controllable center for detail, and a second stage of heat for soaking medium boro, pipes, and functional work. It’s the model where GTT’s “center fire” idea becomes obvious, you’re running a Lynx with more fire stacked around it.

What the two-stage Triple Mix flame gives you

Triple Mix is GTT’s surface-mix technology: fuel and oxygen meet at the face of the torch, keeping the mixing chamber cool and producing a clean, penetrating flame that drives heat into the core of thicker glass. The Phantom’s second stage lets you go from a fine center flame up to a broader, hotter one as the work demands. For the underlying tech see GTT Triple Mix technology and surface mix vs premix torches; to understand why a penetrating flame suits functional boro, read soaking vs penetrating flame.

Who the Phantom is for

The Phantom suits intermediate-to-advanced makers working pipes, functional pieces, and medium boro who want a single torch that covers detail and soaking heat. It’s more torch than a beginner needs, and it stops short of the largest boro and heavy production the Mirage and bigger GTTs are built for.

Bench or hand torch

The Phantom is primarily a bench torch, but GTT also offers a Phantom hand torch with a thumb on/off switch for the outer flame, so you can run the fine center alone and bring in the second stage at the press of a thumb for off-bench, assembly, or larger work. If you’re deciding between formats, see bench vs hand torch.

Glass, fuel, and oxygen

The Phantom burns propane or natural gas with oxygen and runs both soft glass and boro. As a two-stage torch it’s hungrier than a single-stage burner, so plan your oxygen around running both stages, a single small concentrator may struggle to feed it fully. Our catalog carries a ~16.5 LPM reference converted from GTT’s flow table for the largest usable flame; size your supply to the flame you actually run and confirm with GTT. Start with how many LPM does my torch need.

Where it sits in the GTT lineup

The Phantom is the entry point to GTT’s multi-stage bench torches. Below it, the single-stage Lynx and Bobcat cover detail and versatile small-to-medium work; above it, the Mirage adds a second outer ring (40 jets) for large boro and production. The Phantom’s 15-jet ring also shows up as the middle stage inside GTT’s three-stage torches, so the flame behavior you learn here scales upward.

Before you buy

Budget for the whole system, not just the torch: oxygen sized for two stages, the correct propane or natural-gas regulator, flashback protection matched to your torch and gas supply, didymium or boro-rated eyewear matched to your glass, and ventilation. New to plumbing a torch? Start with the fittings, hoses & connectors guide and the glass torch safety setup guide.

Editor’s note: spec details reflect GTT’s own materials. The catalog’s ~16.5 LPM oxygen figure is converted from GTT’s flow table for the largest usable flame (a ceiling, not a minimum), and current configuration details should be confirmed with GTT before purchasing.
