Keystone NI1590102 Rear Door Opening Weatherstrip Seal - Nissan Sentra 2020-2023

The Keystone NI1590102 is an OEM-replacement rear door opening weatherstrip seal designed for the 2020–2023 Nissan Sentra. Engineered to match the original factory specification, this seal installs on the body along the rear door opening and applies equally to both the driver and passenger sides (RH=LH), simplifying inventory and ordering for collision repair professionals and DIY installers alike.

Weatherstrip seals play a critical role in vehicle comfort and integrity — blocking wind noise, water intrusion, dust, and road debris from entering the cabin through the door gaps. Over time, the original rubber seal can crack, harden, compress, or tear, leading to annoying wind noise, water leaks, or drafts inside the cabin. This Keystone replacement restores the tight, factory-quality seal your Sentra's rear doors require.

Key Features:

• Direct OEM-style replacement for factory part 76924-6LE0A
• Fits the rear door body opening — mounts on the body surround, not on the door itself
• RH = LH — single part number fits both driver and passenger sides
• Designed specifically for the 2020, 2021, 2022, and 2023 Nissan Sentra
• Restores OEM-level sealing against wind noise, water, dust, and road debris
• Made to match original dimensions and rubber profile for a precise, no-modification fit
