Information
O-ring wheel bearing spacer ring - 25,3 x 2,4
This OE Match O-ring is a replacement sealing ring used with the wheel bearing spacer ring on classic Porsche 911 and 914 models. It is designed to match the original-style fitment and provide a secure seal within the wheel bearing / hub assembly.
Sold each - 2 required per car
Fits:
Porsche 911 - 1965 to 1989
Porsche 914 - 1970 to 1976
Diagram ref no 23
The O-ring helps seal the spacer ring area in the wheel bearing assembly, preventing grease loss and helping keep dirt, moisture, and road debris away from the bearing components. A correct seal supports smooth wheel bearing operation and long-term hub reliability.
Functions
• Seals the wheel bearing spacer ring area
• Helps prevent bearing grease from escaping
• Helps protect wheel bearing components from dirt and moisture
• Supports correct wheel hub and bearing assembly
• Helps maintain smooth bearing operation
• Replaces hardened, flattened, cracked, or missing original O-rings
• OE Match replacement for wheel bearing and hub service work.
Why Replace This Part?
O-rings can harden, flatten, crack, swell, or perish over time due to age, grease exposure, heat, and road conditions. A worn or damaged O-ring may allow grease loss or contamination around the bearing spacer area, which can contribute to bearing wear, noise, or reduced service life. Replacing the O-ring during wheel bearing work helps restore a reliable seal.
When to Replace This Part
• The wheel bearing or spacer ring has been removed
• The original O-ring is cracked, flat, brittle, swollen, or missing
• Grease is leaking around the bearing spacer area
• Dirt or moisture has entered the hub/bearing assembly
• The wheel hub or rear axle assembly is being serviced
• Wheel bearing noise or wear is being investigated
• As preventative replacement during bearing or hub reassembly
Where it fits on the car
This O-ring fits in the wheel bearing / hub assembly, where it seals the wheel bearing spacer ring. Depending on the model and axle layout, it may be used in the rear hub or axle bearing area where part number 99970108450 is specified.
