Featuring a 1/2" Sweat (ODF) connection and a standard 1-14 UNC thread size, this Rotalock valve kit provides a robust transition point for high-pressure refrigeration circuits. As a technician-grade refrigeration service valve, it is engineered to facilitate easy compressor swap-outs and system evacuations without losing the total refrigerant charge. This kit serves as the direct OEM replacement valve for legacy part numbers 998-0510-40 and 998-0510-44, ensuring seamless compressor compatibility for ZP50-57K3 and ZP61-83KC models. The assembly includes the necessary PTFE seals to maintain a leak-proof interface under standard operating pressures. By utilizing this HVAC sweat-to-rotalock adapter, contractors can ensure their installs meet factory specifications while reducing downtime during critical repairs. This unit is built for durability in both commercial and residential applications where reliable isolation and port access are mandatory.

Common Questions

• Is this valve compatible with A2L refrigerants? Yes, this Copeland series is rated for use with modern refrigerants, provided the system pressures do not exceed the valve's rated maximum.
• Does the kit include the Rotalock Teflon gasket? Yes, the 998-0510-98 kit typically includes the necessary seal (part no. 020-0028-00) to ensure a tight connection to the compressor port.
• Can I use this for both suction and discharge lines? While sized at 1/2", it is specifically designed for ports matching the 1-14 UNC thread; always verify your specific compressor's suction/discharge port sizes before installation.
