Turbo Intercooler Hose Pipe Tube 9678431780 for Peugeot

Product Overview

Turbo Intercooler Hose Pipe Tube 9678431780 for Peugeot covers the charge air circuit on Peugeot applications. The reference set on file is OEM 9678431780, which is the figure to quote when you send an enquiry. This part carries pressurised charge air between the turbocharger, the intercooler and the inlet manifold. The failure modes that bring it across a parts counter are split necks next to the quick-connect collar and delamination where charge air temperature peaks, reported as boost loss under load, limp mode and a measurable drop in charge pressure. We hold it as part of a cooling-system range of more than 4000 types built for the independent aftermarket in Europe, the Middle East and South America.

Key Benefits

• Ordered by reference not by photo — The listing carries OEM 9678431780. You quote the number, we confirm against the same number, and the part that ships is the one on the invoice.
• Mixed pallets instead of single lines — A cooling-system range of more than 4000 types means a slow-moving line can travel with fast movers instead of being ordered on its own.
• Tooling route for obsolete references — Where the reference is out of production, we develop the mould from the sample you supply rather than turning the enquiry away.
• Checked on the features that matter — Inspection concentrates on the cuff diameters, the bend angle and the clamp or quick-connect style at each end — the dimensions that put a part back in the box if they are wrong.

Application Scenarios

Scheduled cooling-system overhaul

The vehicle is in for a coolant leak and the workshop replaces the whole branch at once rather than chasing the next failure in a month. On this reference that means quoting 9678431780 with the quantity and letting the packing follow.

Warranty-expired fleet maintenance

A fleet past dealer coverage moves to independent supply and needs the same reference coverage at a working price. On this reference that means quoting 9678431780 with the quantity and letting the packing follow.

Counter stock for a busy platform

Peugeot volume in the region justifies holding the line on the shelf instead of ordering it in per job. With 9678431780 on the list the rest of the charge air circuit can be priced at the same time.

Who It Is For

• Workshop and fast-fit chains — replacing turbo and intercooler hoses on Peugeot daily and judging a supplier on whether the part fits first time. For them 9678431780 is a line on a shelf, not a project.
• Online parts sellers — listing by OEM reference, where a mismatched number turns into a return and a negative rating. They order 9678431780 by the carton and reorder against the same number.
• Fleet and bus operators — running Peugeot vehicles past warranty and buying cooling-system parts by the box to keep downtime short. For them 9678431780 is a line on a shelf, not a project.

Problems It Solves

Unclear compound

PA66 mouldings crack rather than weep, so a hairline split can empty a coolant system quickly once it opens. For Peugeot buyers it is the difference between a stocked line and a credit note on 9678431780.

Reference mismatch

Visually identical parts carry different connector geometry between model years. Quoting OEM 9678431780 fixes the identity before money moves. With 9678431780 the check is the cuff diameters, the bend angle and the clamp or quick-connect style at each end, and it happens before despatch.

Split ordering

Sourcing one hose from one supplier and the matching flange from another doubles the freight and the paperwork for the same repair. With 9678431780 the check is the cuff diameters, the bend angle and the clamp or quick-connect style at each end, and it happens before despatch.

Technical Features

The part serves the charge air circuit and carries pressurised charge air between the turbocharger, the intercooler and the inlet manifold. It is moulded in PA66 glass-filled nylon, chosen because glass-filled PA66 gives a rigid pipe that holds its shape against vibration and keeps clamp faces dimensionally stable at under-bonnet temperature.

Used where the part must hold a fixed geometry and carry bolted or clipped interfaces. PA66 mouldings crack rather than weep, so a hairline split can empty a coolant system quickly once it opens.

Values marked TBC are not stated on the source catalogue. They are confirmed in writing on the quotation rather than estimated here.

Comparison With the Alternatives

Use Guide

1. Confirm the reference

   Match OEM 9678431780 against the number on the part you removed. Do not match on outline alone.

2. Check the interfaces

   Compare the cuff diameters, the bend angle and the clamp or quick-connect style at each end before the vehicle is stripped further.

3. Inspect on arrival

   Look for transit damage on sealing faces and connectors. PA66 mouldings crack rather than weep, so a hairline split can empty a coolant system quickly once it opens.

4. Fit with the original clamp style

   Reuse the clamp type the Peugeot platform was designed around, and fit any seal or O-ring supplied with 9678431780 rather than carrying the old one over.

5. Pressure check before handover

   Refill, bleed the circuit and check for blown cuffs at clamp joints at working temperature before the vehicle leaves.
