Heat shrink tubing

Heat shrink tubing is extremely useful for marking cable that is permanent and therefore accurate. They form a waterproof, protective barrier of insulation over damaged or exposed wiring and electrical connections.

The tubing is a great invention for when you need to repair wiring, identify circuits and conductors that are being used for switch lines. They are very easy and simple to use, while looking very neat and tidy.

After heating the tubing, they shrink roughly up to ½ of the original size, forming an extremely tight connection, which is safe after use. When cool, the material can be quite stiff, but still flexible enough to bend and twist into position.

Heat Gun

To accompany the heat shrink tubing, the heat torch is a very useful item that stops the damage to insulation that other methods involve.

Nimrod’s Micro-therm heat gun is a small but mighty tool which produces a 650°C hot air stream. Commonly used by electricians for heat shrinking cable tubing, it is a versatile tool and its uses extend to fast drying of adhesives, testing thermostats, thawing locks, speed-drying touch up paint and will also melt soft solder.

Its micro size aids the use of the heat gun in confined spaces, handheld and no cables involved.

The heat gun is easily refilled from butane gas lighters and will run for approximately 20 minutes, per fill. With safety at the forefront, it features a safety lock to prevent accidental ignition.
