249-500B - Smith Little Torch Preset Propane Regulator for Disposable Tanks

Precision Control for Micro-Joining Applications

The Smith Equipment 249-500B Preset Propane Regulator is an essential component for jewelers, hobbyists, and field technicians utilizing The Little Torch system. Engineered to provide a consistent and safe flow of fuel gas, this regulator is specifically calibrated for use with disposable propane cylinders, such as the standard 14.1 oz and 16 oz tanks commonly found in hardware and camping stores. By utilizing a preset delivery pressure mechanism, Smith Equipment ensures that the gas flow remains stable and optimized for the microscopic orifices found in Little Torch tips, preventing flame fluctuation that could compromise delicate soldering or brazing operations.

Unlike industrial regulators that require manual pressure adjustment, the 249-500B is designed for simplicity and reliability. The internal diaphragm is factory-set to deliver the correct pressure range (approximately 8-15 PSIG) required for the efficient operation of the torch. This feature not only simplifies the setup process but also enhances safety by preventing over-pressurization of the miniature hoses and torch handle. The regulator body is constructed from high-quality brass, ensuring durability and resistance to corrosion, which is a hallmark of the Smith Equipment manufacturing standard.

Connectivity is seamless with the 249-500B. The inlet is designed to screw directly onto the top of standard disposable cylinders (CGA 600 connection), creating a secure and leak-free seal. The outlet features a standard "B" size 9/16"-18 Left Hand thread, making it compatible with the standard fuel hoses supplied with most Little Torch kits. This compatibility ensures that users can easily replace an existing regulator or convert their setup for maximum portability without needing specialized adapters. Whether you are performing intricate gold repairs in a studio or brazing copper lines in the field, this regulator provides the consistent performance professionals demand.

For users who require mobility, this regulator transforms The Little Torch into a truly portable system. By eliminating the need for heavy, refillable 20lb propane tanks, artisans and technicians can transport their heating equipment with ease. The compact profile of the regulator adds minimal bulk to the cylinder, allowing the entire fuel source to be handled comfortably or placed in a small carrier. Backed by Smith's 1-year warranty, the 249-500B represents a reliable investment in precision gas control.
