Product Description

The patented Crossover dredge Ball Joint includes two replaceable wear liners which provide a streamlined and unrestricted flow area in any tilted position. The optimal flow conditions result in reduced flow resistance and major cost-savings in fuel and wear, which typically result in a very short return on investment.

Classic Ball Joint

The Classic dredge ball joint has proven its worth for over 30 years. It is known for its sturdiness, ease of connecting and simplicity. The design includes one replaceable wear liner in the case. The inside of the ball is protected by the dredge pipe, which runs through the ball.
