Long Heat shrink tubing 12-3 mm

If you are looking at a classic heat shrink tube such as can be found more or less everywhere you will without doubt be in for a surprise as the model chosen by DX Avenue has nothing in common, other than it is heat shrink.


Thick heat shrink sleeve containing a completely thermoplastic covered interior surface.

On heating, the diameter of the sleeve reduces by 4:1, and the interior resin melts. On cooling, the sleeve and the resin harden. This combination guarantees resistance to pullout and a perfect waterproofing for your connections, the whole preventing a sleeve from slipping. In the case of a connector mounted on a cable (coaxial for example), this sleeving ensures a reinforcement at the place where the cable is generally subject to stress when the radius of the curve is low (see photo above) or the cable is suspended.

Notes and Suggestions from DX AVENUE

• To shrink this sleeve, use a classic hot air gun (heat stripper) which can be found at a reasonable price in store.

• If you overheat the sleeve slightly (heavy shrinking), it will happen that the sleeve will slip a little.  That is simply due to the fact that the interior resin has melted. You have sufficient time to slide it into its proper place before the sleeving hardens.

• To remove a sleeve, use a Stanley knife to cut it along its length (delicately if it covering a cable). The resin can be removed with thinners (white spirit, acetone...). However, if from the outset your connection is intended to be able to be removed, use instead a self amalgamating ribbon or waterproof mastic of the type we also sell.  The heatshrink sleeve is primarily intended for a permanent installation.
