Product Information
Product Information
Heating tube inside sill (left/right).
This Heater Tube Inside Sill is a Genuine Porsche OE component designed to route heated air through the inner sill section of classic air-cooled Porsche 911 models from 1969 to 1989. The heater tube carries warm air produced by the engine’s heat exchangers through the sill cavity toward the cabin ventilation system.

Fits:
Porsche 911 1969 - 1989

Diagram ref no 15

Function: Installed inside the vehicle’s sill structure, the tube forms a critical part of the classic 911 heating system. It channels heated air forward into the cabin ducting, supporting effective interior heating, windscreen demisting, and overall comfort in cooler conditions.

Over time, original heater tubes can degrade due to heat cycles, age, and corrosion, resulting in reduced airflow or heat loss before reaching the cabin. In severe cases, damaged ducting may allow unwanted fumes or debris into the heating system. Replacing the tube with a Genuine Porsche part restores factory heating efficiency, preserves originality, and ensures long-term reliability of the heating system.

Replace this heater tube if you notice:
Weak or uneven heater output
  Cracked, brittle, or collapsed ducting
  Heat loss before air reaches the cabin
  Unpleasant odours from the heating system
  During restoration or refurbishment of the sill or heating system

Product Information
Heating tube inside sill, Ø55 mm, length 685 mm.
This heating tube inside sill is a high-quality replacement air-duct tube designed to channel warm air from the exhaust-heated heating system through the sill area of classic Porsche 911 models built from 1969 through 1989 and 356 B/C models. It matches the original part’s fit and performance to maintain proper heating airflow in your vehicle’s cabin.

Fits:
Porsche 356 B/C 1.6 01/1959 - 12/1965
Porsche 911 2.0-3.3 08/1968 - 07/1989
Porsche 912 1.6 01/1965 - 02/1970
Porsche 914 1.7-2.0 01/1969 - 07/1974

Diagram ref no 15

The heating tube directs hot air generated by the engine’s exhaust-heated heat exchangers into the cabin area via the sill ducting. This ensures your classic Porsche’s heater system distributes warmth effectively, improving defogging, defrosting, and passenger comfort in cooler weather.

Function: Installed along the inner sill section, this tube captures heat from the heater system and delivers it through the duct network into the footwell or cabin air distribution points. A properly functioning heater tube helps maintain consistent cabin temperature and prevents heat loss due to damage or age-related degradation of the original ducting.

Over decades of use, original heater tubes can become cracked, brittle, or collapsed, leading to poor airflow, heat loss, or even exhaust gas intrusion into the cabin air system. Replacing the deteriorated tube with an OE Match unit restores effective hot-air distribution, improves cabin comfort and heater efficiency, and keeps the vintage heating system functioning as intended.

Replace this heating tube when you notice:
•  Weak or inconsistent warm air delivery from the heater
  Deteriorated, cracked, or collapsed heater tubing
  Excessive heat loss before reaching the cabin
  Unusual smells from heater ducts (possible leaks)
  During full heater system or sill restoration work

About Heater hoses & pipes

Porsche Heater Hoses & Pipes | Reliable Coolant Flow & Cabin Heating Efficiency

Heater hoses and pipes are essential components in your Porsche’s heating and cooling system. They carry heated coolant from the engine to the heater core, enabling warm air circulation throughout the cabin. Without properly functioning hoses and pipes, the heating system cannot deliver consistent temperature control or maintain efficient engine cooling.

At Design911, we supply premium heater hoses and coolant pipes that meet or exceed original engineering standards. Constructed from high-quality rubber, aluminium, or reinforced composite materials, these components ensure leak-free performance, excellent heat resistance, and long-term durability.

Whether you’re restoring a classic 911 or maintaining a modern Porsche with advanced climate control systems, our heater hoses and pipes provide the precision, fitment, and performance required for dependable heating and cooling.

What Do Heater Hoses & Pipes Do?

Heater hoses and pipes form the circulation path that carries hot coolant from the engine to the heater core, allowing the HVAC system to provide warm air inside the cabin.

Core Functions:

  • Transfer heated coolant to the heater core for cabin warming.
  • Maintain proper coolant flow between engine and heating system.
  • Regulate temperature and prevent air pockets in the system.
  • Ensure efficient heat exchange for passenger comfort.
  • Protect against coolant loss and overheating.

A properly functioning set of hoses and pipes is critical for both engine cooling performance and interior heating efficiency.

Why Do Heater Hoses & Pipes Fail or Degrade?

These components endure constant heat, pressure, and vibration. Over time, material fatigue and corrosion can lead to leaks or blockages.

Common Causes of Failure Include:

  • Age-related cracking, swelling, or brittleness of rubber hoses.
  • Corrosion or pinhole leaks in metal pipes.
  • Coolant contamination or chemical degradation.
  • Loose or damaged hose clamps causing leaks.
  • Blockages from scale or debris restricting coolant flow.

When heater hoses or pipes fail, symptoms include coolant leaks, weak cabin heat, overheating, or a sweet smell of antifreeze inside the cabin.

Why Replace Your Porsche Heater Hoses & Pipes?

Replacing worn or damaged heater hoses and pipes restores proper coolant circulation, prevents leaks, and ensures stable heating and engine temperature control.

Key Benefits:

  • Restores efficient coolant flow and cabin heating performance.
  • Prevents leaks, overheating, and engine damage.
  • Improves reliability and system pressure integrity.
  • Resistant to heat, pressure, and corrosion for long lifespan.
  • Direct-fit replacements for Porsche 911, Cayman, Boxster, Panamera, Macan, and Cayenne models.
  • Ideal for maintenance, restorations, or performance upgrades.

It’s recommended to replace heater hoses and clamps during coolant service intervals to maintain maximum system reliability.

Highlights

  • Precision-engineered Porsche heater hoses and coolant pipes.
  • Constructed from high-quality, heat-resistant materials.
  • Direct-fit replacements for Porsche models old and new.
  • Designed for long-term resistance to pressure and corrosion.
  • Ensures reliable heating and engine cooling performance.
  • Ideal for restoration, servicing, and preventative maintenance.
