Great quality
These o-rings worked perfectly on a 2010 Honda Odyssey. Stopped all the leaking from the pump. Highly recommended

GARBAGE. Don’t waste your money
Absolute trash. The low pressure o-ring (orange) broke and split and broke in half after less than two hours of installation. Don’t waste your time and money on these cheap Chinese o-rings. The OEM Honda o-rings are literally cheaper and light years ahead of these in quality
