The AQ Matic 1074166 Custom Repair Kit is a 421 series rebuild kit designed to restore sealing performance and valve response in diaphragm-operated systems. This configuration includes both internal components and diaphragm/seal (D/S) elements, allowing for a complete functional rebuild rather than a partial repair.
Used in water treatment, filtration, and industrial fluid handling systems, this kit addresses the common issue of uneven performance caused by wear across both sealing surfaces and internal valve components. Replacing only one element often leaves residual inconsistency in cycling and shutoff. This kit resolves that by restoring the interaction between internal parts and diaphragm sealing surfaces as a matched set.
The 1074166 kit is built for AQ Matic 421 valve assemblies, ensuring proper fitment and reliable operation under system pressure. It is typically used during scheduled maintenance or when valves begin to show delayed response, minor leakage, or inconsistent cycling behavior.
