Parker A2C Pneumatic Hose Coupling 1/4-18 Npt Aro

Product Description

The PARKER A2C is a pneumatic hose coupling nipple designed for quick-connect air and fluid line applications in industrial and trade environments. Machined from steel with a zinc chromate finish, this nipple features a 1/4-18 MNPT threaded connection and a 1/4 inch body diameter. It carries a maximum working pressure of 300 psi and operates across a temperature range of -40 to 250 degrees F. The A2C belongs to Parker's Series 50 and is sized for common shop-air and pneumatic tool lines. Installation is handled by maintenance technicians, pipefitters, and industrial mechanics working on compressed air distribution systems.

The A2C fits into pneumatic quick-disconnect setups that follow the ARO interchange standard, making it compatible with ARO-pattern couplers widely used across industrial facilities, automotive shops, and construction sites. The 1/4-18 NPT thread is the most common thread size found on air tools, compressors, and inline components, making this nipple a frequent service and replacement item. Its compact 1.62 inch overall length suits tight installations where clearance around the connection point is limited.

Installation Notes

Depressurize and lock out the compressed air system before removing or installing any pneumatic coupling component. Apply thread sealant appropriate for pneumatic service to the MNPT threads before installation. Use a wrench on the hex to tighten to a secure fit without over-driving the threads into the mating port. Verify system pressure does not exceed the 300 psi rated maximum after returning the line to service.
