| On-Off Tool The Harbison-Fischer On-Off Tool is a positive and dependable means of connecting and disconnecting the sucker rods from the sucker rod pump. It is normally installed just above an Oversize Tubing Pump plunger or is used to disconnect the rods above a stuck pump, eliminating a rod striping job. The lower key lock is available in an H2S resistant material and the upper body can be ordered in an oversize version for heavy pumping installations. It is available for tubing or casing sizes from 2-3/8" through 7-1/2". |
