This grommet is used in the washer bottle / washer pump assembly on various Porsche models.

What This Part Does / Functions
•  Seals the washer pump into the washer fluid reservoir
•  Helps prevent washer fluid leaks around the pump opening
•  Supports and cushions the washer pump in the bottle
•  Helps maintain correct pump positioning
•  Replaces a hardened, cracked, split or leaking original grommet
•  Helps restore washer system reliability
•  Provides correct OE Porsche rubber fitment
•  Supports correct reassembly after washer pump or washer bottle service.

Why Replace This Part?
Washer pump grommets are exposed to washer fluid, age, temperature changes and repeated pump removal. Over time, the rubber can harden, shrink, crack or lose elasticity. A worn grommet may allow washer fluid to leak from the reservoir or cause the pump to sit loosely in the washer bottle. Replacing it with an OE Genuine Porsche washer pump grommet helps restore the correct seal and secure factory fitment.

Common Symptoms of a Faulty Washer Pump Grommet
•   Washer fluid leaking from the reservoir
•   Fluid dripping around the washer pump
•   Washer pump loose in the bottle
•   Cracked, hardened or perished rubber grommet
•   Washer fluid level dropping when the car is parked
•   Poor sealing after washer pump replacement
•   Dampness around the washer bottle area
•   Grommet damaged during pump removal.

When to Replace This Part
•   When replacing the washer pump
•   When removing the washer pump from the reservoir
•   If washer fluid is leaking around the pump seal
•   If the original grommet is cracked, hardened, split or missing
•   During washer bottle replacement
•   During windscreen or headlamp washer system repair
•   When restoring the washer system with correct OE Porsche parts
•   Whenever the grommet no longer seals the pump securely.

Where It Fits on the Car
This grommet fits in the washer fluid reservoir / washer bottle, where the washer pump pushes into the bottle opening. It acts as both a mounting bush and sealing gasket for the pump. Depending on model and equipment, it may be used for the windscreen washer pump and/or headlamp washer pump where specified.

About Washer pumps / bottles / jets

Washer Pumps, Washer Bottles & Washer Jets – Clear Vision for Every Drive

Washer pumps, bottles, and jets are key components of your Porsche’s windscreen cleaning system. They work together to deliver washer fluid from the reservoir through the pump and jets, keeping your windscreen clear of dirt, bugs, and debris for safe driving visibility in all conditions.

At Design911, we supply a comprehensive range of genuine and high-quality washer system components - including washer bottles (reservoirs), electric washer pumps, and precision spray jets — for all Porsche models such as the 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Every part is designed to offer high levels of fitment and performance for dependable cleaning power and long-term reliability.

What Do Washer Pumps, Bottles and Jets Do?

  • Washer Bottle / Reservoir: Stores the washer fluid and is typically located in the engine bay or boot area.
  • Washer Pump: An electric motor that pressurises the fluid and pushes it through the lines toward the 
  • Washer Jets / Nozzles: Deliver a fine, even spray of fluid onto the windscreen or headlights for effective cleaning coverage.

Together, these components ensure your windscreen remains clean and streak-free, maintaining visibility and safety in all weather conditions.

Why Do Washer Components Fail?
Over time, washer system parts can degrade or fail due to wear, contamination, or environmental exposure. Common causes include:

  • Pump failure due to internal corrosion or debris blocking the impeller.
  • Leaking washer bottles from cracks, freezing, or age-related wear.
  • Clogged jets caused by limescale, dirt, or poor-quality washer fluid.
  • Electrical issues such as damaged wiring or corroded connectors.
  • Perished hoses or seals leading to fluid leaks and reduced pressure.

Symptoms of failure include weak or no spray from the jets, fluid leaks, or a pump that doesn’t activate when the washer stalk is used.

Why Replace Faulty Washer Components?

A properly functioning washer system is essential for visibility and road safety. Replacing worn or damaged components ensures your windscreen remains clean and clear in all driving conditions.

Benefits of replacement include:

  • Restored washer performance and pressure.
  • Improved visibility and safety in rain or road spray.
  • Prevention of leaks and electrical damage.
  • High-quality parts for perfect fitment and durability.
