Tru-Thread Ltd are a well established company in the oil and gas industry, supplying API gauges to major manufacturers for twenty years.

Tru-Thread Ltd is the only company in Europe that is approved to manufacture and calibrate all three API gauge specifications 5B,7 and 11B.

Tru-Thread Ltd has the largest range of API Reference Master Gauges in Europe, enabling us to offer a comprehensive manufacture and calibration service where certification to a master gauge is required.

Where possible we will rework customer submitted gauges that have failed periodic calibration, this cost effective against the manufacture of a replacement gauge.

In addition to API gauges we manufacture and calibrate customer designed gauges for specialist applications for both offshore and onshore facilities. These incorporate taper gauges of various thread forms, seal gauges and function gauges.
