This is a 4mm wire sleeving.\r\nThis is a PVC wire sleeving.\r\nPVC is an effective and cost efficient wire insulator.\r\nThe colouring of this PVC wire sleeving is green and yellow.\r\nThis is great if you need to change the colour of the wire to allow the wire to stand out.\r\nThis is also very useful for re-insulating a wire if the previous insulator has come loose, or bare wire is showing.\r\nThis green and yellow 4mm wire sleeving is included in our 1 year guarantee, as are all of our products on our website electricals247.co.uk.
