Rubber Seals

Bumper horn piping seal. 1700MM.
Genuine Porsche Original Equipment (OE) bumper guard beading strip - often described as bumper horn piping seal or bumper piping beading. It is a rubber sealing/trim strip designed to fit along the edges of the front or rear bumper overriders (horn guards) on classic Porsche models.

Fits:
Porsche 911/912 1965 - 1973
Porsche 356B / 356C 1960 - 1965

The bumper guard beading/bumper horn piping seal provides a protective, weather-resistant edge between the rubber or chrome bumper guard and the surrounding body/bumpers. It hides gaps and edges, prevents water/mud ingress behind trim, cushions minor knocks, and completes the look of the bumper assembly in line with factory design.

Function:
Installed along recesses in the bumper overrider or horn area, this beading:
•  Fills and seals gaps between the bumper guard and the bumper body
•  Protects finished surfaces from scratches and edge wear
•  Helps retain trim fitment under vibration
•  Preserves original appearance and detail on classic Porsche models

Original bumper beading on classic Porsche models often becomes brittle, cracked, or stretched over decades of exposure to sun, moisture, and road debris. Worn or missing beading detracts from the overall appearance and can allow moisture, dirt, and corrosion to develop behind bumper trim. Replacing with a fresh beading restores the correct factory look, protects costly bodywork and trim, and helps maintain value for classic vehicles.

When to replace:
•  Beading is cracked, brittle, or split
•  Original strip has shrunk or deformed
•  During bumper removal/install
•  As part of bodywork restoration Prior to concours or show preparation

The piping seal installs easily into the original grooves and mounting channels on the bumper profile, forming a neat protective edge that enhances both aesthetic and functional performance. It is ideal for classic restoration projects, bumper reassembly after removal, or when refreshing aging or brittle original piping.

The bumper horn piping seal bridges the gap between the chrome/painted bumper horn and the adjacent bodywork by providing a soft, contoured edge. It helps:
• Mask raw edges and transitions between components
• Protect surrounding paint and finishes from minor contact damage
• Reduce the ingress of dirt, water, and road debris behind the bumper trim
• Restore the classic factory-correct appearance of the bumper assembly.

Function:
Installed along the perimeter of the overrider (horn) section of the front or rear bumper, this rubber piping compresses slightly to grip the bumper and horn edges. Its profile maintains a consistent seal while allowing normal flex and vibration without loss of fit - preventing rattles and movement that can occur with brittle, aged original beading. 

With age, original bumper horn piping often becomes brittle, cracked, deformed, or lost, exposing underlying edges and hardware. This can detract from the vehicle’s appearance and allow water and debris to sit behind the bumper, potentially trapping moisture and accelerating corrosion. Replacing it with an OE Match seal restores the look and function of the factory assembly - preserving both style and protective qualities.

When to replace:
•  Original piping is cracked, shrunken, or missing
•  Bumper horn or overrider has been removed for service
•  Preparing a vehicle for restoration, sale, or show
•  When reassembling bumped or replaced bumper trim
•  Preventive refresh on aging rubber components
