IEC frame size motor terminal boxes and imperial size conduits

[PaulBr]

Does anyone has recommendations how to connect imperial size conduits to metric sizes openings in motor terminal boxes.
Machine is being built in China. All motor equipment is using IEC motors with metric size openings terminal boxes. However all conduits and fitting required to be PVC coated, hard to be purchased in China, and are coming from US. Are there some conduit fitting adapters on the market? Is it possible to replace motor terminal box with imperial size opening.

Thank you,
PaulBr.

Hawke, Peppers, and Raxton (all in the UK) make top quality metric-NPT adaptors.
