TPS Sensor O-Ring Seals
Does anyone know what the part number is for the TPS Sensor O-Ring Seals for a '99 C5? The reason I ask is I need to replace one as it was leaking air out of the tire valve hole in the wheel after spraying it with some Joy dish detergent and water. Broke the bead on my right rear tire with my Tire Machine, took the TPS Sensor out and saw there wasn't a o-ring left to look it as it must of disintegrated. A friend of mine gave me a plastic bag package of GM seals that he is pretty sure are the ones I need. There are 4 in the bag with a stapled receipt from a Chevrolet Dealer showing Part #10268438 Washer 5.890 purchased in 2005. Don't know what the number 5.890 means placed a few spaces away. I am guessing it is the actual size of the O-Ring. On the plastic bag it shows 1026-8438 (Washer Low Tir) then GM#10268438 once again.
One other question if anyone knows. Is one suppose to use some type of lubricant on the O-Ring Seal for the TPS other then maybe some soapy water to slide it on? Just curious being I was always told that a little white grease on O-Rings depending on where they are being used makes them last longer.

Still would like to know if a lubricant should be used on the TPS O-Ring of some type if anyone knows.

Replaced the O-Ring to the TPS Sensor with one of the Chevrolet 0-Rings given to me as I stated in a prior post. Funny they didn't look like anything special and I am sure I could of matched one up with one in a O-Ring Assortment Kit that I happen to have on hand. My friend paid the Dealer over $11 for the (4) Factory O-Ring seals back in 2005. Can't blame anyone for using a #9 O-Ring from your nearest hardware store if it does the trick at a dime each.
