Lubricants or seals are required in case of any break, wear or tear that needs to be fixed. They act as high-level glues for sticking the broken parts together and keep the functionality of the item maintained. Sticking of water pipes to prevent leaks,tubes, wood, plastic chairs, toys and many other items can be done with the help of a multipurpose lubricant.
Sometimes, these lubricants can be used just for a make-shift arrangement and not as a permanent solution. But mostly, they work as the best when it comes to fixing broken things and thus they save the cost of buying a new item as a replacement of broken one.
