Mechanical Tubing End Locator

The Tubing End Locator disc spring mechanism, which supports the dogs in the open position, can be repeatedly functioned as chosen. The quantity of disc springs installed can be varied to give the desired indication loads for a particular application. If, for some reason, the dogs become jammed as a result of debris ingress, the emergency shear feature can be activated by upward jarring. This function produces enough movement to un-support the dogs, enabling tool retrieval.

A variety of dogs can be supplied to suit profiles or tubing innerdiameters. Additionally, the pull through/push through load can be adjusted to suit specific applications.
