Move your connector quickly from one machine to the next with this 4in threaded splice connector. The thread allows you to "turn" the hose on to one end for a secure fit and the other end is tapered slightly larger than the normal 4in outlets found on most machines so it will provide a snug fit but quick removal to move to the next machine as required in a workshop.
These Sherwood Threaded Connectors have far better thread mechanisms than our competitors, ensuring that the nice smooth attachment movement you're searching for is a breeze and they stay in shape for longer under heavy use and serious workshop conditions.
Please note that its still recommended to secure the hose on the threaded end with a dust hose clamp
