Febi Bilstein 29752 NBR Coolant Tube Seal Ring – Black

The Febi Bilstein 29752 is a high‑performance NBR (nitrile‑butadiene rubber) seal ring designed specifically for coolant tubes in automotive cooling systems. Its black coloration not only provides a classic, professional look but also masks any minor discoloration that may occur during long‑term use.

Key Material Characteristics

NBR (Nitrile Butadiene Rubber) is renowned for its exceptional resistance to:

• Coolant chemicals and additives
• Temperature fluctuations ranging from –40 °C to +120 °C
• Mechanical wear and tear under continuous pressure cycles

This combination of chemical stability and thermal resilience ensures that the seal ring maintains a tight, leak‑free fit throughout its service life.

Design Features for Optimal Performance

• Precision‑milled profile: Guarantees a perfect match with standard coolant tube dimensions, reducing installation time and eliminating the risk of misalignment.
• Dual‑layer construction: The inner layer offers high compression strength while the outer layer provides excellent resistance to coolant solvents.
• Black finish: Enhances visibility during maintenance checks and protects against UV degradation when exposed to sunlight in open cooling systems.

Applications Across Vehicle Brands

The 29752 seal ring is engineered to fit a wide range of vehicles, including but not limited to:

• Audi – from A2 and A3 models to the high‑performance Q5 and TT series.
• Volkswagen – suitable for Golf IV, Golf V, Polo, Passat, and Beetle variants.
• Seat – compatible with Ibiza, Leon, Alhambra, and Exeo models.
• Skoda – fits Octavia, Fabia, Yeti, and Superb series.

Its universal design allows it to be used in both OEM and aftermarket cooling systems without compromising integrity.

Installation Guidelines

1. Clean the tube: Remove any debris or old gasket material before installation.
2. Align the seal ring: Ensure the groove on the coolant tube matches the profile of the ring.
3. Insert gently: Slide the ring into place, avoiding excessive force that could deform the NBR material.
4. Check for leaks: After re‑assembling the cooling system, run a short test to confirm a leak‑free seal.

Maintenance Tips

• Inspect the ring periodically during routine service intervals.
• Avoid exposure to harsh chemicals other than standard coolant formulations.
• Replace the seal ring if you notice any signs of cracking, hardening, or discoloration.
