PMC Lone Star manufactures API working, reference and regional master gages per U.S. Steel specification.
All of our gages are made of tool steel hardened to Rockwell C 60-62 and are cryogenically frozen to insure their stability. Each gage is put through a series of in-process and final inspections with tolerances to ±0.0002 of an inch (±5 μm). We then qualify each gage using a certified master gage, and provide a calibration report detailing the measured dimensions and the serial number of the master gage used for the inspection. The quality and reliability of our gages have made them the overwhelming choice of coupling shops, pipe and tube mills around the world.
Warranty: One year from the date of manufacture.
