GTT Delta Elite: the 57-jet Triple Mix hand torch for assembly and large work

The GTT Delta Elite is Glass Torch Technologies’ big-flame hand torch — a powerful two-stage, 57-jet Triple Mix burner built around the Lynx center fire with three rings (50 outer jets) stacked around it. Where most GTT torches live on the bench, the Delta Elite is designed to bring serious surface-mix heat to the work: large assembly, off-mandrel sculpting, and heavy borosilicate done in the hand rather than at a fixed burner. An optional variable switch lets you modulate the flame as you work.

What the Triple Mix flame gives you

Triple Mix is GTT’s surface-mix technology: fuel and oxygen meet at the face of the torch, which keeps the mixing chamber cool and produces a clean, penetrating flame that drives heat into the core of thick glass. With a Lynx center and three outer rings, the Delta Elite spans a wide range — from a finer center flame up to a broad, powerful one. For the underlying tech see GTT Triple Mix technology and surface mix vs premix torches; for why a penetrating flame suits thick boro, read soaking vs penetrating flame.

Why a hand torch

A hand torch is held and maneuvered rather than mounted, which is exactly what you want for assembly, off-mandrel work, and spot heating on large pieces — bringing a precise, powerful flame to a join instead of wrestling the work in front of a bench burner. The Delta Elite is the high-output end of that idea. If you’re weighing a hand torch against a bench burner, see bench vs hand torch.

Who the Delta Elite is for

This is an advanced tool for large work and assembly in borosilicate. It rewards a maker who already knows how they want to work and needs a powerful, mobile flame to do it. It is emphatically not a first torch, and the oxygen appetite and price reflect that.

Glass, fuel, and oxygen

The Delta Elite burns propane or natural gas with oxygen and is built for boro. As a high-output, multi-ring hand torch, its oxygen demand is substantial — realistically tanked oxygen or multiple concentrators rather than a single small unit. GTT doesn’t publish the Delta Elite’s exact LPM, so size your oxygen to your work and confirm with GTT. Start with how many LPM does my torch need.

Where it sits in the GTT lineup

The Delta Elite is GTT’s flagship hand torch, the off-bench counterpart to its big bench burners. It shares the Lynx center with the Phantom and Mirage, so the flame behavior is familiar even though the form factor and power are not. GTT’s smaller Sidewinder covers lighter hand-torch assembly and spot heating; the Delta Elite is the one you reach for when the work is large.

Before you buy

Budget for the whole system, not just the torch: an oxygen supply sized to a high-output torch, the correct propane or natural-gas regulator, flashback arrestors on both lines, didymium eyewear, and serious ventilation. New to plumbing a torch this size? Start with the fittings, hoses & connectors guide and the glass torch safety setup guide.

Editor’s note: spec details reflect GTT’s own materials. GTT doesn’t publish the Delta Elite’s exact oxygen flow (LPM) or current pricing, so confirm those specifics with GTT before purchasing.
