BSPP Go Solid Ring Gage - G1/8
These gages checks parallel threads. However it checks the external threads instead of the internal threads. They utilize GO/NOGO members and the standard for this gage is ISO 228-1 and ISO 228-2.
ISO 228-1 covers pipe threads where pressure-tight joints are not made on the threads. ISO 228-2 covers the limit gages for pipe threads where pressure-tight joints are not made on the threads. BSPP thread plug gages have 55 degree thread profile. This specification covers many GO and NOGO gages that are used to verify different elements of the thread. The GO gage insures that the profile of the machined piece does not exceed the maximum of material provided for by the tolerances applied to the dimensions of the profile defined by ISO 228-1. The NOGO gage for the threads of the pieces fix the minimum material limit on the flanks of the thread. These gages are available in full form style compliant with the ISO specification or a modified style manufactured in the United States. The full form BSPP thread ring gages are made in a solid style and are available in Class A and Class B. The Class A GO BSPP ring gage are also compatible for Class B threads and are calibrated with a wear check plug gage. The NOGO Class B gage are quoted on request.
