Because this elbow appears across multiple oil cooler and oil filter adapter diagrams, the exact parts diagram should be confirmed before ordering.
Serial Number Fitment Notice
Verify fitment by exact engine serial number and the correct Mercury MerCruiser oil cooler / oil filter adapter / flywheel housing parts diagram before ordering. Oil hose elbows can vary by angle, thread, hose routing, and service location, so the correct match is the diagram callout rather than engine size alone.
When This Part Needs Replacement
Replace this elbow when the original is corroded, cracked, leaking, seized, damaged during hose removal, or no longer provides a secure oil hose connection. It should also be inspected during oil cooler, oil filter adapter, flywheel housing, or oil hose service if there are signs of leakage or hose misalignment.
Installation Notes
Install 48872 / 22-48872 only after confirming the correct diagram location. Inspect the oil hose, clamps, adapter fitting, oil cooler, and surrounding hardware before reassembly. Use the correct sealing method where specified and avoid overtightening into cast housings or adapters.

Parts Desk Insight
The easy mistake with this elbow is treating it like a generic 45-degree fitting. On MerCruiser oil cooler systems, the correct fitting depends on the oil hose routing, adapter location, and parts diagram, so matching the serial-number-based diagram is the safest way to avoid leaks or poor hose alignment.
