Special Seal For SPGO Piston Seal

Hydraulic cylinder piston seal for excavator Operating conditions: Material: Polyurethane + Nitrile Rubber Temperature: -35~100°C Working pressure: ≤35mpa Speed: =1.0m/s Working medium: hydraulic oil Design description: SPOU is a bidirectional sealing component made of high-performance thermoplastic polyurethane material, consisting of a sealing ring and a It is composed of an O-ring for elastic compensation. The two outer sealing lips serve as the primary seal, utilizing liquid pressure from one side of the system to provide sealing effects, while simultaneously preventing the buildup of liquid pressure on the working surface of the entire sealing system, thereby reducing the risk of leakage. The support ring located in the middle of the sealing surface, along with the raised edges of the sealing lips on both sides, increase the specific pressure, enhancing the sealing effect. Features:   Dynamic and static sealing are effective, wear-resistant, and easy to install     Hydraulic cylin…
