I want to replace the tip with one with a different size bore. To get the original one in I ducked the end of the hose in hot water and pushed it in, fixed in place with a jubilee clip. Can't dip end in hot water as hose has grit in it. I have heard, a hair dryer can accomplish the same as hot water. The tip is 10 mm OD and is tungsten carbide. To help pull the tip out I was thinking of a pair of pliers but even though TC is hard, think tip is also brittle, so I could damage it, using pliers to help pull it out? Attached photo of hose in cabinet. Thanks.
