PVC Pipe Plugs are available as "External Cavity" and "Internal Cavity." In both cases, the plugs glue into a PVC Pipe Fitting, not the pipe itself. (If you are looking for plugs that glue into the pipe itself, see our Inside Pipe Plugs.) To help understand the difference between internal and external cavity plugs see the picture to the right. All plugs are hollow inside. The hollow part can be open to the fluid in the pipe (internal cavity) or open to the outside of the pipe (external cavity.) Not all plugs are available both ways. 1/2", 3/4", 1" and 1-1/4" are usually available either way. But 1.5" and larger are usually internal cavity plugs only.
If you required one style over the other, please put this information in the "comments" box on the check out page and we'll do out best to comply with your request.
(Note, the illustration to the right shows glue in fittings, but the threaded plugs on this page are just that, threaded.) Thank you! |
