Apply heat to the PVC with a heat gun until the PVC softens. After the PVC cools, remove the clamps and check the fit. If the pipe is still a bit large, cut more slits and repeat. I used the same process to shrink a 1 1⁄ 2 " pipe to fit my vacuum-hose nozzle.
Besides, does PVC pipe expand when heated?
Like all materials, PVC expands with increasing temperatures and contracts with decreasing temperatures. Because the length-to-diameter ratios of PVC pipe and conduit products are generally very large, length change from temperature variation is the most noticeable.
- Insert a 3/4" Size PVC pipe segment into the 3/4" Pipe to 1-1/4" Fitting PVC Size Adapter.
- Press or tap into place until the pipe is fully seated inside the adapter.
- Insert the Adapter into the socket of a 1-1/4 in.
Subsequently, one may also ask, can you melt PVC pipe together?
Melting PVC plastic can be a very simple project depending on your reason for melting it. If you simply need to melt the PVC enough that it is pliable, a heat gun will get the job done. If you need to melt the PVC to the extent that you can mold and shape it, you will need a double boiler.
How to Measure the Outside Diameter of PVC Pipe
- Look at the end of a piece of PVC pipe.
- Find the widest point across the opening.
- Measure from the outside edge of the pipe to the opposite outside edge.
- This measurement is the outside diameter or "OD" of the pipe.
