Cars are made up of lots of interconnected components, and couplings are an important part of joining the pieces together. Half inch couplings are made for specific connections of two shafts or pipes, and once attached provide a secure way to link them together. Failing couplings are a common cause of car problems - you might notice vibrations or loud screeching noises if a coupling is wearing out. This may be because the coupling wasn’t installed correctly, or it may be a low quality component that’s worn out with age.
