Rubber seals are used in numerous industries to prevent the unwanted leakage of liquids and gases in various components such as pumps, valves, pipe fittings, and vacuum seals, to name only a few. However, all seals are not created equally. Rubber seal design consists of several elements to ensure that the seal delivers optimal performance [...]
Fluid power seals used in pneumatic cylinder systems represent some of the most overlooked, yet vital components in its construction and operation. Without these rubber seals – or if using inferior seals – the friction and leakage created by the process of using a pneumatic cylinder application could cause the equipment to catastrophically fail, risking [...]
Since our founding in 1955, Precision Associates, Inc. (PAI) has become a trusted name among manufacturers for our reliable, high-quality rubber compounds. We use these compounds to create a variety of parts, specializing in rubber seals and gaskets, as well as rubber O-rings. While these components are used in a number of industries, they are [...]
As their name suggests, O-Rings — sometimes referred to as preformed packings — are doughnut-shaped gaskets that serve as seals. They need to be slightly deformed — that is, squeezed and stretched — in order to function properly. Each side of an O-Ring is squeezed between the walls of whatever space the seal is going [...]
