Replacing Heat Shrink Tubing
Having to replace heat shrink tubing over electrical connectors can be a little challenging and even risky if not some correctly. Follow my few simple tips and tricks and you’ll have the job done in no time!
This has to be the most important think when attempting to do any work. Most people dive straight in and waste time on the job because they can’t find the tools they need. It is much quicker to get everything you need and then start as there will be no interruption during your work flow. This is especially handy if you are doing it for someone else as you don’t want to inconvenience them anymore then is necessary. Make sure you have all your tools, if you are working with wiring then make sure the electricity supply is switched off and you have access to the connection where the heat shrink tubing is located. You’re work area should be clean, tidy and free from hazards that could cause injury to you or anyone else.
REMOVING THE TUBING
Make sure the electricity supply is of! I say this twice as you would be surprised how many people forget this crucial step and end up hurting themselves. Carful cut the old heat shrink tubing to enable you to remove it from the wire. Do not cut through the wire but slice the heat shrink tubing length ways and then peel it off the connection. Discard this and inspect the area where the heat shrink tubing was placed. Because the connection is now exposed this is the perfect time to do a visual inspection and ensure everything is as it should be. If required, adjust the connection to conform to safety standards.
REPLACING THE TUBING
Everything is how it should be and we are ready to move on, I’m assuming? This is the home straight and the easiest part but make sure you take great care and this step requires a heat source. Place the heat shrink tubing over the connection ensuring that the whole conductor is completely covered. This is important as the heat shrink tubing acts as an insulator so missing this step could be dangerous. Using a heat source such as a heat gun, hair dryer or a blow torch (make sure you use a diffuser attachment if you are using a blow torch!). Gently pass the heat over the heat shrink tubing and it will slowly start to shrink. Keep repeating this until that tubing forms a tight sealed connection.
Make sure you leave your work area tidy and you clean up after yourself. There is nothing worse the making a mess and then having to clean it up later when you decide to do something else. If you ever have to attempt to replace heat shrink tubing then stick to these simple steps and get the job done like a professional!
