AR Series ARO 210 Standard Quick Couplings

AR Series ARO 210 Quick Couplings for Standardized Air Connections

AR Series ARO 210 quick couplings are designed for pneumatic systems that use the ARO 210 interchange profile. The series is also identified as compatible with Parker 50 Series and Orion 44510 couplings, allowing users to select matching plugs and sockets across compatible systems. This makes the range a practical option for equipment manufacturers, workshops, and industrial air-line maintenance.

Four-Ball Locking and Multiple Connection Styles

The AR20 model features a 1/4-inch body and a four-ball locking mechanism. Its maximum working pressure is 2.0 MPa, with a specified temperature range of -10°C to +70°C.

Available configurations include:

● Socket types: Female thread (SF), male thread (SM), standard hose barb (SH), and push-lock hose barb (SHL).

● Plug types: Female thread (PF), male thread (PM), standard hose barb (PH), and push-lock hose barb (PHL).

● Materials: Brass, carbon steel, and stainless steel SUS303/304 options are listed in the ordering code.

● Thread sizes: 1/4", 3/8", and 1/2" NPT options are identified in the product coding.

The standard construction uses carbon steel with zinc plating or brass, with brass internal components. NBR is the commonly used seal, while FKM and other sealing materials may be available for specific operating conditions.

Applications in Pneumatic Equipment

AR Series ARO 210 couplings are suitable for air compressors, pneumatic tools, workshop air lines, spray equipment, and other compressed-air applications. Their interchangeable profile helps simplify component replacement when the mating connection is correctly matched.

Installation and Selection

Choose the socket and plug according to the required thread or hose connection. Check the coupling profile, body size, seal material, and working pressure before installation. Secure threaded joints with a suitable seal and inspect for leakage after pressurization. Disconnect only after isolating the air supply and releasing residual pressure.
