Intermediate Diameter Internal Pipework Electrode – 32mm-45mm


Ideal for use with our range of DC holiday detectors and available with an M8 mounting thread as standard with options available for M12 or M20 thread attachment; this electrode system provides a highly-effective, reliable and gentle way of testing – without the risk of damaging – coatings applied to the inner surface of pipework sections.

The two silicone-rubber electrode discs have cut-outs to aid flexibility without adverse distortion and are offset from each other to ensure contact is made with the entire circumference of the coating. The red spacers ensure the electrode discs do not become stuck together.

The silicone-rubber contact discs are precision-made and optimised to suit their stated test range. They are easy to replace and offer excellent contact and conductivity.

We also manufacture a range of electrode systems for inspecting smaller and larger pipework diameters.
