GTT Phantom Glass Torch

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 a 4-stud bench torch first, a 7-jet Lynx center inside a 15-jet outer ring, and GTT also builds it as a hand torch. GTT sells five versions: the 4-stud bench torch at $1,425, a compressed-air bench version, a bench torch with a variable switch, and a hand torch with or without an on/off switch. The version picker above the Specs section lists each one with GTT’s own name, its price as GTT’s pages showed it on 2026-10-06, and what GTT’s listing says about it; prices change, so confirm with GTT.

GTT’s instruction sheet for the Delta, Mirage and Phantom describes six valves on the bench torch (red fuel, green main oxygen and blue secondary oxygen for each stage), an optional foot pedal for the outer fire, and minimum settings of 5 psi fuel and 10 psi oxygen that give reduced results. For oxygen, GTT describes running the center fire on a concentrator and the outer fire on tanked oxygen. The bench torch ships with hoses (1 foot of 3/16 inch hose on each stud), screened adapters for 1/4 inch ID grade T hose, the base, instructions and a cleaning kit; GTT’s store listing also names a DVD. Custom color adds $150, and GTT lists a $200 rack-and-pinion upgrade kit that fits the Phantom 2 and 4 stud; what the kit contains, and how GTT’s bases are secured, is in our GTT cleaning and mounting guide. GTT gives no delivery date and notes that material availability can delay torches. 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. GTT’s Flow Rate Chart, measured on propane at the largest usable flame, lists it at 10 psi fuel and 35 psi oxygen, and GTT’s instruction sheet for the Delta, Mirage and Phantom gives the same two settings; GTT notes natural gas burns roughly 2.5 times the propane volume, and GTT torches on natural gas covers house lines. 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, and GTT Phantom oxygen requirements works through the LPM and PSI. 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. On the torch itself, GTT’s servicing page states a one-year warranty against factory defects that does not cover damage from improper use, misuse, or neglected maintenance; if you’re buying used, work through the used GTT torch checklist.

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.
