GTT Samurai Glass Torch

The GTT Samurai is GTT’s three-stage torch built on a Mirage core. GTT sells it as the Samurai with Mirage Inner: a 7-jet Lynx center and a 33-jet Mirage middle, 40 jets in the two inner fires, which is the standalone Mirage’s own jet count, wrapped in a 32-jet outer fire for 72 jets in all. Compared with its sibling the Ninja, which has the same total, the Samurai keeps more of its jets in the inner fires and fewer in the outer one. GTT ranks it between the Kobuki and the Delta Mag and calls the body compact and easy to work behind. If you go looking on GTT’s site, the page address spells it “samauri”.

Why the Mirage core matters

Split the Samurai’s 72 jets by stage and the design is plain: 40 in the center and middle fires, 32 in the outer fire, so a little over half the torch works before the third fire is lit. The Ninja inverts that, with 22 inner jets and 50 outer. GTT pitches the Samurai at workers who like the Mirage-size flame and want a third fire for production, the counterpart of the Ninja’s Phantom-size pitch. We publish no flame-size or temperature figures for either, because GTT publishes none; our Ninja vs Samurai comparison covers the trade, Phantom vs Mirage compares the two cores on their own, and Mirage vs Delta Elite shows where the Mirage line steps up.

Each of the three fires uses Triple Mix, GTT’s patented surface-mix scheme. GTT describes it as oxygen surrounding the fuel with more oxygen injected down the fuel stream through a separately controlled valve; GTT Triple Mix technology explains it.

Running it from GTT’s sheet

The Samurai shares its instruction sheet with the Ninja, and the sheet is specific. Fuel is set at 15 psi and oxygen at 50 psi. There are nine valves, three per fire (red fuel, green main oxygen, blue secondary oxygen); with the torch viewed from behind, the furthest set controls the center, the next set the middle and the nearest set the outer fire. Light the center from red to a yellow flame of about 7 inches, then green, then blue. The outer fires start at about 8 inches of yellow and take green before blue, and the third fire is only lit once both inner fires are going, so the Samurai’s 32-jet outer fire always runs around a burning Mirage core. Red and blue alone is a center-fire mode, and on candles shorter than 3/8 inch GTT wants some blue on to keep carbon out of the injectors; GTT’s wider care advice is gathered in our GTT cleaning and mounting guide. For house gas, GTT’s chart notes put natural gas at about 2.5 times the propane volume; GTT torches on natural gas has the detail.

The three versions, and one conflict

GTT’s standard Samurai with Mirage Inner is $4,000. GTT also lists a Samurai with Compressed Air Option and a Snub Nose Samurai with GTT’s new variable switch, both in the version picker at the top of the Specs section with their prices as read on 2026-10-06. The compressed-air listing is the one to check before you order: its description copies the Ninja’s name and the Phantom-middle layout, which contradicts GTT’s own Samurai page, so we do not state its jet count and you should ask GTT which torch it describes. For air, GTT specifies clean, dry air regulated to 60 psi or lower, and says the air controls flame temperature “while maintaining flame chemistry and flame type” (see GTT compressed air and 4-Way Mix). The Snub Nose listing names three stages and the switch and nothing more.

In the box, GTT lists 2 feet of 3/16 inch hose, screened adapters for 1/4 inch ID grade T hose, the base, instructions and a cleaning kit, with a DVD named on the store listing. The base is powder-coated with mounting holes and carries six studs with rack-and-pinion adjustment. A custom color is $200 extra, and GTT commits to no delivery date, noting that material availability can delay a torch.

Supply, glass and fit

No Samurai row appears on GTT’s Flow Rate Chart and GTT gives no oxygen flow for it, so we carry no estimate. Plan for tanked oxygen or a concentrator bank once the outer fire is in use, settle the supply with GTT, and use how many LPM does my torch need as the starting point. The catalog records the Samurai on propane or natural gas, for soft glass and borosilicate, aimed at production, large boro and fast melt-ins, and at advanced workers.

Before you buy

The torch is only part of the bill. Add oxygen for three stages, the regulator for your fuel and an air source if you choose the air version, flashback protection matched to your torch and gas supply, eyewear rated for your glass and serious ventilation; the glass torch safety setup guide and the fittings, hoses and connectors guide walk through it. GTT’s servicing page gives a one-year warranty against factory defects, excluding damage from improper use, misuse or neglected maintenance. Buying secondhand? Use the used GTT torch checklist.

Editor’s note: the Samurai’s layout, settings and versions come from GTT’s own pages and instruction sheet as read on 2026-10-06, including the conflicting compressed-air listing. GTT publishes no oxygen flow for the Samurai; confirm the configuration and price with GTT before you buy.
