Emerson Alco 065668 Screw Adapter

The Emerson Alco 065668 (Model OMB-ACA) is a precision-engineered screw adapter specifically designed for the integration of OMB and OMC electronic oil level management systems into high-performance refrigeration circuits. Featuring a 3/4" x 14 NPTF thread connection, this adapter is the professional standard for technicians retrofitting Copeland Scroll compressors, including Glacier, ZF, ZS, and ZB models. By replacing the existing sight glass, the Emerson 065668 adapter enables seamless mounting of oil controls to maintain optimal crankcase lubrication and prevent catastrophic compressor failure. This high-density component is rated for a maximum working pressure of 640 psi, ensuring mechanical integrity in demanding HVACR screw adapter applications. When executing a Copeland compressor oil level control installation, this NPTF screw adapter provides a leak-proof interface that simplifies field service and improves overall system reliability without requiring extensive piping modifications.

• Direct Compatibility: Optimized for Copeland Scroll ZF, ZB, ZR, and ZS series, ensuring a perfect fit for electronic oil level control systems.
• High Pressure Rating: Engineered to withstand 640 psi maximum pressure, making it suitable for HFC, HCFC, and CFC refrigerant environments.
• Streamlined Installation: Facilitates 3/4" x 14 NPTF mounting by directly replacing the factory sight glass, reducing labor time on the job site.
• Technical Precision: Maintains the required 30-40 ft-lbs torque specification for a secure, vibration-resistant seal in industrial settings.

Which compressors are compatible with the OMB-ACA adapter?
This adapter is specifically utilized for Copeland Scroll models such as the Glacier, ZF, ZS, and ZB series where a 3/4" NPTF connection is required for oil management.

Does this unit require additional gaskets for mounting?
The adapter is designed for direct replacement of the sight glass. It is recommended to use the O-ring provided with your OMB/OMC control unit to ensure a vacuum-tight seal during assembly.

What is the recommended torque for the NPTF connection?
For secure integration, the Emerson Alco 065668 should be torqued to 30-40 ft-lbs, ensuring the 3/4" x 14 NPTF threads are properly seated to prevent oil migration.
