Diagram ref no 2 & 13
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.

OEMatch Heater hoses & pipes — Durability, Sealing, Performance
OEMatch supplies many parts for Porsche heating and cooling systems, including heater hoses and coolant pipes selected for material suitability and model coverage for Porsche vehicles.
Understanding OEMatch Heater hoses & pipes
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original heater hoses & pipes.
OE (Original Equipment) refers to parts matching original specifications for the heater hoses & pipes and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM heater hoses & pipes engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Heater hoses and pipes carry hot coolant from the engine to the heater core and return cooled fluid to the cooling circuit. They maintain coolant flow, support cabin heating, and help prevent air ingress and leaks that can affect engine temperature control.
Benefits Include
- Restores coolant circulation to support cabin heating and engine temperature control
- Reduces the risk of coolant leaks that can lead to overheating
- Materials selected for heat and pressure resistance suitable to Porsche applications
- Replacements that align with original mounting points and connection types
Why Heater hoses & pipes Wear and Fail
- Age-related rubber degradation causing cracking, swelling or hardening
- Corrosion or pinhole defects in metal pipes
- Coolant contamination or chemical breakdown leading to internal deterioration
- Loose, damaged or corroded clamps and fittings allowing leaks
The Importance of Replacing with OEMatch Heater hoses & pipes
Replacing worn heater hoses and pipes restores reliable coolant flow and cabin heating while lowering the chance of coolant loss and engine overheating. Regular inspection and timely replacement helps maintain system pressure integrity and avoids secondary damage to the heater core, water pump or head gasket. Choose components that match your Porsche model and the correct connection types to ensure straightforward installation and ongoing system reliability.
Advantages
- Selected materials for resistance to heat, pressure and corrosion
- Designed to match original dimensions and hose routing where applicable
- Suitable for maintenance, restoration and preventative servicing
Support & Advice
These items can appear straightforward to fit but may require specific procedures such as correct routing, adjustment and securing of hose / pipe ends. If you lack the correct tools or are unsure about hidden fastenings or sensors, seek professional installation.
