Copeland 998-0034-01 Adapter Kit

The Copeland 998-0034-01 Adapter Kit is a critical component for field technicians transitioning between stub tube and Rotalock connections on high-capacity refrigeration compressors. This OEM kit features a 3/4" Stub Tube I.D. (solder/sweat) for direct line integration and a 1-1/4"-12 thread size male Rotalock fitting. Engineered from heavy-duty brass, the rotalock adapter valve ensures a robust, leak-proof seal under high-pressure conditions typical of industrial HVACR environments. This service adapter kit often includes the necessary Teflon seal, replacing older part numbers like 034-0069-00 and Daikin McQuay 300000487. By utilizing this stub tube to Rotalock adapter kit, contractors can easily convert suction or discharge ports to a standard Rotalock configuration without extensive piping modifications, maintaining system integrity and efficient fluid transfer across various refrigeration replacement kits and compressor models.

• Optimized Compatibility: Seamlessly converts 3/4" OD copper lines to 1-1/4"-12 Rotalock ports common on Copeland compressors.
• Leak-Proof Reliability: Precision-machined brass construction with included seals prevents refrigerant loss and maintains long-term system vacuum.
• OEM Engineering: Replaces legacy part numbers 034-0069-00 and 300000487 for verified fitment and performance.
• Streamlined Installation: Simplifies field repairs and compressor swaps by eliminating the need for complex custom brazing or manifold reconstruction.

• What is the primary application for this adapter? It is used to adapt a sweat-style stub tube connection on a compressor to a threaded Rotalock fitting for easier servicing and valve attachment.
• Does the kit include the required seal? Yes, the 998-0034-01 kit typically includes the Rotalock adapter and the corresponding Teflon gasket/seal.
• Can this be used on both suction and discharge lines? It is compatible with any port matching the 3/4" I.D. and 1-1/4"-12 thread specifications, which are frequently found on suction ports of medium-to-large capacity scroll and semi-hermetic units.
