Porter-Cable 5140228-52 Manifold Assembly – Genuine OEM Replacement Air Compressor Manifold with Regulator
Part Number: 5140228-52
Category: Air Compressor Parts → Manifolds & Regulators → Manifold Assemblies
Type: Porter-Cable 5140228-52 Manifold Assembly – Genuine OEM Replacement Air Compressor Manifold with Regulator
The Porter-Cable 5140228-52 Manifold Assembly is a genuine OEM replacement air compressor manifold designed for compatible Porter-Cable and DeWalt portable air compressors. This complete manifold assembly serves as the central control hub for the compressor, connecting the pressure regulator, gauges, tank outlet, and air hose connection into a single assembly. The regulator is factory-installed and is not available separately, making this the correct replacement when the regulator or manifold becomes damaged or develops leaks. The assembly replaces previous part number 5140111-92.

Function of the Manifold Assembly
The 5140228-52 Manifold Assembly is designed to:
- Route compressed air from the tank to the outlet
- Regulate outlet air pressure
- Support attachment of pressure gauges
- Provide the connection point for the air hose
- Maintain safe and consistent air delivery
- Restore the factory compressor control assembly
Common Signs Replacement Is Needed
Replace the manifold assembly if you notice:
- Air leaking from the manifold or regulator
- Regulator no longer adjusts outlet pressure
- Cracked manifold housing
- Damaged threaded ports
- Broken regulator knob
- Pressure gauges no longer mounting securely
Because the regulator is integrated into the manifold assembly, failure of the regulator typically requires replacement of the complete manifold assembly.
Installation & Service Notes
Disconnect the compressor from electrical power and completely drain all air pressure from the tank before servicing.
Remove the air hose, gauges, and associated fittings from the existing 5140228-52 Manifold Assembly. Carefully disconnect the manifold from the compressor while noting the orientation of all fittings and tubing. Inspect the pressure switch, safety relief valve, gauges, and threaded connections for wear or damage before installing the replacement manifold. Apply an appropriate thread sealant where specified by the manufacturer, reinstall all fittings securely, and verify there are no leaks after repressurizing the compressor.
Important: Always depressurize the compressor before removing the manifold assembly. Use only compatible OEM replacement parts to ensure proper pressure regulation and safe operation.
Maintenance Recommendations
- Inspect the manifold regularly for air leaks or cracked fittings.
- Keep the regulator clean and free of dust or debris.
- Drain the compressor tank after each use to reduce internal moisture buildup.
- Check threaded fittings periodically for leaks.
- Replace damaged gauges or fittings as needed.
- Use genuine OEM replacement parts to maintain factory fit, accurate pressure regulation, and long-term air compressor performance.
