LH (Low-Height) series represents a breakthrough in space-constrained sealing solutions, delivering full-performance sealing in 40-60% less axial space than conventional designs. Through innovative material science and compression-optimized geometry, LH seals enable cylinder miniaturization without compromising sealing integrity.
Multi-Function Integration: Combines primary seal, anti-extrusion, and guide functions in single compact unit
Asymmetric Lip Geometry: Maximum sealing force in minimum axial dimension
Radial Preload Optimization: Maintains contact pressure across entire working range
LH-Elastomer™: High-modulus polyurethane compound with carbon nanotube reinforcement
Compression Recovery: 99% shape recovery after 100% compression at 150°C
Space-Stable Formulation: Zero creep or cold flow in confined installations
