BLUMKRAFT Extension 20 mm for Thermostatic Valve M30 x 1.5 Compatible with Oventrop Unibox M30 x 1.5 Female/Male: Extends Your Thermostatic Valve by 20 mm (2 cm)
This is an extension cord, not an adapter.
For example, you can extend the regulator of your underfloor heating. This extension allows you to increase the distance between the thermostatic valve and the actuator.
You can also mount this extension cord in series (one extension cord on the other) to increase the distance even more.
Solid and precise:
The BLUMKRAFT adapter is produced in a single metal block, ensuring a much longer life than plastic adapters.
All measurements are 10th mm accuracy.
