Detailed Engineering Specifications

Engineered for reliability and performance, this industrial O-ring boasts a precise Inside Diameter of 7.655 inches and an Outside Diameter of 7.721 inches, with a nominal Cross Section of 0.169 inches. The core material, Silicone, provides excellent flexibility, temperature resistance (-50°C to +200°C), and chemical inertness. The integrated Nylon reinforcement enhances tensile strength and abrasion resistance, making it suitable for moderate pressure applications where standard silicone might degrade. Its durometer rating ensures a tight, conforming seal against mating surfaces, preventing leakage in critical systems.
