Washer bottle gasket. Porsche 911/912 68-73  ❭  90162818300

The OE Match Washer Bottle Gasket is a replacement sealing gasket used within the windscreen washer reservoir assembly on selected classic Porsche 911 and 912 models.

• Porsche 911 1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

Its purpose is to provide a secure seal within the washer bottle assembly, helping prevent washer fluid from escaping around the relevant reservoir connection or sealing point.

This small component is particularly important on older washer systems, where the original rubber seal may have hardened, shrunk, cracked or lost elasticity after decades of exposure to washer fluid, temperature changes and age.

What This Product Does:
The washer bottle gasket forms a liquid-tight seal within the windscreen washer reservoir assembly.

It helps:

• Prevent washer fluid leakage
• Maintain a secure seal around the washer bottle assembly
• Keep washer fluid contained inside the reservoir
• Prevent air entering where the system requires a sealed connection
• Support reliable washer-system operation
• Protect surrounding luggage-compartment components from washer-fluid leakage
• Restore the correct fit between ageing washer-bottle components

Although inexpensive and relatively simple, the gasket plays an important role in keeping the washer system leak-free.

Symptoms Of Wear Or Failure:
Common symptoms of a deteriorated washer bottle gasket include:

• Washer fluid leaking around the reservoir assembly
• Dampness around the washer bottle
• Fluid staining beneath the reservoir
• Washer fluid level dropping without frequent use
• Reservoir repeatedly becoming empty
• Wetness around the gasket or adjoining connection
• Hardened or brittle rubber
• Visible cracks in the gasket
• Flattened or permanently compressed seal
• Distortion or shrinkage
• Gasket no longer fitting tightly
• Washer fluid smell in the luggage compartment
• Reduced washer-system reliability

A leak should always be traced carefully because hoses, fittings, the bottle itself or the washer pump can produce similar symptoms.

Why Replacement Matters:
A worn gasket can allow washer fluid to leak continuously.

Continued use with a failed seal can result in:

• Repeated washer-fluid loss
• Washer reservoir running dry
• Windscreen washers becoming unavailable when needed
• Fluid contamination around nearby components
• Corrosion or deterioration of surrounding hardware
• Additional cleaning and maintenance
• Greater strain on ageing washer-system components

Replacing the gasket restores the seal without requiring replacement of the complete washer bottle where the reservoir remains serviceable.
