Sherwood 4in Magnetic Quick Connection Dust Extraction Coupling Set

Great product. Makes changing to different machines so easy.

The product seems to work well. The fitting doesn't fit every type of machine, but with a short length of pipe you can adapt it.

It is not as strong as I'd hoped so it can't hold the weight of the extraction hose in my current set-up. I'm going to have to redesign my extraction system to get it to work.
