GTT Sidewinder Glass Torch

The GTT Sidewinder is Glass Torch Technologies’ versatile surface-mix torch, a two-stage, 22-jet burner with a 7-jet center fire (configured as a standard-mix Bobcat or a Triple Mix Lynx) and a 15-jet, fully surface-mixed outer fire. It’s built to bring a controllable surface-mix flame to assembly, spot heating, and off-bench boro work, and GTT offers it both as a hand torch with an on/off switch in the handle for the outer flame and as a 2-/4-stud bench setup. Few GTT torches are as flexible about how you mount and run them.

What the two-stage surface-mix flame gives you

The Sidewinder is a surface-mix design: fuel and oxygen meet at the face of the torch, keeping the mixing chamber cool and giving a clean, penetrating flame. Triple Mix, GTT’s patented mixing technology, enters only if the center fire is a Lynx; with a Bobcat center it is standard surface mix throughout, and the 15-jet outer is fully surface-mixed either way. The listed price is for the Lynx-center configuration. The two stages let you go from a pinpoint up to a wide soaking flame, with an optional on/off switch in the hand torch to change between them. For the underlying tech see GTT Triple Mix technology and surface mix vs premix torches; for why a penetrating flame suits boro, read soaking vs penetrating flame.

Hand torch or bench

The Sidewinder comes as a 2- or 4-stud bench torch and as a hand torch, each with a 7-jet Lynx or Bobcat center fire inside a 15-jet outer fire. GTT sells six versions: the Lynx-center bench torch at $1,125, a Bobcat-center bench torch, and hand torches with a Lynx or Bobcat center, each with or without an on/off switch. The version picker at the top of 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.

For the Lynx-center bench torch, GTT gives a flame from a pinpoint up to 2 1/2 inches wide by 30 inches, solid borosilicate up to 3 inches, and melting through 3/4 inch rod in 45 seconds; its hand-torch page rates the Lynx-center hand torch for solid borosilicate up to 2.5 inches and for soft glass, boro and quartz. The bench instruction sheet sets tank fuel at 5 to 10 psi, natural gas at a minimum of 1/2 psi and tank oxygen at 10 to 40 psi, wider than the Flow Rate Chart row. The bench torch uses B fittings; custom color adds $30 (a hand torch $125). GTT gives no delivery date and notes that material availability can delay torches. If you’re deciding between formats, see bench vs hand torch.

Who the Sidewinder is for

It suits intermediate-to-advanced makers who need a mobile, controllable flame for assembly, spot heating, and boro rather than a single fixed detail burner. The wide flame range, a tiny pinpoint up to 2.5in x 30in for solid boro to 3in, is what lets one torch cover both fine and large hand work.

Glass, fuel, and oxygen

The Sidewinder burns propane or natural gas with oxygen, and GTT says its flame suits soft glass and borosilicate alike. GTT’s Flow Rate Chart, measured on propane at the largest usable flame, lists its fuel at 1/4 to 5 psi and oxygen at 5 to 15 psi; that 1/4 psi floor is about what an unboosted household natural gas line delivers, and GTT torches on natural gas covers the roughly 2.5 times larger volume natural gas burns and when a booster comes in. On the oxygen side, GTT says it runs great on two or three 8 LPM concentrators, and our catalog carries a ~15 LPM reference converted from GTT’s flow table for the largest usable flame; plan a multi-concentrator or tanked-oxygen supply and confirm with GTT. To size it to your work, see how many LPM does my torch need and oxygen concentrator vs tanks.

Where it sits in the GTT lineup

The Sidewinder is GTT’s mid-size hand torch / convertible, a surface-mix assembly torch sitting below the flagship Delta Elite hand torch. It shares its 7-jet center with the Lynx and Bobcat and its 15-jet outer ring with the Phantom, so the flame behavior is familiar across the line.

Before you buy

Budget for the whole system, not just the torch: a multi-concentrator or tanked oxygen supply, 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 price is GTT’s listed price for the 2-/4-stud bench configuration with Lynx center fire, and the oxygen figure is converted from GTT’s flow table for the largest usable flame; confirm your exact configuration and current pricing with GTT before purchasing.
