A seal that is made between two stable and immovable components
O-Rings, Back-up Rings, Square Rings, V-Rings, Dual Seals…
Manufacturers, of course re-name their products in order to enhance sales but essentially the above constitute the common names for the seals.
How does a Static Seal Work?
A static seal is located in a groove and sees no movement – only sealing within its confined space, acting like a gasket between the mating surfaces.
Examples include seals for flanges, plugs, and tubing. As pressure increases, it deforms and reshapes the seal so that sealing pressure increases to
withstand the greater containment requirements. O-rings, V-rings, and other shapes are typical examples.
