Your cart is empty.This silicone O-ring is red in color, round in shape, has a durometer of 7OA, and is designed for use in a wide variety of sealing applications. Silicone is acceptable for temperature applications between -65 degrees F (-54 degrees C) to 450 degrees F (232 degrees C). It has good resistance to ozone, weather, detergent, salt water, engine and transmission oil, non-petroleum brake fluid, hydraulic fluids that resist fire, vegetable and animal oils, and high molecular weight chlorinated aromatic hydrocarbons. Silicone is vulnerable to mechanical wear and tear, water and steam over 250 degrees F (121 degrees C), aromatic hydrocarbons (benzene), chlorinated hydrocarbons (trichloroethylene), acids and bases, and hydrocarbon fuels. 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 a number of sizes, and can be ordered based on required nominal inside diameter (ID), outer diameter (OD), and cross-sectional (CS) diameter. This silicone 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. This silicone O-ring meets standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings.

Perfect fit for my Pentair FNS 48 drain plug. For half the cost of a pool store I now have ten o rings - Thank you!

It fit just right for the seal on the pump sprayer. The original O ring was all cracked and rotted after only 3 months of use, even though I rinsed it thoroughly after each use.

These orings are advertised as ⅛" (0.125") thick. they are actually 0.139" thick, which may work in some cases but it is not what the ad says and not what i need.

I purchased a few different sizes for a project almost a year ago. Tight seal, no leaks, did not break when I expanded them, all good.

I needed replacement O rings for two Hudson garden sprayers. These were a perfect fit and work very well.

Works well does what it need it to do. I am using this o-ring in a very different purpose than it was intended for but it does exactly what I need it to do. Looks like it is dimensionally correct and meets all of its specifications.If I was using it to create a seal I would expect it to be functionally perfect.
