Someone has previously asked this question but it has not been answered properly.
Hi WeAreElectric,
The spec of our Plastic Cable Gland kits doesn't include any component identified as a rubber sleeve, although the tails glands do come with a plastic rod to insert in the Earth wire hole if it isn't being used, so in order to ensure we are answering about the part you are referring to we will need to see a picture of it.
You can send a picture to us direct at:- technical.support@bgelectrical.co.uk
