The large end of this connector fits into Schedule 20 PVC, while the smaller
end attaches to any 4" dust hose. The PVC connection requires silicone
adhesive and the hose can be fixed with a metal clamp (neither are included). Schedule 20 (PVC sewer pipe) is thin walled PVC pipe commonly found at home centers.
Fitting is made from ABS plastic.
Note regarding Schedule 20 PVC: The term "Schedule 20" merely refers to the wall thickness of the pipe. When inquiring at your local sources, it is best to ask for thin wall sewer/drainage pipe (rather than asking for "Schedule 20"). It may be difficult to find this pipe via online sources as it is typically sold in 10 ft. lengths.
