Genuine Volvo Penta 860127 is a heat exchanger sealing strip used in the cooling system on a wide range of Volvo Penta 31-, 32-, 41-, 42-, 43-, 44-, and 300-series marine diesel engines. Parts diagrams place 860127 at the heat exchanger end-cap and housing interface, where it provides sealing within the exchanger assembly. Some heat exchanger configurations require up to three sealing strips — confirm the quantity required for your specific assembly from the applicable Volvo Penta parts diagram.

When to Replace
- Whenever the heat exchanger is disassembled for service — sealing strips should not be reused
- When the strip is flattened, hardened, cracked, or distorted
- When coolant or seawater leakage is present around the exchanger end-cap
- When the strip no longer seats evenly in its groove
- When corrosion or age has visibly compromised the sealing surface
Service Interval
Inspect the heat exchanger sealing components during annual cooling system service or whenever the exchanger is opened for cleaning or core inspection. Replace 860127 any time the heat exchanger end-cap is removed — a reused strip may not reseal reliably and can allow coolant or seawater cross-contamination.
Installation Notes
- Clean the sealing groove and all mating surfaces thoroughly before installing the new strip
- Inspect related O-rings (including 925027), gaskets (including 964106), end caps, and exchanger core surfaces while the assembly is apart
- Where the parts diagram specifies multiple 860127 strips, replace all required strips and confirm correct orientation before reassembly
- Do not reuse old sealing strips — even strips that appear undamaged may not reseal correctly after compression
Technical FAQ
How many sealing strips does my heat exchanger need?
Quantity varies by heat exchanger configuration. Some assemblies require up to three 860127 strips. Check the Volvo Penta parts diagram for your specific engine model and heat exchanger assembly to confirm the correct quantity before ordering.
Is 860127 a generic rubber strip or a specific OEM part?
860127 is cataloged specifically as a Volvo Penta OEM heat exchanger sealing strip for the end-cap and housing interface. It is not interchangeable with generic rubber seals — the profile and dimensions are specific to the applicable Volvo Penta heat exchanger design.
What other parts should I replace at the same time?
When servicing the heat exchanger, inspect and replace O-ring 925027, gasket 964106, and any associated end-cap hardware at the same time. Replacing all sealing components together during the same service avoids reopening the assembly for a single worn item shortly after.
Parts Desk Insights
860127 covers an unusually wide range of Volvo Penta engine families — from compact 31-series diesels through the high-performance KAD300 — which means it comes up frequently across different customer enquiries. The most common ordering mistake is not confirming quantity: some customers order one strip and find the diagram calls for three. Always check the specific heat exchanger diagram with the customer before processing the order. It is also worth noting that the strip is inexpensive relative to the labour involved in opening the heat exchanger, so ordering the full quantity required — plus associated O-rings and gaskets — at the same time is the right call for any service job.
