“F” COLLAR STOP

 

The Type “F” Collar Stop is designed to locate in the collar recess of API upset and non-upset tubing. By lowering the stop to the desired depth and lifting upward, the latch springs are tripped allowing the stop arms to expand into the collar recess. Downward jarring on the inner mandrel pushes it down behind the collar stop arms locking them into place in the collar recess.
