this the right locknut for a -04 size Aeroquip Hi-Po fitting, or do I need something different?
Answer by: Customer Support on Dec 9, 2025, 4:02 PM
For -04 size Aeroquip Hi-Po applications, this is the correct match. It carries the AN 924 designation, comes from Eaton Aeroquip directly, and the catalog number C1CQ59 lines up with what Hi-Po fitting assemblies call for in that dash size. If your fitting is -04 and you're working with Aeroquip Hi-Po components, you're in the right place.
