HOSACET3/16 - 3/16" Acetylene Hose 12ft with A-Fittings and Strain Guards

Technical Overview: 3/16" Acetylene Hose with "A" Fittings

This product is a specialized single-line gas hose designed specifically for the transport of Acetylene fuel gas in light-duty welding, brazing, and cutting applications. The hose features a 3/16-inch internal diameter (ID), which is narrower than standard industrial hoses, providing reduced weight and drag for the operator. This is particularly critical when utilizing precision torches where hand fatigue and maneuverability are concerns. The hose is color-coded red in accordance with industry safety standards for fuel gases, ensuring immediate visual identification and preventing dangerous cross-connections with oxygen lines.

The assembly comes pre-fitted with "A" size connections. It is vital to verify equipment compatibility, as "A" fittings utilize a 3/8"-24 thread pitch, distinct from the larger "B" size (9/16"-18) found on standard heavy-duty equipment. These fittings are Left-Hand (LH) threaded, indicated by the notched nut, to further ensure safety by preventing connection to non-fuel gas outlets. The crimped ferrules are robust and designed to withstand standard operating pressures for acetylene gas.

A key structural feature of this assembly is the inclusion of spring strain relief guards at both ends. These metal springs extend over the hose from the ferrule, distributing bending stress and preventing the hose from kinking or collapsing at the connection point—the most common area of failure in gas hoses. This addition maintains consistent gas flow and prolongs the service life of the assembly in dynamic workshop environments. The 12-foot length provides ample reach for bench-top applications or localized repairs without creating excessive slack that could become a tripping hazard.
