Product Description

This O-ring is made of black Viton and has a durometer of 90A, a round cross-section, and can be used across a wide temperature range (-15 degrees F /-26 degrees C to 400 degrees F/ 205 degrees C). Designed for use in a wide variety of sealing applications, this Viton O-ring meets standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings.

Viton (fluorocarbon elastomer) has heat, fuel, and chemical resistance and is compatible for use with non-flammable hydraulic fuels, silicone oil, chlorinated hydrocarbons (trichlorethylene), fuels, aromatic hydrocarbons (benzene) and aliphatic hydrocarbons (propane), as well as high vacuum environments, ozone, and weathering. Viton is vulnerable to low molecular organic acids, ammonia gas, alkalis, amines, glycol-based brake fluids, and super-heated steam.

The durometer hardness of this Viton O-ring is 90A. Durometers measure the hardness of a material and its resistance to permanent indentation. A higher durometer value indicates greater resistance to indentation. On a scale of 0 to 100, a value of 0 indicates that a sample was completely penetrated, while a value of 100 shows no indentation in the sample. The letter following the number identifies the shore scale, which is either shore A or D. Shore A is used for softer plastics, while shore D is used for harder plastics.

O-rings provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly seen in engines, faucets, flanges, valves, and various cylinders. They are circular in shape, with a round cross section, and a hole in the center, similar to a doughnut. O-rings are available in various AS568A dash sizes, which is the standardized sizing for O-rings, and defines the nominal inside diameter (ID), outer diameter (OD), and cross-sectional (CS) diameter of an O-ring.

I have been having a problem with oil leaking from the crank angle sensor (CAS)and got the recommended size o-ring however I believe the o-ring was too soft. Fast forward 6 months and I know Viton O-rings are a lot more expensive then Buna material but this one should last a life time in the car since it operating temperature is well withing Viton's abilities. Since this is a lot harder then a 70A or 75A durometer o-ring it was extremely difficult putting the CAS back on but it has been a month and I am proud to say this o-ring is holding up wonderfully and I have a lot of spares (broke one since we were having a hard time with the install).

I bought these to re-seal the running light housings on my motorcycle. They have stood up to the heat the halogens produce and they have not become brittle in the sun of California!!

I got these to replace the Kohler sink drain basket o-rings which wear out over time.
Home Depot did not have these in stock but these from Amazon work perfectly and are pretty cheap.

Hard durometer was needed plus the material was exactly as specified for the chemical it was to be subjected to, its still there holding up.

I know these are for more serious sealing operations, but I used them as Air Cleaner hold downs on my 1971 Mercedes and they worked great!

I lost one of my O rings during a cleaning some time ago and could not get a replacement so online I went in search of a new one and I found a massive selection from this vender. You have to know the exact size that you are looking for and I ordered one that could have been a bit smaller but this one actually stayed in place better because it was a little larger than the original so it's all good now and I have a few on hand for when I lose them from my other fountains.
