Product Description

This O-ring is made of translucent polyurethane and has a durometer of 70A. It has a round cross-section and can be used across a wide temperature range (-60 degrees F/-51 degrees C to 212 degrees F/100 degrees C). Designed for use in a wide variety of sealing applications, this polyurethane O-ring meets standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings.

Polyurethane is resistant to oil, weather, ozone , heat, electricity, abrasion, tearing and many chemicals. It performs well in low temperatures, but is not recommended for continuous use in high temperatures or with super-heated steam.

The durometer hardness of this polyurethane O-ring is 70A. 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.

I purchased these to use on the outside of hard plastic straws, but up next to the inside of the lid of plastic insulated glasses. When the glasses are turned over, if these O-rings are snug to the top of the inside of the lid, there are no spills, or at least not before you can pick up the glass. Some liquid might actually come out of the straw. This has been a carpet and table saver around my 5 and 7 year old grandchildren. With the o-rings being clear, they look nice inside the lid and on the clear hard plastic straws. The kids don't like them much because they can't pull the straws out of the glasses.

Less than a dollar each, but if you need to get these from a dealership, the price goes up to 20 dollars each.
