This 4 inch quick coupling allows you to attach the suction hose to the power jet with ease. Any restriction is eliminated because the suction hose fits inside the coupling and is locked into place with two clamps. A definite must for the serious dredger.
Please note that the coupling must be welded to the jet tube.
Comes complete with “bullet” that fits over your suction hose. The included rubber seal needs to be glued into the coupling once it has been welded into place.
