How do I reduce PVC size?

Apply heat to the PVC with a heat gun until the PVC softens. Then, slide the other clamp onto the pipe and tighten both clamps to close the four cuts (above right). After the PVC cools, remove the clamps and check the fit. If the pipe is still a bit large, cut more slits and repeat.

What happens when you reduce pipe size?

In a fluid passing through a pipe, a reduction in the diameter of the pipe can compress the flowing fluid. It flows faster, which increases the flow rate. And if the diameter increases, then the flow rate reduces.

What is the opposite of swaging?

Expand
Swage(or reduction): Swaging reduces the tube’s outside diameter (OD), allowing one part to fit into another. Expand: Expanding increases the OD of a tube and is the opposite of swaging.
