Rubber Grommet 8x14x7 

Restore the original fit, protection and reliability of your Porsche with this OE Match Rubber Grommet (8x14x7mm), designed for a variety of applications on selected Porsche 911 models. Manufactured to original equipment specifications, this versatile rubber grommet provides secure mounting, vibration isolation and protection where cables and pipes pass through body panels or mounting brackets.

Fits:

  • Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
  • Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
  • Porsche 911 1978-1983 3.0L / SC
  • Porsche 911 1984-1986 3.2L
  • Porsche 911 1987-1989 3.2L G50

This OE Match grommet is used in several factory applications, including:

  • Brake master cylinder feed and return pipes.
  • Engine lid release cable (1974–1977).
  • Fuel flap release cable (1987–1989 models fitted with the plastic fuel expansion bowl).

Although small, this rubber grommet plays an important role in protecting components from wear, vibration and damage while helping maintain factory-quality fitment.

What Does the Rubber Grommet Do?

The rubber grommet provides a protective and cushioned interface between the vehicle body and cables or pipework.

Depending on its installation location, it performs several important functions:

  • Supports brake master cylinder feed and return pipes.
  • Protects hydraulic pipes from chafing against metal panels.
  • Supports the engine lid release cable.
  • Guides and protects the fuel flap release cable.
  • Prevents vibration and rattles.
  • Eliminates metal-to-metal contact.
  • Helps reduce wear caused by continual movement.

By securely locating these components, the grommet contributes to long-term reliability throughout the vehicle.

Why Do Rubber Grommets Fail?

Rubber components naturally age and deteriorate over time through constant exposure to heat, vibration and environmental conditions. Common causes of failure include:

  • Age-related hardening.
  • Cracking and splitting.
  • Compression causing loss of elasticity.
  • Oil, grease or brake fluid contamination.
  • UV and ozone exposure.
  • General wear after years of service.

Once the rubber loses its flexibility, it can no longer properly support or protect the cables and pipework, increasing the risk of wear and vibration.

When Should the Rubber Grommet Be Replaced?

Replacement is recommended whenever the surrounding components are removed or serviced, or if you notice:
Cracked or perished rubber.

  • Loose cables or pipework.
  • Flattened or compressed grommets.
  • Signs of cable or pipe chafing.
  • Missing or damaged grommets.
  • During restoration or preventative maintenance.

Replacing worn rubber grommets is an inexpensive way to restore factory fitment while protecting valuable cables and hydraulic components from premature wear.

About Wiper Motor

Wiper motors are vital components that keep your Porsche’s windscreen clear, providing safe visibility in rain, snow, or dirt conditions. Mounted beneath the windscreen cowl, the wiper motor powers the wiper linkage, converting electrical energy into the precise mechanical movement that sweeps the blades across the glass.

At Design911, we stock a comprehensive range of genuine and aftermarket wiper motors for classic and modern Porsche models - including the 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Every motor is designed for an exact fit and consistent, long-lasting performance.

What Do Wiper Motors Do?
The wiper motor is an electric drive unit that operates the windscreen wipers at variable speeds. When you activate the wiper switch, the motor’s internal gearing and armature generate rotary motion, transferring it through linkages to move the wiper arms.

A quality wiper motor ensures:

  • Smooth, even wiping across the windscreen.
  • Reliable performance in all weather conditions.
  • Integration with intermittent, low, and high-speed modes.

Why Do Wiper Motors Fail?
Over time, wiper motors can wear or fail due to a combination of mechanical and electrical issues, including:

  • Motor brush wear or corrosion: Common in older vehicles exposed to moisture.
  • Seized linkages or frozen arms: Increased resistance can overload the motor.
  • Electrical faults: Poor wiring, bad ground connections, or blown fuses.
  • Internal gear wear: Reduces torque and wiping efficiency.

Symptoms of a failing wiper motor include slow or uneven wiper movement, wipers stopping mid-sweep, or complete non-operation.

Why Replace Faulty Wiper Motors?
A defective wiper motor can severely compromise visibility and driving safety. Replacing it ensures your windscreen remains clear in all weather, maintaining safety, comfort, and MOT compliance.

By choosing a genuine Porsche wiper motor, you retain OEM build quality and longevity. For cost-effective repairs, aftermarket alternatives from trusted brands offer excellent performance and compatibility without compromise.

Design911 supplies both genuine Porsche and premium aftermarket wiper motors — all rigorously tested for reliability, precise fitment, and long service life.
