What This Product Does:

  • Clamps the hose in place so it cannot slip off under pressure or vibration.
  • Creates a tight seal between the hose and the fitting to prevent coolant or fluid leaks.
  • Helps maintain proper cooling system pressure, especially on smaller hoses such as vent or reservoir lines.


Symptoms Of Wear Or Failure:

  • A weakened clamp may allow coolant or fluid to seep from the joint, often leaving residue or dampness.
  • If the clamp loses tension, the hose may move or partially slip off the fitting, especially under pressure.
  • The clamp may be stretched, stripped, or deformed and unable to hold the hose securely.
  • Rust weakens the clamp material, reducing clamping force and increasing the risk of failure.
  • A distorted band can apply uneven pressure, leading to leaks or an unreliable seal.
  • If used on coolant hoses, clamp failure can contribute to low coolant level, pressure loss, overheating.


Why Replacement Matters:

  • Prevents leaks by maintaining a tight seal at the hose connection.
  • Keeps hoses securely attached, reducing the risk of hoses slipping off under pressure or vibration.
  • Maintains correct system pressure, which is essential for proper cooling and heating system performance.
  • Helps prevent overheating, since coolant leaks often start at hose clamp joints.
  • Protects nearby components, as leaking coolant can damage hoses, wiring, sensors, and surrounding parts.

Diagram Ref No 9

What This Product Does:

  • Clamps hoses in place to prevent them slipping off due to pressure or vibration.
  • Creates a tight seal between the hose and the fitting to prevent leaks of coolant, air, or other fluids.
  • Helps maintain proper pressure and reliability in systems such as cooling, heating, and vacuum/air hose circuits.


Symptoms Of Wear Or Failure:

  • Coolant, air, or vacuum leaks may appear at the joint if the clamp loses clamping force.
  • A weakened clamp may allow the hose to move or partially slide off the fitting, especially under pressure or vibration.
  • The clamp may be stretched, stripped, or distorted, preventing it from holding tension even when tightened.
  • Corrosion weakens the metal band and reduces clamping force, increasing the risk of failure.
  • A damaged band may apply uneven pressure around the hose, leading to leaks or an insecure fit.
  • If used on cooling or vacuum hoses, clamp failure can contribute to coolant loss, weak heater performance, vacuum or airflow issues.


Why Replacement Matters:

  • Prevents leaks of coolant, air, or vacuum at hose connections by maintaining proper clamping force.
  • Keeps hoses from slipping off fittings, especially under pressure, heat, and engine vibration.
  • Maintains correct system performance, whether the clamp is used in cooling, heating, air, or vacuum circuits.
  • Helps avoid secondary damage, as leaking coolant or air can affect sensors, hoses, and nearby components.
  • Ensures long-term reliability, since clamps weaken over time due to corrosion, heat cycles, and metal fatigue.

  • Creates a tight seal between the hose and the connection point to prevent fluid or air leaks.
  • Maintains proper system pressure, especially in coolant, heater, and other fluid or vacuum hose circuits.


Symptoms Of Wear Or Failure:

  • Coolant or other fluid may seep from the hose connection if the clamp loses tension.
  • A weak clamp may allow the hose to move or partially slide off the fitting.
  • The clamp may become stretched, stripped, or deformed, preventing it from holding the hose securely.

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.
