Description: The 8191 is an Internal Taper Gauge for use on API Casing, Tubing, and Line Pipe in sizes from 1~8-5/8″ ID, in addition it can be used on small diameter API RSC and to check ring groove diameters in couplings. The moving arm utilizes linear bearings, similar to those found on earlier models, to maintain a remarkably smooth and stable 1″ travel. This prevents arm rotation for more accurate measurements up to 4-1/4″ from the face. The lower sliding arm quickly accommodates sizes from 1″ to 8 5/8″ ID through a precision dovetail locking mechanism. Naturally, it will also accommodate interchangeable Tungsten Carbide contacts, allowing it to be used on various thread types. This easy-to-handle and extremely durable gauge is one of our proudest moments.
The dial indicators have a travel of either 1/2″ or 1″, graduated in 0.001″ increments, with a required API accuracy of 0.001″ over their entire range. The metric dial has graduations of 0.01mm and complete compliance to API specifications through the 25mm range. It also accepts the complete range of Allen Contact Points.
All taper gauges are furnished with 2 Allen Ball Points, a certificate of compliance to API specifications and a fitted box.
All taper gauges, except the 5619 and 5624, are furnished with a fitted carrying case.
