The 3021 Diverter is manufactured to work on your casing. It can be flanged to casing, threaded on casing, or can be made up with the compression lock system. The compression lock system is simple and foolproof. Simply slide the diverter over casing and tighten 3 bolts on compression ring. The rubber rings enclosed are then compressed around your casing providing a slip-proof lock and seal on plastic casing as well as steel.
It utilizes the 3010 series stripper rubber. Because of the 3010's two-piece construction, bit and/or hammer can be lowered into casing by simply opening the stripper rubber, passing the tool, and closing back around drill pipe. Drill cuttings are now contained and diverted to desired location through the flow line.
