EO/EO2 Fittings

Parker EO and EO-2 Fittings are high-performance metric tube fittings designed for reliable, leak-free connections in hydraulic systems. With proven bite-type technology (EO) and elastomeric sealing technology (EO-2), they ensure safety, efficiency, and long service life across a wide range of industrial applications.

Parker EO/EO-2 Fittings are engineered to meet the highest standards of hydraulic connection reliability. The EO Fitting uses a cutting ring (bite-type) design for strong, vibration-resistant connections, while the EO-2 Fitting enhances this with elastomeric seals, eliminating leak paths and reducing assembly time. Manufactured to ISO 8434-1 / DIN 2353 standards, they are available in Light, Heavy, and Extra-Heavy Series to suit different pressure requirements. These fittings are widely used in mobile hydraulics, machine tools, industrial equipment, and process industries, offering superior performance, corrosion resistance, and ease of installation. By minimizing leakage and downtime, Parker EO/EO-2 Fittings help increase system efficiency and reduce operating costs.
