## Overview

This pack of ten red silicone O-rings features a 70A durometer hardness and precise 2" ID by 2-1/4" OD sizing, engineered to meet aerospace AS568A standards. Designed for extreme temperature ranges (-65°F to 450°F) and resistant to a wide array of chemicals and fluids, these O-rings deliver reliable, durable sealing solutions for plumbing, automotive, and industrial applications.

## 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: Fits 2” pvc male connector - Sparky here, Fits perfectly over a 2” threaded PVC connector to make a water tight seal without the need for caulk. This will work nicely for my intended purposes.
Review: Rescued my thermos that has the gasket go - A bit bulkier than the seal that came with the thermos, but this helped get a nice coffee thermos to last a lot longer. It doesn't look too appealing, but otherwise, it does the job and keeps the coffee in the thermos instead of letting it dribble out.
