Description

Volvo Penta 125362 is a genuine OEM O-ring used in Volvo Penta marine cooling-system service. Volvo Penta’s official parts shop lists 125362 as an active genuine O-ring, and current reviewed dealer references identify it more specifically as a heat exchanger O-ring, making it best presented as a cooling-system sealing O-ring where exact part-number matching matters. Current reviewed public sources do not publish a confirmed diameter or cross-section specification for this exact OEM number.

Key Features

• Genuine Volvo Penta OEM part number 125362.
• Identified in current reviewed dealer references as an O-ring for heat exchanger service.
• Individual sealing part sold separately rather than as a larger kit.
• Current reviewed dealer listings show approximate product weight around 0.010 kg / 0.02 lb.

Engine Compatibility
Current public references confirm the OEM number clearly, but the strongest reviewed functional description identifies 125362 as a heat exchanger O-ring rather than publishing a broad official engine list. Fitment should be confirmed by exact engine serial number and by matching the original heat exchanger sealing point before ordering.

Serial Number Fitment Notice
O-rings can vary by inside diameter, cross-section, material, and sealing-groove design. Confirm Volvo Penta 125362 by engine serial number and by matching the original O-ring location before ordering. Volvo Penta continues to list 125362 as an active genuine part number.

When This Part Needs Replacement
Replace this O-ring whenever the related heat exchanger component is removed for service, or when the original seal shows flattening, hardening, cracking, seepage, or loss of sealing tension. Because current reviewed references identify 125362 as a heat exchanger O-ring, renewing it during cooling-system disassembly is the right service practice for dependable reassembly.

Installation Notes
Install only on clean sealing surfaces and compare the new O-ring directly to the original before final assembly. Since current public references confirm the part number more clearly than they publish full dimensional data, serial-number verification and direct comparison to the removed seal are the safest checkpoints before installation.

Alternate/Superseded Part Numbers
Current reviewed public sources clearly identify 125362 as the active Volvo Penta number for this O-ring. No confirmed newer Volvo Penta supersession is clearly shown in the reviewed current references.

Parts Desk Insight
For small cooling-system seals like 125362, the strongest buying checkpoint is the exact heat exchanger sealing location, not appearance alone. Current reviewed sources point most clearly to heat exchanger use, so matching the original seal location and confirming by serial number is the cleanest way to avoid ordering the wrong O-ring.
