Rubber Compound Data sheets usually display a number of physical properties as recorded from standard test methods. Among the most common are three measured on the Tensometer – Tensile Strength (at break), Ultimate Elongation, and Modulus of Elasticity. The Test The Tensometer stretches a specimen, or dumbbell, cut from a sheet of rubber, until it [...]
As the name implies, these O-Rings are used to seal Straight Threaded Tube Fittings. As with other O-Rings in static application designs, they make a seal between two mating components. Unlike most O-Rings, they are not completely housed in a rectangular groove or gland. The threaded male tubing fitting does contain a radiused partial groove [...]
How does rubber get into food you ask? Food Processing machines have rubber seals in them. The seals are exposed to harsh chemicals during the cleaning and sanitizing process or can wear over time causing the rubber to breakdown. Seals made from rubber that have been compounded to withstand caustic chemicals should be used in [...]
Since 1955, Precision Associates Inc. has been proud to offer top-quality precision-molded rubber goods. We established our reputation by designing top-quality O-rings for everyday use. In 1956, cofounder Arnold Kadue noticed how ubiquitous O-rings were becoming in contemporary applications. However, these O-rings were also constructed from prohibitively expensive materials, and he directed PAI to find [...]
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 [...]
