Lets you connect a 4'' dust hose directly to schedule 40 PVC plumbing pipe.
The large end of this adapter fits around Schedule 40 PVC pipe, while the smaller end fits inside a standard 4'' dust hose. A hose clamp is included for easy connection of the PVC end. The adapter is made from a combination of rubber on the PVC end and hard plastic on the hose end. Look for schedule 40 PVC at your local home center.
