The stop ring design is a one-piece model that slips over the pin end of the pipe and is secured with set screws. Ray Oil Tool Company stop rings have a superior holding force and are especially applicable in close tolerance situations. The stop collars are manufactured from tubular steel or high-grade alloys to allow the centralizers a flat service to contact. The flat surface allows the centralizers a smooth bearing surface for rotational applications.

The stop rings are available in a full range of sizes from 2 – 7/8″ thru 20″.
