Tinel-Lock Ring® Adaptors

The Tinel-Lock® ring is made from a special shape memory metal that shrinks uniformly when heated. The Tinel-Lock® ring is used to terminate copper cable braid directly onto the rear of the adaptor. The adaptor entry size and ring designator must be selected to suit the cable diameter and braid type. The Tinel-Lock® ring designator must be specified according to the type of cable braid used and is added to the part number after the adaptor entry size. There are two types of ring for each entry size, please see the PDF below for further information.

Note: Tinel rings are marked with thermochromic paint, which changes colour when the correct installation temperature is reached. The braid type, material and construction are variable. If in doubt, plese contact us for advice.
