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.

You won't believe how I used these O-Rings, as replacement traction wheels on my rowing machine. Under the seat are 4 roller wheels that had rubber tires which over the years disintegrated. Searched for O-rings that had the proper diameter and thickness that popped onto the wheels as perfect replacement tires. These tires should last for many years, if not, the bag of 10 provides another full set of tires at very low cost.

Saved the day! Could not find these in any pool supply store and when I finally did they were very costly. These were very inexpensive and came in a timely manner.

This was harder than described but customer service was great and refunded. It would work great for other applications, good quality o-ring.
