tree monkey Posted July 29, 2020 Report Share Posted July 29, 2020 Any advice on choice of wire crimps, just for the standard boat wiring, not battery crimps. I've got a reasonably decent set of crimpers, it's just what would be considered decent crimps. It's not urgent just a general enquiry, thank you in advance 1 Link to comment Share on other sites More sharing options...

BEngo Posted July 29, 2020 Report Share Posted July 29, 2020 First make sure your crimping tool matches the crimps! There are tools for bullets, tools for uninsulated, toolsfor pre insulated, tools for MC4 and they are all different. If you are using the common small mole grip type, with red, blue, and yellow dies (holes) for various cable sizes then I have found Vehicle Wiring Products do a decent quality range of the pre insulated crimps in the various sizes, including rings. Loads more on Amazon and Ebay. If you are feeling flush there are heat sealable pre insulated ones, which should be better in damp environments. Ray T has beaten me to it. Then there are the aircraft types.... N 1 Link to comment Share on other sites More sharing options...
tree monkey Posted July 29, 2020 Author Report Share Posted July 29, 2020 Basically I'm looking for recomendations for a half decent set to carry on the boat for routine small jobs, nothing fancy just not cheap rubbish that will fail as soon as you look at it Link to comment Share on other sites More sharing options...

I've used them many times over the years and built up a fair stock of terminals. They're one of those things that get much cheaper per unit when bought in larger quantities Having read your posts again I see that you are looking for a 'selection box'. The trouble with those is that the popular sizes get used up very quickly Edited July 29, 2020 by Slim Link to comment Share on other sites More sharing options...
pearley Posted July 29, 2020 Report Share Posted July 29, 2020 As has been said, the heat shrinkable, adhesive lined crimps are the ones to use. Link to comment Share on other sites More sharing options...

Yes, crimp and heat shrink are good to use. I'm pretty sure ISO 10133:2012 frowns on soldered connections - that you weren't talking about! - but don't have a copy to hand. @Alan de Enfield might have it though.

Hellerman Deutsch ( I think, could have been AMP) made a pre insulated heat sealed crimp way back when I was just learning about wire locking. Nowt wrong with the principle, but I entirely agree with the last sentence. N Link to comment Share on other sites More sharing options...
