This type of tube is used for wine-making, although I found it cheapest at my local boat shop. I formed a seal on one end by melting it inside a copper end-stop &#8211; the 15mm type used for plumbing. Hold the copper stop-end in a mole wrench and heat it gently on a gas hob, then gently feed the plastic tube into it. It takes a few minutes but the tube does eventually melt. When it\u2019s done, cool it in cold water and saw the copper end-stop off. You have a totally water-tight end-stop that will never come off or leak:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" size-full wp-image-49\" src=\"https:\/\/www2.harwoodfamily.id.au\/wp-content\/uploads\/2012\/05\/images_felix_PoolTemp1.jpg\" border=\"0\" alt=\" \" title=\" \" width=\"226\" height=\"128\" \/> <img loading=\"lazy\" decoding=\"async\" class=\" size-full wp-image-50\" src=\"https:\/\/www2.harwoodfamily.id.au\/wp-content\/uploads\/2012\/05\/images_felix_PoolTemp2.jpg\" border=\"0\" alt=\" \" title=\" \" width=\"226\" height=\"117\" \/><\/p>\n<p>Unfortunately you can only feed the cat-5 cable down about a metre of tube before friction prevents it going any further, but that was enough for me.
