PTFE Sealing Technology & Low Friction Advantage
☑ The SPGO seal is a double-acting piston seal designed for heavy-duty hydraulic applications, offering superior performance and reliability.
☑ It features a two-piece design: a bronze-filled PTFE slipper ring that provides low friction and high wear resistance, and an NBR O-ring as an energizer.
☑ The bronze-filled PTFE material ensures excellent sliding properties, minimizing stick-slip and extending the seal's service life under high pressures.
☑ This seal type is well-suited for demanding environments, handling pressures up to 60 MPa and a wide temperature range from -30°C to +100°C.
☑ Its compact design fits standard ISO 7425/1 grooves, making it an ideal choice for hydraulic cylinders in construction machinery, presses, and mobile hydraulics.
