he Pneumatic LBH sealing ring is a robust, multi-purpose sealing solution engineered for demanding industrial environments. Its acronym “LBH” stands for its integrated three-layer functionality: a primary Lip seal for reliable low-friction sealing, a rigid Buffer ring for anti-extrusion support against pressure spikes and side loads, and a heavy-duty Hydraulic-style wiper (scraper) for maximum contaminant exclusion. Constructed typically from wear-resistant polyurethane and reinforced thermoplastics, it is specifically designed for harsh applications such as mobile machinery, mining, and food processing, where exposure to dirt, moisture, and chemicals is common. This triple-action design ensures extended cylinder life, minimal maintenance, and reliable zero-leakage performance under challenging pneumatic operating conditions.
