Tapered Master Plugs


We also manufacture Taper Master Plugs (TMPs). A TMP is used for the manufacture and checking wear condition of ring gauges. A TMP has three lines inscribed as depicted in the diagram below; a new ring will be manufactured to fit between the first two lines. When the ring passes over the third line, the ring is worn.


When a TMP is used in the manufacturing of new rings, it ensures that all new ring gauges are consistent in size and allow you to monitor ring wear simply and accurately. This is useful when multiple rings are supplied to be used by subcontractors and end users.
