A PVC bushing works by fitting inside a larger PVC fitting to reduce its diameter, allowing you to connect pipes of different sizes.
Essentially, a PVC bushing functions as a reducer. It's designed to be inserted into a fitting that's too large for the pipe you want to connect. Think of it like an adapter.
Here's a breakdown of how it works:
- Spigot and Slip Connection: PVC bushings usually have a "spigot" end and a "slip" (or socket) end. The spigot end is smaller in diameter and is designed to fit inside a larger fitting (the slip fitting). The slip end of the bushing is sized to accept a smaller diameter pipe.
- Diameter Reduction: The primary function is to reduce the diameter of the fitting it's inserted into. For example, you might have a 2-inch fitting and want to connect a 1-inch pipe. You'd use a 2-inch to 1-inch bushing.
- Permanent Connection: PVC bushings are typically solvent-welded (glued) into the larger fitting and the smaller pipe is then solvent-welded into the bushing, creating a permanent, leak-proof connection.
In summary, a PVC bushing is a simple yet effective fitting used to adapt between different pipe sizes in PVC plumbing systems, by reducing the inner diameter of a larger fitting.
