    Product Description

    Knurled couplings are devices that connect two separate shafts or pipes.  Knurled couplings have a series of ridges or grooves on the edges which differentiates them from other couplings. These patterned knurl designs offer a better grip to the coupling. Typically, these couplings are preferred in applications where there is a chance of slippage due to grease, oil, or other substances. Our advanced manufacturing capabilities and vast industry experience enable us to manufacture a wide array of couplings to customers across various industries.
