Hose Clamp, B29 X 12 X 1.7. 

The Hose Clamp B29 x 12 x 1.7 is a genuine Porsche OEM clamp designed to securely fasten hoses to pipes and fittings across the vehicle’s cooling, heating, and fluid systems. Manufactured to Porsche specifications, it provides consistent clamping force to ensure a tight, leak-free seal and keeps hose connections secure under pressure, heat, and vibration.

Fits:
  • Porsche 970.2 Panamera S V6 Turbo 3.0L 2WD (420Hp) 2014-16
  • Porsche 970.2 Panamera S V6 Turbo 3.0L 2WD Executive 2014-16
  • Porsche 970.2 Panamera 4S V6 Turbo 3.0L 4WD (420Hp) 2014-16
  • Porsche 970.2 Panamera 4S V6 Turbo 3.0L 4WD Executive 2014-16  

Diagram Ref No 27

What This Product Does:

  • Clamps hoses in place so they do not slip off under pressure or vibration.
  • Applies even pressure around the hose end to create a tight, leak-free seal.
  • Helps maintain system pressure and reliability in coolant, heater, vacuum, and other fluid hose circuits.

Symptoms Of Wear Or Failure:

  • A weakened clamp may allow coolant or fluid to seep from the joint, often leaving wet staining or dried residue.
  • If the clamp loses tension, the hose may shift or partially slip off the fitting under pressure.
  • The clamp may become stretched, stripped, or deformed, preventing it from holding the hose securely.
  • Rust weakens the clamp material and reduces clamping force, increasing the risk of leaks.
  • A damaged band can apply uneven pressure, causing an unreliable seal and possible leakage.
  • If used on coolant/heater hoses, clamp failure may contribute to low coolant level, overheating, reduced heater performance.


Why Replacement Matters:

  • Prevents coolant or fluid leaks by maintaining a tight, secure seal at the hose connection.
  • Keeps hoses firmly attached, reducing the risk of hoses slipping off under pressure or vibration.
  • Maintains correct system pressure, which is essential for proper cooling, heating, and fluid circulation.
  • Helps avoid secondary damage, as leaking coolant or fluids can harm nearby components, sensors, and wiring.
  • Ensures long-term reliability, especially in high-heat engine bay environments where clamps fatigue over time.

About Hose Clips / Screws / Brackets and Fixings

Coolant Hose Clips, Screws, Brackets & Fixings – Secure Connections for Porsche Cooling Systems

Coolant hose clips, screws, brackets, and fixings are small but crucial components that ensure the stability, sealing, and reliability of your Porsche’s cooling system. These precision-engineered fittings keep coolant hoses and pipes securely fastened, maintaining proper coolant flow and preventing leaks — even under extreme temperature and pressure conditions.

At Design911, we stock a complete selection of genuine and manufacturer-quality coolant hose clips, screws, brackets, and fixings for Porsche 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each component is engineered for exact fitment, corrosion resistance, and long-term strength — ensuring every hose and connection performs to factory standards.

What Do Coolant Hose Clips and Fixings Do?

These parts form the structural foundation of your Porsche’s cooling system. Their primary functions include:

  • Securing coolant hoses and pipes in place to prevent movement or detachment.
  • Maintaining tight, leak-free connections under varying thermal pressures.
  • Supporting cooling system alignment through brackets and clips.
  • Protecting hoses from vibration damage or contact with moving components.

Together, these fasteners help ensure reliable coolant circulation and stable engine temperatures — vital for your Porsche’s performance and longevity.

Why Do Clips, Screws, and Fixings Fail?

Even the smallest cooling system parts are exposed to significant wear over time. Common causes of failure include:

  • Corrosion or rust from heat and coolant exposure.
  • Metal fatigue or cracking under repeated thermal expansion.
  • Loss of tension in hose clamps, leading to leaks.
  • Plastic degradation on older or high-mileage vehicles.
  • Vibration damage loosening brackets or screws.

Symptoms of failure include coolant leaks, rattling noises in the engine bay, or hoses slipping from their fittings.

Why Replace Faulty Coolant Hose Fixings?

Replacing worn or corroded clips and brackets is essential to maintain cooling efficiency and prevent costly engine damage from leaks or overheating.

Benefits of replacement include:

  • Restored, secure hose and pipe connections.
  • Prevention of coolant leaks and pressure loss.
  • Improved cooling system integrity and safety.
  • Manufacturer-quality construction for long-lasting performance.

All components in this range are made from high-grade materials — including stainless steel and reinforced polymers — designed to exact specifications for strength, corrosion resistance, and precision fitment.
