There is a variety of thread forms in use in the electrical industry, matching the thread form or size of the gland to that of the equipment is a fundamental problem that is solved by using thread converters.

The main thread types are:

• ISO Metric – Most IEC countries
• NPT or National Pipe Taper – Used in North America
• BSP or British Standard Pipe
