Left-Hand to Right-Hand Female Hex Thread Adapters
Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.
At about a third of the weight of steel adapters, aluminum adapters are the lightest we offer. They resist corrosion in wet environments.

Rod Alignment Couplers
Increase cylinder life by fixing alignment problems between air or hydraulic cylinders and driven components. Couplers have a threaded end that moves to compensate for the angle of misalignment, reducing wear on cylinder bearings and seals. Couplers have a male and female end.
