Volumetric Swell vs. Hardness Shift in Elastomers

Summary Why Swell and Hardness Matter in Seal Performance When an elastomer seal is exposed to fluids over time, two material-level changes largely determine its long-term reliability: volumetric swell and hardness shift. These parameters capture how the seal’s size and stiffness evolve due to chemical exposure. Excessive swell or a significant change in hardness can […]

Hose O-Rings for Reliable Hydraulic Sealing

Summary How Hose O-Rings Support System Efficiency O-Rings play an essential role in maintaining system efficiency in hydraulic and pneumatic hose systems. By creating a precise, leak-tight seal between hose fittings, adapters, and couplers, hose o-rings prevent fluid loss, sustain operating pressure, and protect against contamination. Just a small leak can make a big impact. […]

Dominando as escalas de durômetro de anel de vedação

Summary Introduction O-Rings provide critical sealing functions that prevent leaks and maintain system pressure across a wide range of industrial applications. Their performance and service life depend on several factors, including material composition, size, and hardness. O-Ring hardness, measured using the durometer scale, plays a central role in determining sealing performance. Durometer influences key characteristics […]
