Advantages: Very good resistance to oil and gasoline; superior resistance to petroleum-based hydraulic fluids; wide range of service temperatures (Negative 65 to 300 degrees F); good resistance to hydrocarbon solvents; very good resistance to alkalis and acids.
Limitations: Inferior resistance to ozone, sunlight, and natural aging; poor resistance to oxygenated solvents
Remarks: Nitrile and neoprene are the highest-volume oil-resistant elastomers. Nitrile is superior to neoprene in resistance to oil, gasoline, and aromatic solvents. However, it does not perform as well as neoprene in applications requiring exposure to weather, ozone, and sunlight. Furthermore, it has no inherent flame resistance.
The properties of nitrile vary considerably with the ratio of acrylonitrile and butadiene. In general, as the acrylonitrile content of the elastomer increases, oil and solvent resistance and abrasion resistance improve. When the acrylonitrile content decreases, these properties deteriorate, and low-temperature flexibility and resilience improve.When nitrile is modified by polyvinyl chloride (PVC) resins, its resistance to weather, ozone, and sunlight improves considerably without significant sacrifice in oil-resisting properties. PVC/nitrile is similar to neoprene, in general, however, it is much inferior to neoprene in adhesion to fabrics and metals.
Carboxylated nitrile is generally tougher and more resistant to tear and abrasion than conventional nitrile, but it is less resilient and flexible at low temperatures.

Bought these to use as a shock absorber, not the intended use but these are thick and perfectly sized.

I purchased These two afford a tighter seal on the Toro lawnmower gas cap. I lost the first cap and purchased a replacement from Toro, which was a very loose fit and often vibrator off. These gaskets mow afford a tight seal.

the rings are for a 2.5 cam lock seal, and yes, they fit that, but i was looking for a 2.5 OD ring. i'm keeping these, they are mint high quality. got them on time, and in excellent condition.i was not planning to use these on the cam lock, but i now can, and will.yes, i would order these again,

Although these replacement washers fit, they are allot softer than the original washers we’ve had. As a result these washers don’t hold up in the fire hose as they eventually split from being attached and detached to each other or the fire hydrant.
