PVC & CPVC Fittings
- Precision welds with fine tolerances
- Rugged, durable PVC/CPVC construction
- Sizes from 4" to 24", custom options
6 x 4 PVC Reducer Couplings provide a socket-end transition between different duct or piping diameters in industrial ventilation systems. Built from PVC or CPVC with rugged construction, fine tolerances and inspected precision welds, they support plastic fan installations, ductwork and chemical air-handling applications, with custom sizes available on request.


The available PVC and CPVC fitting range includes multiple size configurations from 4 inches to 24 inches. A 6 x 4 reducer coupling is intended to connect different diameter sections using socket-end connections. Custom size reducers are also available upon request, so provide the required connection sizes and application details when requesting product guidance.
