Product Description

This EPDM O-ring is black in color, round in cross-section, has a durometer of 70A, and is designed for use in a wide variety of sealing applications.

EPDM is acceptable for temperature applications between -70 degrees F (-57 degrees C) to 300 degrees F (149 degrees C). It is compatible for use with water and steam, silicone oil and grease, polar solvents (alcohols), acids, glycol-based brake fluids, ozone, and weathering. It is vulnerable to many oils, gasoline, and solvents. This material meets ASTM International standards.

This EPDM O-ring has a shore durometer of 70A. Shore durometer is 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, with 100 indicating no indentation.

O-rings commonly 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 sizes, and can be ordered based on required nominal inside diameter (ID), outer diameter (OD), and cross-sectional (CS) diameter.

This EPDM O-ring meets standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings.

Like others, I was shorted in my package of 100. When I saw that someone received 99 I didn't think it was a big deal--it's easy enough to miss 1 o-ring. When my package arrived, I opened it up and took out the 2 that I needed for the job at hand. Then I thought I'd check the count. 88 o-rings! Are you serious!?! Come on, how do you leave out 12% of the quantity and think that that's OK?!

Update: I returned the package of 88 and got a replacement package. This time it was 87!
I then contacted the supplier of the seals (not Amazon). The supplier doesn't do retail, but they have a website and when I contacted them, they informed me that they package by weight and that their scale must have been off for the batch(es) in question. They sent me a new package, this time of 101. They're a stand-up operation with a process that deviated a bit. The o-rings themselves are fine and now I'm satisfied with the experience.

Size: 228Nominal Width: 0.139Overall Width: 0.139Outside Diameter: 2-1/2Inside Diameter: 2.234Nominal Inside Diameter: 2.234Number of Items: 25Nominal Outside Diameter: 2-1/2
Item arrived on-time and in good condition in a sealed plastic bag. Labeling on the bag included general item description (EPDM O-ring black -228), part count and part and stock-keeping numbers, but omitted the size specifications. There was no obvious damage or defects and the part count was correct.

The rubber seem to be of good quality and is firm, smooth and dry, with a light residue of release-agent powder (this is acceptable). It should be noted that the cross-sections of the O-rings are not perfectly round; there is a very slight lip on the inner- and outer-most diameters. This is no doubt where the dies met for the molding process, and is unlikely to interfere with performance. Measurement of about half a dozen or so pieces revealed all actual dimensions (which differ from the nominal dimensions--I highly recommend consulting the "Product Details" section) to be within specified tolerances.

All-in-all, these seem to be fine quality O-rings, though not quite top-of-the-line. Still, for the price I paid at the time (less than $1--Small Parts's prices can fluctuate quite a bit, I recommend checking them frequently), they were an OUTSTANDING value. Recommended.

Not much to say, exactly as described, i.e. it's an o-ring which it's ID/OD are as indicated. Prompt shipment, no damage (had to kill an o-ring in shipment)

Perfect size and durable.
I use these in a hand sprayer of a pressure washer. Lots of pressure and abrasion.
great

I used this size O-Ring as a rubber suspension mount for a motorcycle speedometer, as this is how they were mounted originally from the factory. Works great and now I have a lifetime supply! (minimum order was ten or twelve)

I've ordered two sizes now, and neither has matched this chart here. I've measured and measured like crazy, and I've not received what I've expected. The o-rings seem to be really nice; the fault is surely mine. If you're looking for o-rings, these are the ones to get!

(Can someone explain the sizes of o-rings to me? Amazon Supply (formerly Small Parts) can't. The "Nominal Inside Diameter" column doesn't seem to make sense. I ordered a package of the 008 rings (Nominal ID 3/16") and they weren't right for my project so I ordered a package of the 011 (Nominal ID 5/16") and they were a LOT smaller than the 008s. I thought 3/16" > 5/16" (and Actual ID .301" > .176"), but I seem to be wrong! The reason I don't know exactly what I need is because this is for a craft project so I don't need to be exact, but I need something bigger than the 008 I had. Going up three seemed right. Do I need to go three in the other direction, i.e., to 005? Can you aim me towards an URL which will explain what I need to know? Thanks for helping!)
