Definitions include: Is slang for synopsis you usually find it at the back of a novel e.g boy in striped pyjamas, and you use it informally like when you 're talking to a friend, you can't use it formally like when you're talking to your boss.
The reason a flaring tool exists is to cut a piece of soft copper tubing, apply a flare fitting, and provide a waterproof seal without soldering. It is often preferred to use flared copper pipe when water or gas will be going through the tube.
Not sure if the 14  is just added insurance or what. Anyway I found a guy that suggested instead of buying the 45.00 flaring tool use a bolt and a nylok nut. When you buy the brass tubes one end is already flared, generally this goes to the outside. He then suggested using a long bolt or threaded rod.
