RTC 13mm Hose Tail Plug (Industrial 1/2" Interchange)
High-Performance Industrial Air Fitting
The RTC 13mm Hose Tail Plug is designed for high-volume air delivery in heavy industrial environments. This plug features a 13mm (1/2") hose barb (tail), making it the ideal choice for assembly onto large-bore rubber or PVC air hoses used with 3/4" and 1" Impact wrenches, grinders, and air-hungry machinery.
As part of the Industrial 1/2" series, this plug provides a significantly larger internal bore than standard 1/4" fittings, eliminating the common bottleneck that prevents tools from reaching their full torque and power.
