Hose Clamp, B15 X 12. Porsche 970 Panamera 3.6L / 4.8L 2010-16  ❭  99951265109

Hose Clamp, B15 X 12. 
The Hose Clamp B15 x 12 is a genuine Porsche OEM clamp designed to securely fasten small-diameter hoses to pipes and fittings within the vehicle’s cooling and fluid systems. Manufactured to Porsche specifications, it applies consistent clamping force to create a tight, leak-free seal and keep hoses firmly in place under pressure, heat, and vibration.

• 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.

• 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.

• 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.
