MRP-1000 Series Crest Diameter and Ovality Gages - 1" - 4-1/2" Tubing

Thirty years ago, Gagemaker introduced the MRP® crest diameter and ovality gage which forever changed the industry. Today, the MRP® series of gages is the industry standard worldwide. Whether you call it Crest Diameter, Root Diameter, or Ball PD, Pitch Diameter governs the strength of the actual thread assembly and ensures API dimensional measurement specs are met.

MRP-1000 Series Crest Diameter and Ovality Gages - 1" - 4-1/2" Tubing

The Gagemaker MRP® crest diameter gages measure the internal and external pitch diameters of tapered threaded connections. Any slight variations in diameter or ovality are immediately detected with these precision gages allowing the operator total control over the quality in the threads they are producing . MRP® crest diameter gages are extremely versatile with 3 models that can can easily adjust to measure thread diameters ranging from 1½” – 20”. The ability to inspect and measure a range of internal and external diameters with one gage, eliminates the need for heavy, cumbersome, and expensive fixed limit ring or plug gages.

The gage uses two pivoting shoes that rest on the crests of the threads during inspection. Any variations in pitch diameter
detected during inspection are shown on the gage’s indicator.

Gagemaker offers both rod style setting standard and frame style setting standards which can be used to preset the MRP® Crest Diameter Gage.
