API 7-2 Rotary Shouldered Thread Gauges

API 7-2 Rotary Shouldered Thread Gauges

Northern Gauge manufacturers API 7-2 working gauges. All gauges include a certificate of calibration that has
traceability to an API certified reference master.* We have the most extensive API 7-2 reference masters on hand
in Canada. Our calibrations are completed at our ISO 17025 accredited lab with complete NIST or equivalent
traceable equipment.

     

We keep in stock most connections for Regular Rotary Shouldered Connections, Internal Flush (IF), Numbered Connections (NC), Full Hole (FH), Hughes External Flush (HEF), H90 & PAC connections.

     

If you are inspecting a box connection or internal thread then you will need a plug gage in order to inspect the
part properly. If you are inspecting a pin connection or external thread then you will need a ring gage to inspect
the part properly. If you require assistance with how to gage your part, please check out our tech tip section
(How to use API 7-2 gauges)
