Description
The Trane CPL0938 is a genuine OEM 2×3 reducing coupling designed to join two different pipe sizes in HVAC systems, making it easier to adapt and connect ductwork or piping during service and repair. This coupling features a female 2″ end and a female 3″ end, providing a secure and leak-resistant transition between mismatched diameters. Constructed from durable materials suitable for HVAC environments, the CPL0938 is built to resist corrosion and provide long-lasting performance. Easy to install with standard tools, this reducing coupling supports proper airflow or condensate/drain routing in residential and commercial systems. Using an OEM coupling helps ensure proper fit and avoids common leakage issues contractors see with generic adapters.
