Front bumper chrome moulding with impact rubber.
Narrow type 1/2 inch wide.

The front bumper chrome moulding with impact rubber is a direct-fit decorative and protective trim piece designed for the front bumper of classic Porsche 911 and 912 models (1965 – 73). This narrow-type moulding (½″ width) accurately replicates the factory profile, mounting hole spacing and chrome finish, incorporating a rubber insert to absorb minor impacts and protect the bodywork and finish.

Fits:
Porsche 911 1966 - 1973 (non S and RS)

Diagram ref no 2

•  Position on Vehicle: Front bumper — chrome moulding strip mounted across the bumper face, narrow style (half-inch width) with impact rubber insert.

• Applications: Ideal for restoration or repair of the front bumper trim where the original moulding is worn, corroded, missing or damaged, and where correct period appearance and trim quality matter.

The front bumper moulding serves both styling and practical roles: the chrome trim provides the classic look, while the rubber insert absorbs minor knocks and helps maintain the bumper edge finish. When the original moulding is faded, corroded, loose or missing, you may experience:
•  Visible gaps, mis-alignment or corrosion at the front bumper edge
•  Loss of protective rubber insert leading to chipped paint or damaged bumper edge
•  A less authentic appearance for a period correct vehicle
•  Difficulty sourcing correct mounting points or visible wear.

By replacing it with this moulding, you ensure the trim sits correctly, the finish is factory-correct, the protective rubber is present and the overall front bumper appearance and durability are restored.

When and why to replace:
•  Original moulding shows rust, pitting, bends, missing rubber insert or damaged ends
•  During front bumper replacement, bodywork respray or restoration project
•  Vehicle is being exhibited or resold and accurate period trim is desired
•  Loose or squeaking bumper trim indicates the rubber insert or mounting is worn

Diagram ref no 12 

The cross over pipe is exposed to high temperatures, vibration and exhaust gas pressure. The sealing ring washer helps maintain correct joint compression, reducing the risk of exhaust leaks, rattles and poor system alignment. When worn or damaged, the washer may no longer seal effectively, allowing exhaust gases to escape.

Replacing this washer during exhaust repairs, cross over pipe removal or restoration work helps ensure a professional, leak-free installation.

What Does an Exhaust Sealing Ring Washer Do?

An exhaust sealing ring washer supports the sealing joint between exhaust components. It helps maintain clamping pressure and assists the sealing ring or joint in preventing exhaust gases from escaping.

A correctly fitted sealing washer helps provide:

• Secure exhaust joint sealing
• Reduced risk of exhaust leaks
• Correct cross over pipe fitment
• Improved exhaust system stability
• Better gasket and sealing ring performance
• Reduced vibration and exhaust noise
• Reliable long-term exhaust operation

Symptoms of Wear or Failure

Common signs that an exhaust sealing washer may need replacement include:

• Exhaust blowing noises
• Soot marks around exhaust joints
• Increased exhaust noise
• Rattling from the cross over pipe area
• Poor sealing after exhaust refitting
• Corrosion or distortion of the washer
• Loose or uneven exhaust joint compression
• Exhaust fumes around the rear of the vehicle

Why Replacement Matters

A worn or damaged sealing washer can compromise the exhaust joint, leading to leaks, vibration and premature wear of surrounding exhaust parts.

Replacement helps:

• Restore correct exhaust sealing
• Prevent exhaust gas leaks
• Improve exhaust system reliability
• Reduce unwanted noise and vibration
• Maintain proper exhaust flow
• Protect connected exhaust components
• Improve repair and restoration quality
• Support long-term durability
