Coilhose Pneumatics 14X-1401-T2 Aro Coupling Plug Set 18pc

Product Description

The COILHOSE PNEUMATICS 14X-1401-T2 is an 18-piece ARO-style pneumatic coupling plug set designed for compressed air and pneumatic tool connections in shop, industrial, and field service environments. The set includes 12 male connectors and 6 female couplers, all sized at 1/4-inch body with 1/4 NPT thread connections. Constructed from brass and steel, these fittings deliver reliable sealing and durability under typical shop air pressures. The ARO interchange profile is one of the most widely used standards in North America, making this set a practical stocking solution for service vans, maintenance shops, and tool rooms.

This coupling set is suited for use in residential, commercial, and light industrial pneumatic systems wherever ARO-interchange fittings are the site standard. The 12 male connectors and 6 female couplers provide a balanced assortment for outfitting multiple tools and hoses from a single kit. Typical applications include air compressor hose connections, pneumatic hand tool hookups, and shop air distribution lines. The 1/4 NPT thread standard is compatible with the majority of pneumatic hoses, tools, and manifolds common in HVAC, plumbing, and general mechanical trades.

Key Features

Compatibility

Designed for use with ARO-interchange pneumatic systems using 1/4-inch body couplings and 1/4 NPT threaded hoses, tools, and fittings.

Installation Notes

Installation is typically performed by mechanics, HVAC technicians, or maintenance personnel working with compressed air systems. Depressurize and bleed the air line completely before removing or installing any coupling or connector. Apply thread sealant appropriate for pneumatic service to NPT threads to ensure a leak-free connection. Do not overtighten threaded fittings, as this can crack brass bodies or distort sealing surfaces.
