14779-4-10 - Miller Smith 10ft Kevlar Twin Brazing Hose A-B Fittings

Technical Overview of the Miller Smith 14779-4-10

The Miller Smith 14779-4-10 Kevlar Brazing Hose is a specialized gas distribution component designed for precision brazing applications where maneuverability and durability are paramount. Unlike standard rubber hoses, this assembly utilizes advanced Kevlar reinforcement, providing exceptional heat resistance while significantly reducing the overall weight of the line. This reduction in weight minimizes drag on the torch handle, allowing for finer control during delicate brazing operations.

Technically, this twin hose is configured with differential fittings to match specific equipment setups. The regulator end terminates in standard "B" size fittings (9/16"-18 thread), compatible with most industrial gas regulators. The torch end steps down to "A" size fittings (3/8"-24 thread), which are specifically required for the Smith AW1A torch handle. This configuration eliminates the need for additional adapters when using the AW1A system. The hose is rated for use with both Acetylene and Propane fuel gases, offering versatility in fuel choice depending on the thermal requirements of the brazing task.

It is important to note that this hose is engineered strictly for brazing flow rates. The internal diameter and material construction are optimized for the lower flow requirements of brazing tips and are not recommended for use with cutting attachments, which demand higher volume gas flow. The 10-foot length is ideal for bench work or localized station applications, ensuring excess hose does not become a tripping hazard or obstruction.
