Detailed Engineering Specifications

Designed for demanding industrial environments, this silicone O-ring offers superior resilience and chemical resistance. The precise dimensions of a 1.326" inside diameter, 3.077" outside diameter, and a 0.155" cross-section ensure a tight, leak-proof seal. The inherent properties of silicone, enhanced by the brass infusion, allow for operation across a wide temperature range and resistance to many industrial fluids. This makes it a critical component in hydraulic systems, pneumatic assemblies, and chemical processing equipment where consistent performance is paramount.
