A precision-molded large rear window weatherstrip seal engineered to secure and seal the rear glass while protecting the vehicle interior from water, wind, and road noise. Designed with an integrated trim groove to accept a lockstrip (WCR D1048 T profile), this seal aligns and retains the glass, preventing leaks and reducing vibration. Constructed from durable EPDM rubber for long-term flexibility and UV resistance, it is ideal for restoration projects and direct replacement applications where an exact fit and reliable weatherproofing are required.
Features:
- Designed for rear window applications using the WCR D1048 T lockstrip profile.
- Durable EPDM rubber resists UV, ozone, and temperature extremes for long service life.
- Integrated trim groove accepts a lockstrip to secure and align the glass.
- Creates a watertight seal to prevent leaks and reduce wind noise and vibration.
- Flexible and resilient for easier installation and a factory-like fit.
- Ideal for restorations and replacement of worn or cracked rear window seals.
Installation / Application:
- Difficulty: 2/5
- Estimated time: 45–90 minutes
Instructions:
- Remove the interior trim and old weatherstrip, then carefully lift out the rear glass per vehicle service procedures.
- Clean the window channel and glass edge thoroughly with isopropyl alcohol to remove old adhesive, dirt, and sealant.
- Test-fit the new weatherstrip over the glass edge and into the channel to confirm orientation and fit. Trim excess if necessary.
- Apply a light coating of soapy water or approved window lubricant to the channel and seal to ease installation.
- If using a lockstrip, seat the lockstrip into the weatherstrip’s trim groove before installing the assembly into the channel.
- Starting at one corner, press the seal into the channel, working around the perimeter. Use a rubber mallet or block of wood to gently tap the seal fully into place without damaging it.
- Use a heat gun on low setting only if needed to make the rubber more pliable for tight corners; avoid overheating which can deform the seal.
- Trim any excess material with a utility knife for a clean finish and reinstall interior trim pieces and hardware to factory specifications.
- Perform a water test (hose) and check for wind noise; adjust or reseat the seal if minor leaks or gaps are found.
