Value Collection 2321582531 Pneumatic Coupling Plug Set

Product Description

The VALUE COLLECTION 2321582531 is a five-piece ARO-style pneumatic coupling plug set designed for use in compressed air systems. Each piece is a male coupler with a 1/4-inch body size and 1/4 NPT thread connection, rated to 215 psi working pressure. The couplers are constructed from zinc, providing adequate corrosion resistance for typical shop and industrial air line applications. This set is sold as a quantity of five identical male plugs, making it a practical option for stocking multiple connection points or replacing worn couplers across a pneumatic circuit. Installation is straightforward and is typically handled by maintenance technicians, plumbers, or pneumatic system integrators.

This coupling plug set is suited for use in residential, commercial, and light industrial compressed air systems where ARO-interchange fittings are the standard. The 1/4-inch body and 1/4 NPT thread sizing fits common air hose assemblies, compressor outlets, and pneumatic tool connections. The 215 psi pressure rating covers the operating range of most shop compressors and portable air systems. Having five couplers in a single package supports initial installation or maintenance restocking on multi-drop air lines.

Key Features

• Five male couplers included per package for multi-point installations or restocking
• 1/4-inch body size with 1/4 NPT threaded connection
• 215 psi maximum working pressure rating
• Zinc construction for durability in standard shop air environments
• ARO-interchange style for broad compatibility with ARO-pattern pneumatic fittings

Compatibility

Designed as an OEM-style replacement or new-install fitting for compressed air systems using ARO-interchange pneumatic couplings with 1/4-inch body and 1/4 NPT thread connections.

Installation Notes

Pneumatic couplings of this type are installed by maintenance technicians or pipefitters working on compressed air distribution systems. Always depressurize and bleed down the air line before removing or installing any coupling or plug. Apply thread sealant appropriate for compressed air service to the NPT threads before assembly. Follow applicable shop safety practices and local codes when working on compressed air systems.
