With a durometer of 70A, these translucent rings provide excellent resistance to penetration and are suitable for extreme temperatures, meeting the rigorous standards of Aerospace Standard AS568A. ## 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. ## Features - Made of translucent polyurethane for use with a variety of chemicals and applications - Durometer (hardness) of 70A for resistance to penetration - Round cross-section provides a seal between cylindrical overlapping surfaces - For use across a wide temperature range from -60 degrees F/-51 degrees C to 212 degrees F/100 degrees C) - Meets standards defined by Aerospace Standard AS568A ## Images ![112 Polyurethane O-Ring, 70A Durometer, Round, Translucent, 1/2" ID, 11/16" OD, 3/32" Width (Pack of 10) - Image 1](https://m.media-amazon.com/images/I/713ku9TL4DL.jpg) ![112 Polyurethane O-Ring, 70A Durometer, Round, Translucent, 1/2" ID, 11/16" OD, 3/32" Width (Pack of 10) - Image 2](https://m.media-amazon.com/images/I/51bid7qjm5L.jpg) ## Available Options This product comes in different **Nominal Width, Size, Nominal Inside Diameter, Nominal Outside Diameter, Outside Diameter, Inside Diameter String, Number of Items, Item Width String** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well made *by F*** on Reviewed in the United States πŸ‡ΊπŸ‡Έ on February 25, 2023* Very well made with accurate sizing and quality materials. ### ⭐⭐⭐⭐⭐ Good replacement for Hydro Flask straw lid *by M***Y on Reviewed in the United States πŸ‡ΊπŸ‡Έ on January 2, 2023* Lost the small O-ring in my Hydro Flask straw lid.
