This packet of 2 pair of Deans Compatible T-Connectors are made from Nylon, making them very tough and difficult to melt, even with the worst of soldering skills.
Perfectly compatible with the original Deans connectors, with the added advantage of moulded-in ridges on the side of the connector making connecting and disconnecting easier.
They also include a rubber over which slides over the exposed soldered terminals, so there is no need to use heat shrink.
