The more internal pressure is applied to this join, the more the o-ring is distorted inside its groove, which can improve its overall sealing force up to a point - but beyond a certain pressure, or under more dynamic workloads, this can cause failure of the seal. It's important to get the balance right between o-ring material, size and working environment in order to fulfil the role you need it to perform.

These utensils are an environmentally-friendly alternative to plastic, and are compostable, which makes them a much better choice for consumers that care about the earth. They're completely organic and smooth, with no coatings, bleach, or dye. Each knife, spoon and fork feels as comfortable to eat off of as any plastic utensil, and as sturdy as metal utensils. With a flat, even surface, you'll never have to worry about splinters or breakage.
