MWC1900 - Inner Waist Seal for Land Rover Defender Rear Side Door - Fits from 1983-2016 (Part Number: MUC1323 > MWC1900)

Seal (inner) for rear side glass of Land Rover Defender 110/130

MWC1900 inner seal for rear side glass of Land Rover Defender 110/130.

The part is installed on the inside of the doors along the lower edge of the window opening. The rubber working edge contacts the glass when it is raised and lowered, helping to prevent water and dirt from entering inside the doors.

The inner glass seal is part of the door construction and is in constant contact with the glass during the operation of the window lifter. Over time, the rubber may lose elasticity, deform, or become damaged. This affects the fit to the glass and can lead to moisture and dirt entering the door cavity.

Replacing the worn seal helps restore proper fit to the glass and maintain cleanliness inside the doors. When selecting, it is important not to confuse the inner seal with the lower edge glass outer seal.
