Delrin insulation for the 26-E hammer electrode
The insulating component in the head of the 26-E hammer electrode assembly. Delrin is used here because it is dimensionally stable, machines accurately and holds its insulating properties under the repeated shock loading a slide hammer applies.
Why it is a service part
On a resistance meter, the insulation between the two pin circuits is what makes the reading meaningful. If it degrades or cracks, current leaks between the circuits and the meter reads high — a wet reading on dry timber. It is a quiet failure, because the meter still switches on and still displays a number.
If a hammer electrode has started reading consistently high, or reads a moisture content with the pins in clear air, suspect the insulation before you suspect the meter.
Fitment
Supplied for the Delmhorst 26-E hammer electrode assembly. Delmhorst does not publish a specification for this part in its online catalogue, so we have not stated dimensions we cannot verify. If you are servicing a 26-ES or 26-ED, send us the electrode model and we will confirm the correct insulation part before you order.
