Lock-on hose system is easy to use and does not require clamps or special tools to use.  (We use a dab of dish soap to assist in pushing the hose over the barbed fittings...works like a charm)  The water feed hose and tube can easily be cut to the required lengths using a pvc cutter.   Most of our pumps utilize the 3/8" hose, we also carry 1/2" hose for our larger pump units.  Follow this link to access our lock-on hose fittings.
