Copeland 998-0034-04 Adapter Kit

For professional contractors, the Copeland 998-0034-04 is a critical Stub Tube to Rotalock Adapter Kit designed for high-pressure refrigeration and AC environments. This OEM Copeland adapter facilitates a secure transition from a 1-3/8" ID stub tube to a 1-3/4"-12 male Rotalock fitting. Engineered with a heavy-duty steel body and a robust aluminum flange, this kit is built to withstand the rigorous vibrations of commercial HVAC systems. The 1-3/8" inside diameter ensures a precision slide-fit connection for suction line brazing, while the precision-machined threads provide a leak-proof seal essential for maintaining system charge and efficiency. This HVAC replacement part is typically utilized in large-tonnage Copeland scroll compressor installations where field-brazing a Rotalock valve directly to the stub is required for maintenance or system retrofitting.

• Precision Interfacing: Seamlessly converts 1-3/8" stub tube lines to 1-3/4"-12 Rotalock connections without compromising flow.
• Industrial Durability: The carbon steel and aluminum construction prevents galling and resists corrosion in high-cycle refrigeration units.
• Superior Seal Integrity: Designed to work with standard Teflon seals (included in some kit variants) to eliminate high-side or low-side leaks.
• Fast Installation: Simplifies compressor replacement and piping modifications in the field, reducing billable labor hours.

What is the primary application for the 998-0034-04 kit?
It is primarily used to adapt standard copper tubing to a Rotalock-style connection on large industrial compressors, allowing for easier valve serviceability.

Does this kit include the Teflon seal?
Most Copeland 998-0034-04 kits come as a complete assembly for a single connection point to ensure an airtight seal during the first install.

Is brazing required for this adapter?
Yes, the stub tube side of the adapter is designed to be brazed onto your HVAC system copper line, while the Rotalock side provides a threaded mechanical connection.
