iHelios Frequently Asked Questions

How do I install a Blue Butt Crimp correctly?

Strip the insulation to the correct length, fully insert each stripped conductor into each side of the connector, crimp securely with a proper crimping tool, and inspect to ensure a tight, reliable joint. (Best practices for butt connector installation)

How many can I buy and what is the price?

They’re sold individually at around £0.10 each, with options often available in bulk packs (e.g., 10, 25, 50, or 100 pieces) for larger projects.

Is it suitable for underfloor or ceiling heating installations?

Yes. It’s commonly used to join conductors in infrared underfloor and ceiling heating film systems, providing secure, low-resistance electrical continuity.

What cable size is the Blue Butt Crimp designed for?

This insulated butt connector is made for cables between 1.5 mm² and 2.5 mm² (approximately 16–14 AWG), making it ideal for common wiring tasks.

What material and insulation does it feature?

The connector features an insulated barrel, typically PVC or nylon, to ensure copper conductors are protected and insulated in electrical heating circuits.
