ENDURAFLEX LOADED

Overview

In scenarios where standard U-Cups fail to seal effectively due to low pressure or temperature, opting for a Enduraflex O-Ring Loaded U-Cup crafted from advanced materials like polyurethane, HNBR (Hydrogenated Nitrile Butadiene Rubber), NBR (Nitrile Butadiene Rubber), or FKM (Fluoroelastomer) provides a viable solution. These materials ensure compatibility with a wide array of U-Cup grooves. The inclusion of an integrated O-Ring significantly bolsters sealing performance in challenging conditions, making polyurethane a preferred choice for its robust mechanical properties. Both HNBR and NBR offer excellent resistance to wear and tear, oil, and various chemicals, with HNBR being particularly valued for its superior temperature and ozone resistance. FKM stands out for its exceptional heat resistance and compatibility with a broad range of chemicals, including oil and fuel.

The effectiveness of the Enduraflex O-ring Loaded U-Cup is rooted in the inherent preload of the seal body, enhanced by the compression of the seal lip and the O-Ring upon installation, which, when subjected to operational pressures, improves the radial contact forces. This special configuration, coupled with the O-Ring, guarantees exceptional sealing behavior under varied pressure conditions. The beveled sealing lip is designed to efficiently break the fluid film, ensuring increased sealing force. This design’s benefits are manifold: excellent low-pressure and temperature sealability, easy installation, reduced compression set thanks to the O-Ring, and reliable fluid film disruption. Suitable for a broad spectrum of applications, including hydraulic cylinders, injection molding machines, and machinery used in agriculture and construction, the Enduraflex Loaded U-Cup is a testament to advanced sealing technology’s adaptability and effectiveness.
