If you’ve ever used an air compressor, you know that having a reliable and secure hose coupling is essential to a successful outcome. A universal joint or U joint connects an air tool hose to a compressor, quickly and easily. These universal couplings are quick connect fittings that snap into place to get you up and running with your air compressor fast.
