Ellis Shear Tool

ELLIS SHEAR TOOL

The Ellis Shear Tool is run above the pump to enable easy retrieval of the rod string. Ellis Shear Tools are used with fiberglass sucker rods to retrieve the rod string in case of a stuck pump preventing costly fishing jobs. Ellis Shear Tools are designed to fail at an accurate pre-determined breaking load. It is available in shear release of 18K, 21K, 26K, 33K and in all API sucker rod pin sized.

It is recommended to clear tight spots in the tubing string and clean any paraffin present in the well before installation to prevent premature failure of the shear tool caused by impact load when the pump scopes out through paraffin or a tight spot.

High quality machining processes adopted at Ellis Manufacturing allows us to maintain extremely close tolerances and produce components with smooth surface finishes and chatter free threads.
