Not all copper tube terminals are tested to perform. TQ™ is.

We partnered with DEKRA - one of the world’s most respected and independent certification bodies, operating for over 100 years - to put our TQ™ copper tube terminals through the toughest testing in the industry.
Certified from 10mm² to 630mm² to BS EN 61238-1:2003
Why Certification Matters

If your terminals aren’t certified to BS EN 61238-1:2003, the trusted standard for copper connectors, there’s no guarantee they’ll perform under heat, load, or fault conditions.
That puts your project, your team, and even your insurance at risk.
A Complete System You Can Sign Off
TQ™ Certified Terminals + SWA Calibrated Tools = SWA Approved System
When used with our calibrated crimping tools and control-issue dies, TQ™ terminals form an SWA-approved termination system, which has been tested by us for total performance and reliability.
It’s not just DEKRA-certified components - it’s a complete, consistent solution you can trust.
