How to Replace Pneumatic Fittings

Replacing pneumatic fittings on the end of a pneumatic air hose is necessary when the fitting jambs or wears out. The connection inside the fitting can wear out and stop closing the air flow when the tools are disconnected. The pneumatic fitting is designed to be used with an air compressor for quick connection to air tools. You can replace the fitting on the hose in just a few minutes with some basic tools.
