Stainless Steel Faston flat 4,8mm For cable section from 1 to 2.5 mm Temperature max +400°C
These connectors (or “Faston”) are imported from Italy and match the size found in some espresso machines.
For better contact, we recommend using a crimping tool. If you’d like to invest in a better one, consider this style from Amazon: https://amzn.to/3M59DLQ
NOTE: So far, we cannot locate widely available covers/insulators for them, we suggest to use some heat shrinking tube. We DO NOT recommend insulating with electrician's tape.
