I ordered these with next-day shipping so I could repair a vacuum leak in my 2004 Mercury Grand Marquis EATC (electronic automatic temperature control) unit. There is a common problem where the rubber o-rings will fail, causing a vacuum leak and letting all of the air blow out the defrost vent regardless of the setting. These are the same as the silicone o-rings others use to fix the problem, except that fluorosilicone is more chemical resistant. I don't car about that, but I do care that these were avaialble in a pack of 25, while the silicone was only available in a pack of 100. Since I only need 4, this was a good deal.

The item arrived quickly, as promised (I really like dealing with Small Parts, Inc), and they work very well for what I needed.

The dealership's only option is to replace the EATC, which is a >$600 part. For about an hour of my time and around ten bucks shipped (next-day w/ Amazon Prime) for these o-rings, I got an incredible deal. :) They'll fix the same problem (air only comes out defrost vent) on a lot of vehicles, since Ford used the same basic controller in the Explorer, F-150, Crown Vic, Grand Marquis, Marauder, and probably a few other cars for several years.

Fluorosilicone O-Rings size 202

I purchased these for my 3-bar MAP sensors and to keep them on hand in case the original Viton O-rings failed. So far the fluorosilicone o-rings are handling 27 psi of boost without any problems.

Viton is popular because it is abrasion resistant and relatively strong, and has a high operating temperature range. However, Viton generally does not perform well below -20F and they tend to take a set in high temperature applications. Silicone has a much wider temperature range but it isn't as resilient against a lot of fuels and oils, and isn't abrasion/tear resistant - although Ford uses them for the anti-drain back valve on their engine oil filters.

Fluorosilicone combines the properties of Viton with silicone to give it outstanding cold temperature performance down to -100F and up to +350F, while being resilient against most automotive fuels and oils which happens to be the environment of the MAP sensors. I read that many fuel injectors use fluorosilicone o-rings as well, which makes sense given their application.

These were sized properly with minor variances in the outer diameter.

Overall: 5/5 stars

So far this ring, being used to drive a key copying machine, has worked well though I got this particular type for the cold weather capabilities claimed, for use in my truck. The weather has not yet been extremely cold yet so we will see how well it performs then.

Replacing orings on fuel cap. These are more durable than the ones in place. I like them. Glad you had these in stock.
