Product DescriptionO type ring φ125×7This large O-ring, sized at 125mm inner diameter and 7mm cross-section, is engineered for static sealing applications in industrial machinery, particularly within hydraulic systems and large pumps. Its primary role is to create a leak-proof barrier between two stationary components, such as flanges, covers, or housing parts, preventing the escape of hydraulic fluid, oil, or other media, and blocking the entry of contaminants. Manufactured typically from Nitrile rubber (NBR), this O-ring offers superior resistance to petroleum-based oils, hydraulic fluids, greases, and water, making it an ideal choice for a vast array of industrial equipment. The 7mm cross-section provides a robust sealing element capable of handling higher pressures and offering greater stability in larger diameter glands compared to thinner sections, reducing the risk of extrusion under pressure. For optimal performance, the O-ring must be installed in a correctly designed gland. The gland dimensions must provide the appropriate compression (usually 15-30% for static seals) to deform the O-ring slightly, creating the initial seal. The gland must also have adequate volume to accommodate any swelling of the elastomer due to temperature changes or fluid absorption. The sealing surfaces must be smooth, free of burrs, scratches, or tool marks that could compromise the seal. Installation requires careful handling to avoid twisting, stretching, or cutting the O-ring; using lubrication can facilitate installation, especially for larger rings. This O-ring is a critical component for ensuring the integrity and efficiency of hydraulic systems and other fluid power applications, helping to maintain pressure, prevent fluid loss, reduce downtime, and protect the environment from leaks.Product Description
