## Overview

This pack of 25 red silicone O-rings features a 70A durometer hardness and meets aerospace standard AS568A, delivering exceptional sealing performance across a vast temperature range (-65°F to 450°F). Engineered for chemical resistance and durability, these O-rings are ideal for industrial, automotive, and hydraulic applications requiring reliable, long-lasting seals.

## Description

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.

Review: Great Replacement for John Deere Hydraulic Couplers - I bought these O-Rings to replace the leaking seals inside the front hydraulic couplers on my John Deere 318. They fit perfectly and stopped the constant slight leaks with attachments plugged into them.
Review: Worked in my Umarex Fusion... - Just bought these to use in the pressure valve in my Umarex Fusion CO2 .177 pellet gun. No leaks! The 25 count will last a while. I previously bought five of the black o-rings for the Fusion off of ebay for nearly the same $, and they did not work.
