Standard vs. UL Listed O-Rings: When to Use Each

Summary Introduction Standard and UL-listed o-rings often appear similar in size, material, and installation, yet the specification behind each designation can carry different performance and operational implications. In many systems, selecting the correct seal is a decision that must align with the equipment’s safety expectations, operating environment, and level of risk. Understanding the difference between […]

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 […]
