Thick Heat shrink tubing 56 to 17 mm X 20 cm
Thick heat shrink sleeves, 20 cm long. Use diameter 56 to 17 mm (shrink ratio 3:1). Interior covered in a thermoplastic resin. Ideal for aerial self repair.
Thick heat shrink sleeve containing a completely thermoplastic covered interior surface.
On heating, the diameter of the sleeve reduces by 3:1, 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.
• This high diameter sleeve is ideal for aerial self repair. We use it to cover the 40m and 30m coils on DXBeam antennas that we produce (see photo above).
• 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.
