4mm heat shrink tubing

[Mike Hardy]

Hi, Somebody on here will have some 4mm Heat-shrink and use 12AWG wire. Will the heat-shrink slip over the wire before shrinking?

Yes, Mike - I use 4mm h/s on 12AWG for my XT60 connectors

Hi Peter, Just ordered several colours from **LINK** at 16p/ meter.

AWG 12 = 3.3mm2 and has a diameter (flex) of approx 2.5mm - shouldn't be a problem.

Hi VA, I have just measured my 12AWG and the overall diameter is 4.4mm, so 4mm heat-shrink is going to be a tight fit!

Firstly different makes of silicon wire have a different thickness of insulation, so you will get some variation.

If you follow Mike's link to Rapid, they sell heat shrink in sizes 3.2mm 4.8mm, 6.4mm and 9.5mm. It does not say whether these are internal or external dimensions. It is best to assume they are external dimensions.

However, as the heat shrink has a 2:1 shrink factor, the 6.4mm heatshrink will reduce down to 3.2mm.

Rapid's prices are so cheap that it is worth buying a whole bundle of colours and sizes whilst paying for the postage (about £4) which will then last for many seasons, and yet cost less than the few tiny scraps found in packets in the LMS.
