Vacuum hose adapters for PVC pipe

These PVC pipe to vacuum line adapters are on my dust collection system going to the Radial Arm saw. They could be used for any other propose like just to extend a vacuum hose over a distance with PVC

From a 1.5" PVC pipe into a standard vacuum line to the top of the Radial arm saw.

From a 2" PVC pipe into standard vacuum line to go to the catch box behind the saw. I used 2" PVC here because I may redesign that catch box and it will then use a 2" vacuum line.

As an after thought I'm also including a 3rd adaptor. Its for a standard vacuum line to a 2" PVC pipe but has a way to mount it to a wall stud to help support the line. It will be on my 3rd branch off the main of the collection system and go to the Table saw. I just have not printed that one yet.
