The TRANE 85109 is a flexible adapter designed for use in HVAC and plumbing drain line applications where a slip socket connection is required. Constructed from plastic, this adapter provides a reliable transition fitting that accommodates minor misalignments between mating components. At 4.25 inches in length, it is compact enough for tight installation spaces. The part is typically installed by licensed HVAC technicians or plumbers during equipment installation or drain line service work.
This adapter is suited for residential and light commercial HVAC systems where condensate drain lines or similar piping connections require a flexible transition point. The slip socket configuration allows it to seat securely onto compatible pipe or fitting ends without threading, simplifying installation in confined equipment areas. It is referenced by the supplier designation SFJ-100-W.
Designed as an OEM-style replacement flexible adapter for TRANE HVAC systems requiring a slip socket drain or transition fitting.
Installation should be performed by a licensed HVAC technician or plumber. Power down the unit and isolate any water or condensate flow before beginning work on drain line components. Ensure mating pipe or fitting ends are clean and free of debris before seating the slip socket connection. Follow applicable local plumbing codes and manufacturer guidelines when replacing drain line fittings.
