OVERVIEW

Compact and Flexible Oxy-Acetylene Delivery

The PW316-12 Twin Oxy/Acetylene Hose is a specialized gas delivery solution designed for precision and portability. Measuring 12 feet in length, this hose assembly is specifically tailored for workstations, bench-top brazing, and portable welding rigs where excess hose length can become a safety hazard or logistical nuisance. The hose features a 3/16-inch internal diameter (ID), which provides a significant reduction in weight and an increase in flexibility compared to standard 1/4-inch hoses. This makes it an excellent choice for light-to-medium duty applications such as HVAC repair, jewelry manufacturing, and general maintenance where torch maneuverability is critical.

Standardized Compatibility

Engineered for seamless integration with existing equipment, the PW316-12 comes pre-fitted with industry-standard B-Size (9/16"-18) brass fittings. These fittings ensure compatibility with the vast majority of industrial oxygen and acetylene regulators and torch handles found in North America. The fittings are securely crimped with heavy-duty ferrules to withstand working pressures and prevent leaks. The hose utilizes a twin-line "Siamese" construction, keeping the oxygen and fuel lines bonded together to prevent tangling while allowing them to be separated at the ends for connection to equipment.

Safety and Identification

Safety is paramount in oxy-fuel operations. This hose assembly adheres to the standard color-coding system: Green for Oxygen and Red for Acetylene (fuel gas). This visual distinction aids operators in making correct connections quickly, reducing the risk of cross-connection. The outer cover is formulated to resist abrasion, incidental sparks, and ozone deterioration, ensuring a reliable service life in workshop environments. While designed primarily for acetylene, operators should always verify the hose grade rating printed on the jacket to ensure compatibility with alternative fuel gases if necessary.

FAQ

A 3/16" hose is lighter and more flexible, making it ideal for light-duty torches and precision work. A 1/4" hose allows for higher flow rates required for heavy-duty heating and cutting tips.

Yes, this hose comes with B-Size (9/16"-18) fittings, which are the industry standard for most regulators and torches in North America.

This hose is labeled for Oxy/Acetylene. Unless the hose jacket specifically states 'Grade T', it should be used with Acetylene only. Propane can deteriorate Grade R hoses over time.

The nut on the red (acetylene) hose is notched to indicate it has left-hand threads. This is a safety feature to prevent connecting the fuel hose to the oxygen supply.

12ft is considered a short hose, best for bench work or portable kits. For general shop use where you move around a vehicle or large assembly, a 25ft or 50ft hose is usually recommended.

You should inspect your hose for cuts, burns, cracks, or leaks before every use. Replace the hose immediately if any damage is found or if it fails a leak test.

No, this is the hose assembly only. Flashback arrestors are sold separately and are highly recommended for safety.

Standard welding hoses are typically rated for a maximum working pressure of 200 PSI, but you should always check the printing on the hose itself for the specific rating.
