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.

Couldn’t find a replacement lid for my Bonavita coffee pot. I saw a post about these seals and they work great!

These o-rings fit the legacy Starbucks tumblers that I purchased in ~2000-2004.

Bearing carrier o-ring for a 1984 johnson 50HP cost 3x more. Ordered this and it worked out just great. In fact, this worked out so much better. This o-ring is a hair thicker and wide which is actually much better.

I have a Bonavita BV1900TS with a stainless pot. The pot has a lid that was leaking due to the bad rubber gasket. this item was the correct size to replace the rubber gasket that was on the lid of my coffee pot carafe.

These o-ring seals are amazing! They fit and seal perfectly. My coffee is now piping hot again and they stopped the drip I had when pouring. I highly recommend these.

Used this to try & replace a rubber gasket for gas cap on John Deere trading mower as I couldn't find an exact replacement just for that part. I use 2 together & it works fairly well. Definitely less gas leakage from cap while mowing.
