As a material, Polyurethane (AU/EU) is known for toughness that outperforms conventional rubber compounds, very high tensile strength and load capacity. The compound resists extrusion under high pressure, petroleum oils, and impact and shock loading. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). It should not be specified for service in ketones or prolonged humidity at elevated temperature.
Common environments for this compound include mining and heavy equipment, construction machinery, and hydraulic cylinders.
Order part number U70108, sold individually. Nominal inside diameter is listed as 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
