4" x 3" Reducing Configuration
This Type AA fitting provides a 4" x 3" reducing configuration, allowing compatible cam & groove components of different nominal sizes to be connected within the same fluid transfer system.
The reducing design provides a transition from the larger 4" camlock connection to a 3" camlock connection while maintaining an adapter-style connection on both ends.
Type AA Adapter x Adapter Design
The Type AA configuration features male cam & groove adapter ends on both sides of the fitting. Each adapter end is designed to connect with a compatible female camlock coupler.
This configuration supports quick, tool-free connection and disconnection within compatible cam & groove systems.
356-T6 Aluminum Construction
The fitting is manufactured from 356-T6 aluminum, providing a combination of strength, corrosion resistance, and lightweight handling.
The aluminum construction helps reduce fitting weight compared with heavier metal alternatives while providing durable construction for compatible fluid transfer applications.
100 PSI Maximum Working Pressure
The supplied product information specifies a maximum working pressure of 100 PSI.
System operating conditions and the pressure ratings of all connected hoses, couplings, and other components should be verified before the fitting is placed into service.
Cam & Groove Connection
Both ends of the fitting use male cam & groove adapter connections designed to mate with compatible female camlock couplers.
The cam & groove connection style allows fast assembly and disconnection without requiring threaded connections or tools for normal coupling operation.
Typical Applications
- Fluid transfer systems
- Hose connection applications
- 4" to 3" camlock size transitions
- Petroleum service
- Chemical transfer applications
- Agricultural applications
- Construction equipment and transfer systems
- Industrial fluid handling
Installation & Service Notes
Before installation, confirm that the system requires a 4" male cam & groove adapter x 3" male cam & groove adapter configuration and that the mating female camlock couplers are compatible.
Verify chemical compatibility with 356-T6 aluminum before use in chemical transfer applications. Inspect the fitting regularly for wear, damage, or conditions that could affect proper connection and sealing before service.

Our specialists can help with cam & groove reducers, adapter and coupler compatibility, connection sizing, and matching components for your fluid transfer system.
