POLISHED ROD COLLET BUSHING
As polished rods may flex due to misalignment, polished rod failures may occur at the bottom thread of the polished rod. Installed between the polished rod and the remainder of the rod string, Black Gold's Polished Rod Collet Bushing eliminates the risk of polished rod pin failures.
The polished rod pin is threaded into the collet body. The nut is threaded onto the body, wedging the tabs between the nut and the polished rod. This specific design is tailored to have maximum holding strength as more tensile forces are applied to the collet bushing.
