Copeland 998-0034-15 Adapter Kit

The Copeland 998-0034-15 is a professional-grade Rotalock adapter kit designed to transition a 1/2" I.D. stub tube to a 1"-14 thread size connection. Engineered for high-pressure refrigeration and air conditioning environments, this OEM Copeland service part facilitates a leak-resistant seal between the compressor and the system piping. The kit typically includes the brass adapter body and a Teflon O-ring seal (gasket), ensuring compatibility with modern refrigerants and oils. This stub tube to Rotalock adapter is a direct replacement for 034-0047-00 and is frequently utilized in Daikin McQuay and various commercial condensing units. For technicians performing field retrofits or compressor change-outs, the 998-0034-15 adapter provides a reliable, threaded interface that simplifies future maintenance by eliminating the need for repeated brazing at the service valve connection. Its robust brass construction is designed to withstand thermal cycling and vibration inherent in heavy-duty HVACR applications.

• Precision Threading: Features a 1"-14 TPI Rotalock thread for a secure, airtight fit with standard service valves.
• Optimized Flow: Designed for 1/2" stub tube I.D. to maintain system pressure characteristics without excessive restriction.
• High-Compatibility Seal: Includes a Teflon seal compatible with a wide range of synthetic and mineral oils.
• Durable Construction: Heavy-duty brass body prevents stripping and resists corrosion in harsh environments.
• Direct OEM Replacement: Replaces part numbers 034-0047-00 and Daikin McQuay 300000413 for seamless integration.

What is the primary application for this adapter kit?
This kit is used to convert a standard 1/2" copper stub tube on a compressor or component to a 1"-14 Rotalock threaded connection, allowing for the use of Rotalock valves and easier component isolation.

Does this kit include the necessary seals?
Yes, the 998-0034-15 typically includes the required Teflon gasket/O-ring to ensure a proper seal at the threaded interface.

Will this fit a 1-1/4" Rotalock thread?
No, this specific model is designed for a 1"-14 thread. If your application requires a 1-1/4" or 1-3/4" thread, you will need a different Copeland adapter series.
