Copeland 998-0034-18 Adapter kit

The Copeland 998-0034-18 is a professional-grade Rotalock to stub tube adapter kit engineered for high-pressure refrigeration and air conditioning applications. This essential service component features a 1"-14 thread size female Rotalock connection paired with a 1/2" ID stub tube (solder) outlet, facilitating a secure transition between threaded valves and copper suction or discharge lines. Constructed from heavy-duty steel or high-tensile brass, the adapter is designed to withstand a maximum working pressure of up to 500 PSI, making it compatible with modern high-pressure refrigerants including R-410A, R-22, and R-407C. The inclusion of a Teflon seal ensures a leak-proof interface, critical for maintaining system vacuum integrity and prevent refrigerant loss in commercial scroll or reciprocating compressor setups. As a genuine OEM Copeland compressor part, this 1/2" sweat adapter provides the precise tolerances required for field retrofits and immediate hardware replacements where a 1"-14 Rotalock interface is present.

• Universal Compatibility: Seamlessly adapts a 1"-14 Rotalock valve to a standard 1/2" OD copper line, supporting a wide range of condensing unit and evaporator configurations.
• High-Pressure Rated: Engineered to handle the rigorous demands of R-410A systems with a robust 500 PSI pressure rating.
• Leak-Proof Connection: Supplied with a resilient Teflon gasket to establish a dependable mechanical seal against the Rotalock face.
• Durable Construction: Built from technician-preferred materials to resist vibration-induced fatigue and thermal cycling in demanding HVACR environments.
