What This Product Does

The connector joins vacuum pipework at the relevant connection point. Its role is to maintain the connection rather than generate vacuum or operate an actuator.

Functions

  • Connects sections of vacuum pipework.
  • Provides a replacement for a damaged or leaking connection.
  • Supports continuity of the connected vacuum circuit.

Technical Details

  • Brand: OE Match.
  • 9P1129487 is identified as a distributing piece and moulded hose in the 911 Carrera diagrams.
  • 911 Carrera L-Jetronic II applications: 930.20/21/26, 1984–86; 930.20/25/26, 1987–89. Air-injection diagrams also identify 930.26, including AUS, CH and S applications for 1984–86.
  • 92857471705 is identified as a protective tube in the supplied 964 and 993 diagrams.
  • 964 diagram applications: M64.01/02/03, 1989–94; 964 Turbo M30.69 and M64.50, 1991–94.
  • 993 Carrera/4 diagram applications: M64.05/06/07/08, 1994–98. Diagram quantities vary by application and position; they do not establish the quantity supplied.

Symptoms of Fault

  • Visible cracks or deterioration around the connection.
  • Hissing near the vacuum pipe joint.
  • Leakage identified during vacuum testing.
  • Irregular operation of the connected vacuum-controlled component.
  • Unstable idle where the leaking circuit affects the intake system.

Why Replacement Matters

A leaking connection can interrupt vacuum supply to the attached circuit. Renewing a confirmed faulty connector addresses that leak point; adjoining hoses and fittings should also be inspected for deterioration. OE Match develops replacement components around Porsche applications, using original references and application information to guide component selection.

FAQs

Does this replace a vacuum pump or actuator?
No. It is a pipework connector, not a pump, valve or actuator assembly.

Should nearby hoses be inspected?
Yes. Hardened or split hoses can leave the circuit leaking after the connector has been renewed.

Is the same connector used throughout every listed vehicle?
The installation position depends on the application. Compare the original connection and relevant diagram before fitting.

Product Information
Product Information

OE Match water drain sleeve hose clamp for classic Porsche 911 applications, including the specified 930 Turbo models. 

Fits

  • Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
  • Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
  • Porsche 911 1978-1983 3.0L / SC
  • Porsche 911 1984-1986 3.2L
  • Porsche 911 1975-1977 3.0L Turbo (930)

Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

The clamp retains the water drain sleeve at its connection within the ventilation assembly. It is retaining hardware for the drainage connection, rather than a heater coolant hose, blower or fresh-air housing.

Functions

  • Holds the drain sleeve at its attachment point.
  • Supports reassembly of the ventilation drainage connection during repair or restoration.

Technical Details

  • Product identification: 99951214502.
  • Brand: OE Match.
  • Component: hose clamp for the water drain sleeve.
  • Assembly context: ventilation and heating system.
  • Diagram position varies with model and production period.

Symptoms of Fault

Inspect the clamp if the sleeve is loose or there is seepage around its connection. Check the sleeve and adjoining fitting too: damage to either can require attention independently of the clamp.

Why Replacement Matters

A damaged or corroded clamp may no longer retain the sleeve correctly. Renewing defective retaining hardware allows the connection to be secured during reassembly. OE Match focuses on Porsche replacement applications, with specification checks and sample evaluation forming part of its development process.

FAQs

Should a corroded clamp be renewed?
Replace it if corrosion or damage prevents correct fastening. Inspect the adjoining sleeve before reassembly.

How should compatibility be checked?
Compare part number 99951214502 with the original component and confirm the vehicle application. The diagram references identify different positions for this clamp across the listed assemblies.

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.
