This is a 4" quick disconnect with the spiral end. Your hose screws to one end and the other is tapered to slide over the machine fitting. Use when you have to move your hose from machine to machine a lot. These are made from thermal plastic and they are very durable. Please email me for a shipping quote on your dust collection needs.
