British Standard (BS) O-rings are used in a wide range of industries. Like all O-rings, they are designed to prevent leaks. They fit between two or more parts to create a fluid- and air-tight mating surface. While they look like … Read More

Not all mechanical seals are made of a single piece of material. Filled PTFE seals, for instance, feature an inner core and an outer jacket. The outer jacket is made of polytetrafluoroethylene (PTFE), but the inner jacket is made of … Read More

Polyacrylate (ACM) O-rings have become increasingly popular in recent years. Consisting of polymerized ester and a curing monomer, they are used in the automotive and aerospace industries. Like all O-rings, ACM O-rings are designed to contain fluids and gases so … Read More

Perfluoroalkoxy (PFA) is a common material in which encapsulated O-rings are made. A type of fluoropolymer, it offers excellent flexibility and durability. Encapsulated O-rings, of course, are circular mechanical seals with a flexible internal energizer or core and a more … Read More

Fluorocarbon is a popular material used in the construction of O-rings. As the name suggests, it’s an organic compound consisting primarily of fluorine and carbon. Depending on the specific type, it may contain other elements like chlorine and hydrogen. Fluorocarbon, … Read More

When shopping for O-rings, you may come across the terms “solid core” and “hollow core.” They are used to describe the internal energizer. All encapsulated O-rings have a component that imparts memory to the seal. Known as an internal energizer … Read More

O-rings are essential for preventing leaks. Also known as toric joints, they are commonly found around mating surfaces. O-rings seal mating surfaces so that pressurized water, fluid or gas can travel through the parts without leaks. When shopping for O-rings, … Read More
