⚡ At a Glance
- • Seal Precision: Exact inner and outer diameters for accurate seating and reduced leak risk
- • Best for: Mechanics and DIY owners replacing injector seals on 1.6 TDI and compatible diesel engines

Reliable injection sealing - thanks to precise 6.70/4.85/1.85 mm dimensions
Outer diameter 6.70 mm, inner diameter 4.85 mm and thickness 1.85 mm are stated measurements for consistent fit. Tight tolerances help the ring sit correctly on injector return ports.
A correct dimensional match reduces the chance of fuel seepage and keeps the return line sealed during engine operation. Fitting the exact-size ring avoids premature failures associated with loose or oversized seals.
Wide vehicle compatibility - with multiple OEM reference numbers
Compatibility is established through extensive OEM references including 03L103070A, 9677759480, 1760803 and a long list of manufacturer part numbers. The listing names many 1.6 TDI models and several Ford diesel platforms.
Use the listed OE numbers to confirm suitability for specific A1, A3, Ibiza, Leon, Octavia, Golf, Polo and selected Ford Transit, Ranger and Defender diesel models. Matching references simplifies sourcing the correct seal for common European diesel engines.
Aftermarket OE-quality manufacturing - thanks to established European suppliers
Items are described as tested and supplied by leading European aftermarket manufacturers, with a stated OE Quality level. The listing emphasises testing and industry-standard sourcing.
