Description

The Reducer from 6″ Flange to 4″ Thread is a heavy-duty adaptor designed to connect a 4″ threaded control valve, distributor assembly, or fitting to an FRP pressure vessel with a 6″ flanged opening. It provides a secure, leak-proof connection between large filtration vessels and standard threaded water treatment components used in commercial and industrial filtration systems.

Manufactured from durable, corrosion-resistant polypropylene (PP) or Noryl, the adaptor is engineered to withstand demanding water treatment environments while providing long-term reliability. The bolted flange design ensures a secure installation, while the 4″ threaded opening allows easy connection of compatible distributors, mount heads, or control valves.
