knuckle joint tool for oil and gas well logging tool

Product Description


The knuckle joint is designed to add bending flexibility to the downhole toolstring to let it pass a kick-off point.

The tool incorporates a simple ball-shaped connecting mechanism which allows a limited turning angle of 10 degrees between X and Y axes.

The feed-through wire is protected in a small stainless steel through-wire tube. This knuckle joint features comparatively higher strength.
