When to choose it

Choose the B3720 if the part you need is the enclosure around a T19 tip. Hakko supplies the nut with the enclosure. This is a service part for the iron setup, so identify whether you need the enclosure or the working tip before placing an order.

Hakko USA documents the B3720 for the FX-601. Use the iron’s exact model and tip arrangement to confirm fit before replacing parts. If the enclosure is fine and you only want a different face width, compare a compatible T19 tip instead.
