The VALUE COLLECTION 2521682521 is a 10-piece ARO-interchange pneumatic coupling plug set designed for use in compressed air systems. Each piece in the set is a female connector with a 1/4 inch body size and 1/4 NPT thread, built from steel for durability in shop and industrial environments. The set is rated to 215 psi, making it suitable for standard shop air lines and pneumatic tool connections. Licensed HVAC techs, plumbers, and general trade professionals keep sets like this on hand for connecting and disconnecting air hoses and pneumatic tools quickly and without tools.
This coupling plug set is suited for compressed air distribution in residential and light commercial shop environments, maintenance facilities, and service vans. The ARO interchange type means these connectors are compatible with ARO-style pneumatic fittings and couplers commonly found on air compressors, blow guns, impact wrenches, and other pneumatic tools. The 10-piece count makes this set practical for outfitting multiple drop lines or service points at once.
Designed as an OEM-style replacement and general-service fit for ARO-interchange pneumatic systems using 1/4 inch body, 1/4 NPT fittings in compressed air applications.
Installation is typically performed by HVAC technicians, plumbers, pipefitters, or general maintenance professionals. Depressurize and bleed the air line completely before connecting or disconnecting any pneumatic coupling. Inspect threads before installation and apply thread sealant appropriate for pneumatic service if required by the application. Follow all applicable shop safety and compressed air handling procedures.
