Product Description

  • Metric O-ring made of Viton (fluorocarbon elastomer) for use with a variety of chemicals and fuels
  • Durometer (hardness) of 75A for resistance to penetration
  • Round cross-section provides a seal between cylindrical overlapping surfaces
  • For use across a wide temperature range from -15 degrees F/-26 degrees C to 400 degrees F/205 degrees C
  • Meets standards defined by Aerospace Standard AS568A
Additional Information

This metric O-ring is made of black Viton and has a durometer of 75A, 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), aromatic hydrocarbons (benzene) and aliphatic hydrocarbons (propane). It works well in high vacuum environments and 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 75A. 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.

Not finding the exact replacement O-Rings for the Harbor Freight Hose Reel, this 2.5mm (thick) by 11mm (ID), totaling 16mm was the closest to meeting the OEM specification of 2.4mm (thick) by 11.2mm (ID). The difference between these is, the Viton ring has a .2mm smaller ID, but the actual ring thickness makes up for that. In the end, there is a slightly tighter seal perhaps due to a little stretching of the smaller 11mm ID and then the slight increase in thickness. The terminal Outer Diameter increase in the end (over the original) may be only as much as 1mm in the end. At least in this usage case, the difference is a tighter seal! And these worked VERY well for replacements.

It may be the nature of DuPont’s Viton that these O-Rings do not offer much stretch at all. The old (perhaps standard rubber) O-Rings were very easy to remove from their seats and stretched easily over the wider shaft to remove them.

I have a pressure washer hose reel from Northern Tools (General Pump brand), and the swivel on the side blew one o-ring (there are 2 o-rings total in the swivel and they are the same size, this one from Amazon). I looked everywhere for a General Pump swivel rebuild kit (which they do make), and everyone said they were on a 3 month back order. So after some measurements I found that this Amazon o-ring was a perfect match. Install 2 new Viton o-rings, put a little silicone grease on the o-rings, and the swivel works like new with no leaks. Plus, I have some extras now just in case it happens again!
I do recommend these Viton o-rings,
I looked for this O-ring specifically to fix a leak in the power steering fluid reservoir of my BMW. BMW apparently has chosen a low-grade O-ring for this application and this is a common leak problem that results in dried oil crusting around the reservoir. BMW uses ATF for power steering and so I did some research to see if there would be a better choice material for this application and was pretty much recommended by everyone and everything i read to use Viton. This O-ring is a perfect fit for the power steering cap (that says "ATF only" on it) and my leak has stopped now. I've only had it for a few months so it's hard to say at this point how well the O-ring is performing. The factory O-ring usually starts to show signs of leakage after a couple of years. I'll report back after a few years, but this option is much cheaper than buying the factory power steering cap (in order to get a new O-ring) and I can now recommend it to other BMW owners as well.
