Non Insulated Crimping

Following up from this thread : http://locostbuilders.co.uk/viewthread.php?tid=179408

My cheap ebay fan came with basic bullet so thought it was the perfect opportunity to use some of equally cheap ebay superseal connectors and test out my cheap ebay crimper - and was happily impressed with the quality of the crimp it gave.

Much better than the cheap ones... and you remembered to put the seals on before crimping. I forgot the seals on multiple occations.

It was cheap though... £8 for the crimper and less than a £1 per connector (£3.72 posted for 5x 2ways (both male and female sides))

To be honest the rubber seals are quite stretchy, I would exepect retrospectively adding them would be easy enough.

Except you are meant to crimp the seal with the terminal to assist with the sealing process

I have seen them done like that, but the crimping action can ruck the rubber and make the seal worse. The tickness of the insulation made it a pretty tight seal against the cable.

If tight use lubrication!

We used to use Hellerine oil when assembling military waterproof connectors

I dont plan on doing much amphibious driving so I would hope using these over standard open connections will surfice.
