I was troubleshooting a coolant leak in my 99 Silverado 5.3L V8. I had no visible leaks. I replaced the water pump gaskets and decided to replace the thermostat O-ring at the same time. My water pump and thermostat are the "old style". I don't know if this one fits the new style but it was a perfect fit for my application. I am pleased to say I no longer have a coolant leak either. Fel-Pro makes good o-rings and gaskets. I wouldn't hesitate to use their brand in just about any application. I did go with AC Delco OEM water pump gaskets though. The cheaper fel-pro ones were felt and the equal to OEM metal ones were 3 dollars more each than the OEMs. Most of the time, fel-pro is the better deal though.

The O-ring was made well and it is sealing good so far.

This o ring is perfect for oil filter cover on a Z 125 Pro. Other sites want big money for the same thing!

Exactly what I needed to seal things back up. The OEM gasket was pinched during an inspection prior to installing the 5.3 LM7 engine into a 1960 Impala, this (along with being more careful about seating the gasket) got me back up and running quickly.

Perfect fit with the correct "O" ring material for hot water (nitrile).

This is the product to have right here, nothing on amazon beats this thing come on look at it! There is nothing flawed with its design, and the execution of display is something the Olympics should take notes from. Ok I reached the min text required, its an Oring it works.
