Freshwater Tank Fill Port Plastic Plug - Only for 2005, 2006 and 2007* RT RS Adventurous Model

The original 193-P plug no longer available?

The 153-P is the direct replacement part for your fresh water tank fill port plug. Designed by the same manufacturer as the original, this center-pull tapered plug fits securely inside the white covered hatch under the rear passenger seat (just inside the sliding door). It creates a tight seal to keep out dust, dirt, bugs, and rodents.

While slightly shorter than the original 193-P, the 153-P sits even more securely in the recessed port hatch.

Key Features

• Easier Removal: Center pull tab extends above the flange for a quick, easy grip.

• Durable Construction: Heavy-duty tab is molded directly into the plug so it won't snap off.

• Snug Seal: Tapered design ensures a tight, reliable fit.

• All-Weather Material: Made from tough low-density polyethylene (LDPE) rated for extreme temperatures.

Specifications

• Part Number: 70100176890001

Verified Fitment

Fits the following Roadtrek (RT) models built on the T1N Sprinter Chassis:

• 2005 Roadtrek RS Adventurous

• 2006 Roadtrek RS Adventurous

• 2007 Roadtrek RS Adventurous (First-half build year only)

Chassis Identification Note for 2007 Models:

Early 2007 RS Adventurous models were built on the T1N chassis (identified by 5 wheel lug nuts). Later 2007 models shifted to the NCV3 chassis (identified by 6 wheel lug nuts). This plug is verified for T1N builds, though it may also fit mid-year NCV3 models with the same white fill hatch.

Other Roadtrek Models:

May fit other Roadtrek models equipped with the square white freshwater fill hatch near the passenger sliding door, but fitment on other models has not been verified.
