Value Collection 2321572531 Pneumatic Coupling Plug Set

Product Description

The VALUE COLLECTION 2321572531 is a five-piece ARO-style pneumatic coupling plug set designed for use in compressed air systems. Each set contains five female couplers with a 1/4-inch body size and 1/4 NPT thread connections. The couplers are rated to 215 psi and constructed from zinc for durability in shop and industrial environments. This set is a practical solution for technicians who need to outfit multiple air tool connections or service points in a single purchase. Licensed HVAC technicians, plumbers, and general maintenance professionals commonly use ARO-style quick-disconnect couplings for air-powered tools and pneumatic equipment.

This coupling plug set is suited for light industrial, commercial, and trade shop applications where ARO-interchange pneumatic fittings are standard. The 1/4 NPT thread is a widely used connection standard in compressed air distribution lines, making these couplers compatible with a broad range of air compressors, hoses, and pneumatic tool fittings. The set is particularly useful when equipping a new shop, staging multiple drop lines, or replacing worn couplers across a fleet of hose assemblies.

Compatibility

Designed as an ARO-interchange style replacement for 1/4-inch body, 1/4 NPT pneumatic female couplers used in standard compressed air distribution and pneumatic tool systems.

Installation Notes

Installation is typically performed by maintenance technicians or plumbers familiar with threaded pipe connections. Depressurize the air line completely before removing or installing any coupler. Apply thread sealant tape or compound to NPT threads in accordance with shop practices and applicable codes before tightening. Do not exceed the 215 psi rated working pressure of these fittings.
