Micro Inline Reg, Filter and Lube (Ideal for Airtools)

Pneumatic regulators, also known as pressure-reducing valves, are used in pneumatic systems to maintain the output air pressure. 

A pneumatic lubricator injects an aerosolised stream of oil into an air line to provide lubrication to the internal working parts of pneumatic tools, and to other devices such as actuating cylinders, valves, and motors.
