25316BA25 - 3/16" x 25' Twin Welding Hose, Grade R, B-Fitting to A-Fitting

Specialized Connection for Precision Welding Setups

The Dixon Twin Hose 3/16 B TO A-1 Fitted 25ft is a specialized gas delivery solution designed to bridge the gap between different standards of welding equipment. In the world of oxy-fuel welding and cutting, equipment connection sizes can vary based on the duty cycle and manufacturer of the torch and regulators. Standard industrial regulators typically utilize "B-size" (9/16"-18) outlets, while lighter-duty, precision torches—often used for jewelry making, HVAC repair, or light fabrication—may utilize smaller "A-size" (3/8"-24) inlets. This hose is pre-configured to connect these two distinct sizes directly, eliminating the need for bulky brass adapters that can add weight to the torch end and introduce potential leak points.

Durable Grade R Construction

Constructed to meet the demands of industrial environments, this twin hose is built with a Grade R rating. This designation indicates that the hose is specifically engineered for use with acetylene gas. The inner tube and outer cover are made from a durable rubber compound that resists abrasion, weathering, and ozone deterioration. The red line is designated for the fuel gas (acetylene), while the green line carries the oxygen, adhering to industry-standard color coding for safety and easy identification. The 3/16-inch inner diameter is perfectly sized for light-to-medium duty applications, ensuring adequate flow rates without the bulk and stiffness of larger hoses.

Convenience and Safety

Safety in welding operations is paramount, and the integrity of your gas delivery system is the first line of defense. This hose features factory-crimped ferrules that provide a superior seal compared to field-repair kits or worm-gear clamps. The 25-foot length offers a practical balance between reach and manageability, allowing the operator to move freely around the workpiece without excessive slack creating a tripping hazard. By integrating the size adaptation directly into the hose assembly, users enjoy a streamlined setup that is lighter, safer, and more efficient to deploy in the field or workshop.
