The connector was designed to fit the Titan Wet and Dry Vacuum Pipe End Connector.. It was designed for a plumber that was installing a new boiler at me home and his original one broke and asked me if I had any glue to repair it. The original design is bad as it has weak points and was also was bad for suction. This is a replacement connector for the end of the hose where it fits into the Vacuum body itself. It has been re-designed to that it is a lot stronger, easier to clean and the internal curves give better suction. The component has been 3D Printed and there are two options, a rigid version and a semi flexible version. If you require a version for a different vacuum than please send me a message and I will work with you to create you a custom part.
