ORB-006 – O-Ring, -006, BUNA

The AqMatic ORB-006 is a Buna-N O-ring used in diaphragm valve assemblies and internal rebuild kits for water treatment, filtration, and industrial flow control systems.

This O-ring functions as a sealing component within the valve assembly, helping maintain pressure integrity between internal chambers and preventing leakage during valve cycling. Proper O-ring sealing is critical in diaphragm valve systems because pilot pressure and diaphragm response depend on maintaining consistent internal pressure separation.

The ORB-006 configuration uses Buna-N (Nitrile) elastomer, a material commonly selected for standard water treatment and industrial fluid handling applications due to its durability and resistance to oils and general process fluids. Buna O-rings are widely used throughout V42 diaphragm valves and K53 series valves because they provide reliable sealing under repeated cycling conditions.

This component is typically replaced during valve rebuilds alongside diaphragms, springs, seals, and internal hardware in systems controlled through stagers and automated valve sequencing assemblies.
