HBTU Rod Seal – Heavy-duty double-acting rod seal with U-cup geometry and multiple anti-extrusion backup rings. Multi-lip configuration provides positive sealing in both directions under extreme pressures and severe side-load conditions. Reinforced backup rings deliver superior extrusion resistance against pressure spikes, shock loads, and cyclic fatigue. Optimized lip profile reduces friction, stick-slip, and operating temperatures for extended service life. Rugged construction excels in mining, construction, and heavy-equipment hydraulic cylinders. Material: high-grade polyurethane with robust backup elements. Temp: –40°C to +110°C. Pressure: up to 50 MPa.
