Product Information
Hose Clamp, B27 X 12.

The Hose Clamp B27 x 12 is a genuine Porsche OEM clamp designed to securely fasten hoses to pipes and fittings throughout the vehicle’s cooling, heating, and fluid systems. Manufactured to Porsche specifications, it ensures a tight, reliable seal to prevent leaks 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

What This Product Does:

  • Clamps hoses in place to prevent them from slipping off under pressure or vibration.
  • Creates a tight seal between the hose and the connection point to prevent fluid or air leaks.
  • Helps maintain correct pressure and reliability in systems such as coolant hoses, heater hoses, and other fluid circuits.

Symptoms Of Wear Or Failure:

  • Coolant, power steering fluid, or other fluids may seep from the hose joint if the clamp loses tension.
  • A weakened clamp may allow the hose to move or partially slide off the fitting, especially under pressure.
  • If the clamp is stretched, damaged, or worn, it may not clamp evenly even after tightening.
  • Corrosion reduces the clamp’s strength and can lead to sudden failure, especially in high-heat or damp engine bay conditions.
  • A damaged clamp band may apply uneven pressure, causing leaks or an insecure hose connection.
  • Leaks caused by a failing clamp can result in low coolant level, weak cabin heating, engine overheating

Why Replacement Matters:

  • Prevents fluid leaks by maintaining a tight seal at the hose connection.
  • Reduces risk of overheating, since coolant leaks often start at hose clamp joints.
  • Keeps hoses securely attached, preventing them from slipping off under vibration or system pressure.
  • Maintains correct system pressure, which is essential for cooling and heating performance.
  • Protects surrounding components, since leaking coolant or fluid can damage nearby parts over time.
