PVC reducing fittings are used to connect pipes of different sizes, allowing for smooth transitions between larger and smaller diameter pipes. Here are the common types of PVC reducing fittings:

  1. Reducing Coupling – A coupling that connects two pipes of different diameters in a straight line.
  2. Reducing Tee – A tee fitting where one outlet is smaller in diameter than the other two, used for branching connections.
  3. Reducing Elbow – An elbow fitting with one end smaller than the other, used to change the direction of flow while transitioning between pipe sizes.
  4. Reducing Bushing – A bushing inserted into a larger fitting to reduce its opening to fit a smaller pipe.
  5. Reducing Wye – A wye fitting with a smaller branch outlet, commonly used in drainage systems.
  6. Reducing Cross – A cross-shaped fitting with outlets of different sizes, connecting pipes at right angles while reducing size on one branch.
  7. Reducing Adapter (Male or Female) – Used to transition from one pipe size to another, with either male or female threads.
  8. Reducing Union – A union with different size ends, designed for easy disconnection of pipes of different diameters.
  9. Reducing Cap – A cap that fits over the end of a larger pipe but reduces the size of the connection to fit a smaller pipe.
  10. Reducer Insert Coupling – A coupling that reduces pipe size and is typically used in irrigation systems.

These reducing fittings come in both Schedule 40 and Schedule 80 varieties, depending on the pressure requirements of the system.
