In the world of luxury automotive parts, NOS typically stands for New Old Stock. These are genuine, original parts that were manufactured years ago but were never sold to a customer or installed on a vehicle.

For a Bentley, NOS fittings are highly prized because they offer the exact factory fit and finish of a vintage or discontinued model while being in “brand new” condition.

What Are Bentley NOS Fittings?

Bentley NOS parts are usually sourced from old dealership inventories or the Bentley factory archives. They are especially common for:

• Classic & Heritage Models: Parts for the Arnage, Azure, or Turbo R that are no longer in active production.

• Hydraulic & Fuel Systems: Connectors, adapters, and pipe fittings that must meet high-pressure factory safety standards.

• Trim & Brightware: Chrome fittings or “jewelled” accents that are difficult to replicate with aftermarket alternatives.

Where to Find Genuine Bentley NOS Parts

Since these are limited-supply items, they are typically found through specialized heritage suppliers rather than standard modern dealerships.

Important Verification Steps

Buyer Beware: Because the term “NOS” is also a famous brand for Nitrous Oxide Systems, searching for “Bentley NOS fittings” can sometimes pull up high-performance racing adapters. Always verify that the part number matches the Bentley Heritage Catalog.

• Check the Packaging: True NOS parts often come in original, slightly weathered Bentley or Rolls-Royce branded boxes with the original part number stickers.

• Inspect Seals: For hydraulic fittings, ensure any rubber O-rings or seals haven’t become brittle (dry-rotted) from sitting on a shelf for decades.

• Part Number Suffix: Ensure the suffix matches your vehicle’s specific “modut” or build specification.
