We have everything you need to install a central vacuum or retrofit your old one. Two inch outer diameter thin wall PVC vacuum pipe (and fittings) are standard in 99% of installations. If you have smaller pipe, there are pipe adapters below. Use standard PVC glue for pipe and fittings.
Our Installation home page is full of links on everything you need to know about installation.
