Tinel-Lock Adapter and Ring
This termination system consists of a modified spin-coupling adapter with a Tinel-Lock ring. 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 adapter. The adapter entry size and ring designator must be selected to suit the cable diameter and braid type. The resulting 360o termination withstands severe shock, vibration, temperature cycling and corrosion. Straight, 45o and 90o configurations are available.
Tinel rings are marked with a termochromic paint, which changes color when the correct installation temperature is reached.
Braid type, material and construction are variable. Refer to drawing CH00-0250-008 for Tinel-Lock Adapters.

AS85049 Adapters and Band Straps
The band strap termination system provides ease of installation and repair. The self-coupling locking nut provides an improved mechanical protection against loosening under vibration. There are two forms of band that are available - precoiled and straight.
