2007 Honda Accord coupe
Perfect fit for a 2007 accord coupe or sedan. Fixed a noisy power steering pump straight away on a 240,000 mile car. Easy DIY fix

No issues
Great aftermarket o ring. If for whatever reason OEM isn’t possible, these o rings will work perfectly fine. Had no issues installing into power steering system. Still would recommend Honda o rings if you can because they are also cheap.

Fixed noisy and leaking power steering pump
My daughters 2008 Honda Accord 2.4L 4 cylinder that had a very noisy power steering pump which was also starting to leak. I was about to buy a new pump when I found out it might just be leaking from the hoses to the pump. I bought these O rings for the hose connections at the power steering pump, and spent 15 minutes replacing them. Pump is quiet again! The suction hose can develop a leak, letting air get into the pump which creates the loud noises. This fix is all I needed, and was much cheaper and faster than replacing the power steering pump.
