The USH‑type piston & tie‑rod combined seal is a versatile dual‑purpose hydraulic sealing element suitable for both piston and tie‑rod installation, extensively used in engineering machinery, hydraulic cylinders, injection‑molding machines and general‑purpose industrial hydraulic systems. Made of high‑quality polyurethane and elastic composite materials, this multi‑functional seal features excellent wear resistance, pressure resistance and elastic resilience under reciprocating dynamic working conditions.
Its specially optimized lip structure creates uniform surface contact pressure whether mounted on piston grooves or tie‑rod positions. It efficiently prevents hydraulic‑medium leakage and resists extrusion under cyclic pressure load. Thanks to dual‑purpose design, one single seal part can satisfy both piston sealing and rod‑side sealing demands, simplifying spare‑part management and reducing inventory pressure for equipment operators.
The USH‑type combined seal runs stably within a wide pressure and temperature scope and shows good compatibility with mineral‑based hydraulic oil. It resists stick‑slip during frequent extension and retraction movements. Standard groove dimensions allow quick installation without extra machining. Reliable sealing performance helps lower failure rates of hydraulic assemblies and cut down maintenance and component‑replacement costs. Custom sizes and material grades are available to meet diverse specification requirements for worldwide industrial buyers.
