Short answer: For most buyers the choice comes down to two things. Nortel gives you the most proven surface-mix workhorses: a lineup that runs from the classic Nortel Minor starter up to boro burners like the Red Max, with the Minor a long-standing studio workhorse. GTT brings the patented Triple Mix flame, which starts at the Lynx and runs up the line, and its smallest models are charted to run on very low fuel pressure. Prices now overlap closely: at Nortel’s current US-dollar prices GTT’s Bobcat undercuts the Minor, while Nortel’s Major undercuts the Lynx. Pick Nortel for proven reliability and more jets per burner, and GTT for the Triple Mix flame ceiling (both brands run propane or natural gas with oxygen). This guide is about choosing between the brands, not re-listing every model; for the full ranges see the model-by-model GTT lineup and Nortel lineup guides.
What the two brands actually share
Before the differences, the common ground, because it is larger than most comparisons admit. Every GTT bench torch, and every classic Nortel bench burner from the Minor to the Rocket, is surface mix (Nortel’s newer Arrow and Hydra combine surface mix and premix, in its own description): fuel and oxygen stay separate until they meet at or just past the torch face, which gives a calmer, more forgiving flame than a premix burner. Both brands run propane or natural gas with oxygen, from bottled tanks or an oxygen concentrator. Both build durable metal-bodied torches with fine needle valves that a beginner can grow into and a professional can rely on for years. If you put a Nortel Minor next to a GTT Bobcat, you are looking at two 7-jet, single-stage, surface-mix bench torches that do very similar work.
The real divergence is GTT’s Triple Mix. Where a standard surface-mix torch surrounds the fuel with oxygen, Triple Mix also injects oxygen directly down the fuel stream, which GTT frames as a more complete burn. GTT gives you two independently controllable oxygen streams (the green and blue valves) so you can widen the flame range and adjust chemistry without swapping tips. That is the feature GTT’s Triple Mix models charge for, and it is worth understanding before you decide it matters to you. Our Triple Mix explainer goes deeper, and the surface mix vs premix guide covers the broader mixing question.
One thing to keep straight: Triple Mix is not GTT’s whole line. The entry Bobcat and the Cricket are standard surface mix. Triple Mix begins at the Lynx, GTT’s first Triple Mix torch, and continues upward. So a shopper cross-shopping GTT’s cheapest torch against a Nortel is not actually comparing Triple Mix at all.
Entry bench: Minor, Mega Minor, and the Bobcat
This is the tier where the two brands sit closest. The Nortel Minor is a surface-mix, 7-port bench torch with a stainless front end and precision needle valves, and Nortel names it for beads, small sculpture and marbles up to 3 inches, primarily in soft glass. At roughly $325 on Nortel’s own US-dollar listing it is one of the most common “I learned on this” torches in soft-glass beadmaking.
Step up to the Mega Minor at about $349 and you get the same 7-port surface-mix design tuned to use oxygen more efficiently for a larger, hotter flame, which works soft glass faster and reaches into small-scale boro sculpture.
GTT’s entry answer is the Bobcat at about $275 (reference), a single-stage surface-mix torch in the same entry band. At Nortel’s current US-dollar prices it costs about $50 less than the Minor and about $75 less than the Mega Minor, and it is popular partly for running well on a single modest oxygen concentrator. At this level the decision is genuinely close, so it gets its own head to head in Bobcat vs Minor. The short read: the Minor wins on used-market availability and its long studio track record, while the Bobcat wins on new price and is the pick if you want to stay in the GTT family as you climb.
The mid tier most buyers actually weigh
This is the tier where the brand question gets interesting, because it is where GTT’s Triple Mix first appears and where the two brands’ jet counts differ most.
On the GTT side, the Lynx at about $525 (reference) is the entry point to Triple Mix: a 7-jet, single-stage surface-mix bench torch. Above it the Cheetah at roughly $645 (reference) adds ports (a 3-port center fire inside a 10-port outer ring, 13 total) for a bigger flame envelope.
On the Nortel side, similar money buys noticeably more jets. The Major (about $492, our street estimate) is a 64-jet, two-stage surface-mix bench torch. The Red Max (about $894 with a Minor top, on Nortel’s own US-dollar listing) is a two-stage burner: a lower head Nortel labels 45-port, with a Minor, Mega Minor or premix top above it, running propane or natural gas with oxygen. If your priority is the most jets for the money, the Major is hard to beat; the Red Max now prices above the Cheetah and earns its place on versatility rather than price.
So the honest trade in this band is: more jets from Nortel (and a lower price on the Major), versus the Triple Mix flame and its independent oxygen control from GTT. If you work boro and want a flame whose chemistry you can tune without changing tips, the Lynx justifies its premium. If you want the most jets and are happy with a standard surface-mix flame, the Major or Red Max deliver. We compare the two most cross-shopped models directly in Lynx vs Red Max.
Editor’s note: Nortel labels the Red Max a 45-jet burner while describing port rings of 16 and 27, which sum to 43. We report Nortel’s own 45 label and flag the discrepancy rather than invent a center port. Treat published jet counts across both brands as maker figures, and confirm the current spec with the maker before you buy.
Production and the boro flame ceiling
At the top, the brands stop overlapping and start defining different ceilings. GTT’s production and large-boro tier climbs from the Phantom (about $1,425 reference, 22 jets, two stage) to the Mirage (about $1,975 reference, 40 jets, two stage) to the Delta Elite (about $2,575 reference for the standard four-stud bench, 57 jets; a hand-torch version is priced separately). These are Triple Mix torches built to push large borosilicate and sustain production work, and their prices reflect it.
Nortel’s classic upper bench burner is the Rocket, a two-stage, boro-focused surface-mix burner at about $1,521 on Nortel’s own US-dollar listing, a little above the Phantom, and the Red Max remains a capable large-flame option under a thousand dollars. Nortel can absolutely melt serious boro; what it does not offer is a Triple Mix flame at the very top of the range. If your work depends on the biggest and most tunable flame in either catalog (GTT’s line runs on past the Delta Elite to the Kobuki, Delta Mag, Cobra and Viper), that ceiling is GTT’s. If you want a big, proven surface-mix flame and do not need Triple Mix, that is Nortel’s argument.
Fuel and pressure: what your supply can feed
GTT’s second differentiator, alongside Triple Mix, is low fuel pressure. GTT torches are designed to work at fuel pressures far below what many burners need, which is the basis of the “runs on household natural gas” reputation. That reputation is per model, though. GTT’s flow rate chart starts the Cricket, Bobcat, Scorpion and Sidewinder rows at 1/4 psi of fuel, while the Lynx row reads 5 to 8 psi at its largest usable flame, and GTT’s Lynx instruction sheet sets the propane regulator to the same 5 to 8 psi. Standard unregulated household natural gas is roughly 1/4 psi, which the smallest GTT models are built for and the Lynx may not be at full flame. So GTT’s fuel flexibility is real, but “plug it into the house gas line” is a question to settle with GTT for the model you want. Our natural gas conversion guide covers what that involves.
Nortel is equally happy on propane or natural gas with oxygen, but its current product pages publish no pressure settings; the one Nortel figure we found is the Rocket product sheet’s 2 to 6 psi fuel and 7 to 15 psi oxygen, so ask Nortel for the exact model you are buying. Neither brand is locked to one fuel, and both depend far more on your oxygen supply than on the torch itself: a bigger torch of either brand that starves for oxygen underperforms a modest one that is well fed.
Whichever brand you choose, the manufacturer’s manual is the authority on pressures and setup, and it overrides any figure here. Fit the flashback protection your torch and gas supply call for rather than a one-size rule; the flashback arrestors guide explains why placement and device type depend on your specific setup.
Price at a glance
Catalog reference prices for the anchor models most buyers weigh. Figures come from the makers’ own pages where we have them, are of mixed capture dates, and several upper models are “from” starting prices. Nortel’s are its own US-dollar prices, converted from Canadian dollars and read 2026-10-17, except the Major, which is our street estimate. Confirm the current number with GTT or Nortel before you buy.
| Tier | GTT | Nortel |
|---|---|---|
| Entry bench | Bobcat ~$275 (surface, 7 jets) | Minor ~$325, Mega Minor ~$349 (surface, 7 jets) |
| Mid | Lynx ~$525 (Triple Mix, 7 jets), Cheetah ~$645 (13 jets) | Major ~$492 (64 jets), Red Max ~$894 (45 jets) |
| Upper / production | Phantom ~$1,425, Mirage ~$1,975, Delta Elite ~$2,575 | Rocket ~$1,521 |
The pattern is about jets more than price: Nortel’s mid-tier burners carry far more jets, while at Nortel’s current US-dollar prices GTT is the cheaper entry and the Phantom sits just under the Rocket. What GTT’s Triple Mix models charge for is the Triple Mix flame and its independent oxygen control. Neither is “better” in the abstract; they optimize for different things.
How to choose
- Soft glass and beads, the proven starter: Nortel Minor. Its used-market availability and studio track record are hard to match, though the GTT Bobcat is now about $50 cheaper new.
- Lowest new price, or one small concentrator: the GTT Bobcat, and a natural start if you want to build into the Triple Mix family later. The Nortel Mega Minor is the larger-flame Nortel alternative.
- Most jets for boro: Nortel Major or Red Max. Far more jets than the GTT mid tier, standard surface-mix flame; the Major also prices below the Lynx.
- You want the Triple Mix flame: start at the GTT Lynx and go up. This is the one thing Nortel does not offer, and it is the whole reason to pay GTT’s premium.
- Household natural gas is your fuel: GTT’s low-pressure design leans your way, but plan for adequate regulated pressure; do not assume unregulated house gas is enough.
- Top-end production and the biggest boro flame: GTT Phantom, Mirage, or Delta Elite. Nortel’s Rocket is the surface-mix alternative if you do not need that ceiling.
