ORE-030 – O-Ring, ORE-030

The AqMatic ORE-030 is an EPDM O-ring used in diaphragm valve assemblies and internal rebuild kits for water treatment, filtration, and industrial flow control systems. It functions as a sealing component within the valve assembly, helping maintain pressure integrity between internal chambers during valve cycling.

This configuration uses EPDM elastomer, which is commonly selected for water treatment applications due to its resistance to water, ozone, and many treatment chemicals. EPDM O-rings are frequently used in systems where Buna materials are not preferred because of chemical compatibility or operating environment requirements.

The ORE-030 specification corresponds to a specific O-ring size and groove profile used within AqMatic valve assemblies, including internal 5520-series configurations. Proper O-ring fit is critical because diaphragm valve operation depends on maintaining separation between pilot and flow chambers. Incorrect sizing can lead to pressure loss, inconsistent actuation, or internal leakage.

This component is commonly replaced during rebuilds alongside diaphragms, springs, and internal hardware in systems using V42 diaphragm valves, K53 series valves, and automated sequencing systems controlled through stagers.
