GTT Delta Elite: the 57-jet Triple Mix torch for large work, bench or hand

The GTT Delta Elite is Glass Torch Technologies’ big-flame specialist, a powerful two-stage, 57-jet Triple Mix burner built around the Lynx center fire with three rings (50 outer jets) stacked around it. The standard model on GTT’s product page is a four-stud bench torch at GTT’s listed price; GTT also sells a separate Delta Elite hand-torch version with its own controls and pricing, which is how many makers know the name: serious surface-mix heat brought to large assembly and off-mandrel work. 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.

Bench torch or hand torch

The Delta Elite comes both ways, and the two versions are distinct products on GTT’s site. The standard four-stud bench model fixes all that output at the bench. The hand-torch version is held and maneuvered, 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. Confirm which version, and which controls, you are pricing before you order. If you’re weighing the formats, 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 torch, its oxygen demand is substantial, realistically tanked oxygen or multiple concentrators rather than a single small unit. Our catalog carries a ~30 LPM reference converted from GTT’s flow table for the largest usable flame; 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 sits at the top of GTT’s two-stage range, and its hand-torch version is the off-bench counterpart to the 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 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 protection matched to your torch and gas supply, didymium or boro-rated eyewear matched to your glass, 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. The catalog price is GTT’s listed price for the standard four-stud bench configuration, and the oxygen figure is converted from GTT’s flow table for the largest usable flame; the hand-torch version is priced separately, so confirm your exact configuration with GTT before purchasing.
