The CURTIS wc-66170 is a gray tube extension measuring 3.0 inches in length, designed for use in systems that require a short, fixed-length conduit or tube fitting extension. This type of component is commonly used to bridge connection gaps, extend probe or sensor reach, or adapt existing tubing runs where a precise length is needed. Installation is typically handled by HVAC technicians, plumbers, or refrigeration service professionals working on equipment that calls for standardized tube fitting extensions.
The wc-66170 is suited for applications where a 3.0-inch gray tube extension is specified by the equipment design. Its compact length makes it appropriate for tight-clearance installations inside equipment cabinets, control panels, or inline plumbing assemblies. The gray color coding may indicate a specific sizing or material class within the CURTIS product line, which technicians should verify against the original equipment specification before installation.
Designed as an OEM-style replacement tube extension for systems specifying a 3.0-inch gray tube extension in the CURTIS product line.
Installation of tube extensions should be performed by a qualified technician familiar with the equipment being serviced. Shut off power and isolate any fluid or refrigerant pressure in the system before beginning work. Verify that the extension length, diameter, and end fittings match the original component specification before installation. Follow all applicable codes and the equipment manufacturer's service documentation.
