What This Product Does

The seal closes the gap at the bumper-to-body junction, helping limit the accumulation of moisture and road dirt behind the bumper. It also provides separation between adjoining surfaces and contributes to a tidy finish during bodywork repairs or restoration.

Functions

• Forms a sealing barrier at the rear bumper joint.
• Helps keep dirt and moisture away from adjoining bodywork.
• Limits rubbing and vibration between neighbouring surfaces.
• Restores the appearance of the bumper-to-body junction.

Technical Details

• Part reference: 90150509220.
• Component identified in the supplied diagram as a lateral seal.
• Application context: rear bumper assembly for Porsche 911 up to 1968.

Symptoms of Fault

• Rubber that has become brittle, split or visibly shrunken.
• Flattened areas or missing portions of the seal.
• Uneven gaps along the bumper joint.
• Rattling accompanied by worn seals or loose fixings.
• Dirt and dampness collecting behind the bumper.

Why Replacement Matters

Renewing a deteriorated seal helps re-establish the bodywork joint and reduces places where grit and moisture can collect. OE Match develops replacement components around Porsche applications, making this seal relevant to repairs and classic-car restoration. Inspect the adjoining panels, bumper mounts and fixings before fitting; a replacement seal cannot correct corrosion, damaged hardware or poor panel alignment.

FAQs

Will replacing the seal eliminate every rear-end rattle?
No. Check bumper attachments and surrounding components as well.

Should the fixing hardware be inspected?
Yes. Replace damaged or loose retaining components where necessary.

How should the fitting area be prepared?
Remove trapped dirt and old residue, inspect for corrosion, and fit the seal without stretching it.

The rear bumper seal creates a weatherproof barrier between the bumper and the body panel. It prevents water, road debris, dust, and contaminants from penetrating the space where the bumper meets the vehicle structure. In addition to protection, it helps maintain a tight, factory-correct joiner surface that reduces wind noise and vibration.

Over time, original bumper seals can harden, shrink, crack, or split from heat, aging, and exposure to road conditions. When worn, seals can allow:
• Moisture ingress leading to corrosion
• Wind and road noise
• Dirt intrusion under body panels
• Visible gaps or uneven bumper fitment
Replacing a worn/recovering seal restores the correct factory sealing and finish - maintaining the visual integrity and long-term protection of your classic Porsche.

Replace this rear bumper seal if you notice:
• Cracks, splits, or missing rubber
• Loose or uneven bumper alignment
• Water entry or dampness near the rear panel
• Excessive wind noise while driving
• During bumper removal or restoration work
