Perfect fit, solved steering pump noise
Installed this o-ring kit on a 2009 Honda Odyssey. The steering pump was making noise and you could see bubbles in the fluid revivor when the engine was idling indicating a potential air leak from where the hoses attach to the pump. The most difficult part was finding the right 10mm wrench that would allow me to access the lower hose mounting bolt without removing the belt or pump pulley. I wound up taking an old wrench, heated it with a torch, and bent it in a vice to get the right fit. I did order a ratcheting, flex head wrench but while waiting for it to be delivered I was able to make something work. Overall, the o-ring kit worked great, the o-rings seem high quality and this fixed my issue. If you don't already have some, make sure to order the power steering fluid required for Asian/Honda vehicles when you order these o-rings.

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.
