The AIR-O-CRIMP™ fitting system has been developed for applications in which
hose end fittings must be attached at point of use in difficult applications such as Buses,Ambulances, RV’s, and Limos.
 
There is no need for a conventional crimping
tool in order to achieve a reliable connection of the fitting and hose.
