Selecting Teflon® Encapsulated O-Rings for Reliable Sealing

Summary Introduction Teflon® encapsulated o-rings provide reliable sealing in environments where chemical exposure, temperature variation, or cleanliness requirements challenge standard elastomer materials. By combining a chemically resistant fluoropolymer jacket with a resilient elastomer core, these seals offer a practical solution when compatibility and long-term stability are critical to system performance. What Are Teflon® Encapsulated O-Rings? […]

How Tensile Strength Affects O-Ring Performance

Summary Introduction Tensile strength is a fundamental mechanical property that influences how elastomers respond to stress, deformation, and repeated loading. In sealing applications, this property helps determine whether an o-ring can withstand the mechanical demands encountered during installation and service. While tensile strength is often listed as a single value on a material datasheet, its […]

O-Ring Groove Design Calculator: Engineering the Right Gland Geometry the First Time

Correct O-ring groove design is a multi-variable problem with tighter tolerances than most engineers initially expect. Squeeze, gland fill, extrusion resistance, and tolerance stack-up all interact — and an error in any one of them can produce leakage, premature elastomer degradation, or catastrophic seal extrusion. Global O-Ring’s O-Ring Groove Design Calculator encodes the published design […]

How O-Rings Ensure Reliable Connector Sealing

Summary The Role of O-Rings in Connector Sealing Systems In many applications, connectors serve as sealing interfaces that must protect the connection from external exposure while maintaining system integrity. O-Rings serve as the sealing element, helping connectors resist leakage and contaminant ingress. When integrated into the connector design, they create a barrier that helps protect […]

Viton® (FKM) O-Rings: Properties, Grades, and Industrial Applications

Summary What Are Viton® O-Rings? Viton® (FKM) o-rings are fluoropolymer elastomer seals engineered for extreme service conditions where standard rubber compounds fail. Developed in the late 1950s by DuPont, Viton® is a registered brand name for FKM — fluoroelastomer — a synthetic rubber defined by its high fluorine content. That fluorine content is the source […]

Bonded Seals for High-Pressure Threaded Connections

Summary Introduction Threaded connections are widely used to contain pressurized fluids and gases in hydraulic, pneumatic, and fluid handling systems. As pressure increases, sealing reliability depends not only on material selection but also on how compression and load are controlled within the connection. Bonded seals address these demands by combining structural support with elastic sealing […]
