Thetford Polar White Dust Plug for City Water Check Valve - 94206

This dust plug is used to prevent unwanted dust and debris from getting into your city water check valve. It is universal, but what really makes it stand out is its unique UV coating that prevents the harsh rays of the sun beating down on it. This is important, as most RV's and campers are kept outside, and heavily used during Summer months when UV rays are at their highest. UV damage can cause rubber and plastics to break down and become brittle, creating the need for replacement.
