Operate micro-soldering, jewelry casting repairs, and precision oxy-fuel brazing with maximum portability using authentic Miller® SMITH Preset Regulators. Engineered specifically for the genuine Smith® Little Torch™ system, these solid brass, compact regulators screw directly onto disposable 14.1 oz and 16 oz canisters, eliminating the bulk and weight of traditional 20 lb gas cylinders. Available in industry-standard color-coded variations—the Red #249-500B Fuel Gas Regulator (CGA-600) for Propane and MAPP®/MAP-Pro, and the Green #249-499B Oxygen Regulator (CGA-601)—both units deliver pre-calibrated, non-adjustable operating pressure (4–8 PSIG) to ensure consistent flame performance straight out of the box.
Key Features & Benefits
-
Factory Pre-Calibrated Plug-and-Play Output: Eliminates the complexity of manual dual-gauge adjustment. Internal diaphragm calibration maintains a safe, stable working output (typically 4–8 PSIG), reducing operational error and ensuring an even gas feed to the torch handle.
-
Extreme Benchtop & Field Portability: Directly threads onto commercially available 14.1 oz and 16 oz disposable canisters, enabling fully mobile soldering and brazing setups without bulky industrial tanks.
-
Seamless “B” Fitting Hose Integration:
-
#249-500B (Red/Fuel): Features standard CGA 023 “B” 9/16”‑18 LH (Left‑Hand / reverse thread) outlet connection.
-
#249-499B (Green/Oxygen): Features standard “B” 9/16”‑18 RH (Right‑Hand thread) outlet connection.
-
Connects directly to genuine Little Torch™ dual-hose assemblies without additional step-down adapters.
-
-
Solid Brass Construction with Anodized Knurled Knobs: Precision-machined solid brass regulator bodies resist wear and corrosion, while knurled anodized control knobs provide smooth on/off gas shutoff with clear directional laser engravings.
