RV Plumbing Vent Coupler Kit-Xtreme Vent
Xtreme Vent, RV Coupler Kit, extends the camper plumbing pipe when it's too short to install the Xtreme Vent (31-8293) wih this 1-1/2" internal ABS coupler.
Xtreme Plumbing Vent needs at least 3/4" of vent pipe showing to
be installed. This coupler kit will simplify the process without
disturbing any vent base which may be in place. The white coupler fits
inside the pipes, while most commercially available couplers fit outside
the pipes, which would not work.
