About This Product
Need to seal a hydraulic piston or shaft? These PU U-rings (also called UN, UNS, UHS, or Y-rings) are exactly what you're looking for. Made from polyurethane, they're designed to handle oil and pressure in hydraulic systems. Available in heights from 5mm to 10mm to fit various applications. Brand new, unused, and ready to install. Great for machinery, automotive repairs, industrial equipment, or DIY projects. Generic/unbranded but made to standard dimensions. If you're replacing worn seals or assembling a new system, these rings help prevent leaks and keep everything running smooth. Simple, effective, and essential for hydraulic maintenance.
