ARB Air Systems will supplement the line of air compressors by introducing complete vehicle - specific solutions for enthusiasts looking to equip their vehicles with compressors and accessories. The product range will include items such as air fittings, various lengths of stainless braided PTFE hose, and air chuck mounting solutions. Together, these will provide all the necessary components to fit a complete air compressor system to a 4wd, allowing a vehicle to be outfitted front to back with on - demand air. The ARB 90 - Degree Elbow Fitting is used to connect a NPT port (such as on an ARB CKM series compressor) to a 07402XX series hose where space is limited, and the hose would otherwise have to bend sharply.
