Copeland 998-5100-39 Valve Kit

The Copeland 998-5100-39 is a professional-grade Suction and Discharge Rotalock Valve Kit engineered for high-capacity refrigeration and air conditioning compressors. This kit features a 1 5/8" Sweat (ODF) suction connection with a 2 1/4-12 UNC Rotalock thread and a 1 1/8" Sweat (ODF) discharge connection with a 1 3/4-12 UNC thread. As a critical compressor service valve set, it allows technicians to isolate the compressor from the rest of the system during maintenance or replacement without recovering the entire refrigerant charge. Built from robust, high-pressure metals, these valves support a maximum operating pressure of 500 PSI and are rated for temperatures ranging from -40°F to +250°F. The precision-machined ODF sweat connections ensure a leak-free, hermetic seal when properly brazed into the liquid and suction lines. This OEM Copeland valve kit includes all necessary gaskets and O-rings, ensuring a direct-fit solution for keeping commercial HVACR systems operational with minimal downtime.

Key Benefits:

• System Isolation: Enables efficient compressor servicing by isolating specific sections of the refrigerant loop.
• High-Pressure Tolerance: Rated for up to 500 PSI, making it suitable for high-demand R-404A, R-407C, and R-22 applications.
• Leak Prevention: Precision Rotalock threads and high-quality seals prevent refrigerant loss and maintain system vacuum integrity.
• Full Kit Contents: Includes both suction and discharge valves plus required gaskets for a complete field installation.

Common Questions:
