Hazet 2169 Oil Filter Socket 14-Flute 74.4mm — 3/8" Drive, OEM Cap Fit

Hazet 2169 is a 14-flute, 74.4 mm oil filter socket with a 10 mm (3/8") internal square drive built to remove and install OEM-style oil filter caps precisely and without damage.

This compact, purpose-built socket fits a wide range of modern passenger cars and motorcycles and is designed to engage filter caps that use 14-flute profiles. Manufactured by Hazet, it delivers reliable contact with filter housings, reducing slippage and rounded edges during maintenance. The 74.4 mm diameter matches many common OEM filter caps from brands such as Mann, Knecht and Opel, and its inside square of 10 mm accepts standard 3/8" ratchets and extensions for easy garage or roadside use.

Which vehicles and filter brands does this socket work with?

The Hazet 2169 was made with compatibility in mind: it fits many current OEM filter caps and housings. It is suitable for Mann and Knecht filters as well as several factory oil filter caps used by Opel. It's also specified for Mercedes-Benz models since 2006, Audi models from December 2007 onward, BMW new-series F and K motorcycles and cars, and numerous Volkswagen models from 2007.

• Compatible with Mann, Knecht and Opel filter caps.
• Mercedes-Benz models: vehicles from 2006 and later.
• Audi models: vehicles from 12/2007 onward.
• BMW new-series F and K cars and motorcycles.

How does the 14-flute design improve filter removal?

The 14-flute profile increases contact area around the filter cap, distributing torque evenly and lowering the chance of rounding. That secure engagement helps you apply higher turning force safely with a 3/8" ratchet or breaker bar, especially on stubborn or over-tightened caps.

• 14 flutes provide multiple contact points to prevent slippage.
• Even torque distribution reduces damage to aluminum caps.
• Works well with extension bars for hard-to-reach housings.

What are the key dimensions and drive details to know?

The socket measures 74.4 mm across the engagement face and accepts a 10 mm inside square, which corresponds to a common 3/8" ratchet or driver. Those dimensions make it compact enough for tight engine bays while still offering a robust interface for applying torque.

• Engagement diameter: 74.4 mm (fits specified OEM caps).
• Flutes: 14-point profile for positive grip.
• Drive interface: inside square 10 mm (3/8" drive) for standard tools.

Can I use this socket for professional service and DIY maintenance?

Yes — Hazet 2169 suits both garage technicians and home mechanics who work on compatible vehicles. It pairs with common 3/8" ratchets, torque wrenches and extensions and is sized to clear many modern engine layouts where space is limited.

• Works with standard 3/8" toolsets used in workshops and home garages.
• Slim profile for tight engine compartments and inline filter housings.
• Durable construction for repeated service cycles.
