The Dometic discharge tube kit 385312139 replaces the black discharge tube assembly used on compatible Dometic 85 and 8700 Series RV toilets. It is a high-intent repair part for leaks, damaged tube ends, or a worn discharge connection where the original tube assembly needs to be replaced rather than patched.

Features & Specifications

  • Genuine Dometic discharge tube kit
  • Part number 385312139 for exact replacement matching
  • Fits compatible Dometic 85/8700 Series toilet applications
  • Black molded discharge tube with formed bends and end details
  • Hose clamps shown with the kit photos
  • Useful for restoring the discharge connection on the toilet assembly

Why Choose This Dometic Discharge Tube Kit?

This kit is for shoppers who need the exact Dometic tube shape, not a generic hose. The molded bends, end openings, and included clamps matter because the discharge path has to line up correctly inside the toilet installation.
