Designed for speed and efficiency, the Mission Blak-JAK Washpipe Cartridge System is a self contained unit designed to be repacked on the rig floor, not at the swivel.
Once the assembly has been repacked, the single cartridge can be installed quickly in the swivel just by tightening the nuts to the gooseneck. A spanner bar is utilized to tighten the nuts, eliminating the use of hammers. Since the packing does not rotate with the nuts on installation, most of the installation can be accomplished by hand. The Mission Blak-JAK washpipe cartridge is also 25% lighter than OEM designs to aid in maneuverability at the swivel and the rig floor. Since installation of the washpipe packing is accomplished on the rig floor and not at the swivel, personnel time aloft is greatly reduced, thereby promoting a safer workplace.
The Mission Blak-JAK washpipe cartridge system utilizes standard packing and washpipe, with optional high temperature resistant packing available. No modifications to the swivel or gooseneck are required to install the Blak-JAK washpipe cartridge system and periodic lubrication requirements are identical to the OEM unit.
