12B1744 O-ring Liugong CLGB320C bulldozer spare parts

1 12B1744 O-RING 9.17×1.83

• High-pressure Resistant Structure, Stable Pressure Holding: Adopting customized high-pressure rubber formula, the product has strong bearing capacity against instantaneous hydraulic impact and long-term pressure holding load. It will not warp, extrude or deform under high-pressure working conditions, effectively solving the problem of pressure drop and weak bulldozing power caused by insufficient pressure resistance of ordinary O-rings.
• Excellent Tear & Deformation Resistance: Optimized with secondary vulcanization process, the internal molecular structure is tighter with stronger toughness and tear resistance. During frequent hydraulic commutation and pressure fluctuation of CLGB320C bulldozer, it can resist shear friction and tensile damage, avoiding cracking and failure of conventional sealing rings under variable load conditions.
• Strong Anti-aging & Medium Adaptability: The upgraded material formula has better anti-oxidation and anti-aging performance, and is compatible with various hydraulic oil and lubricating media for construction machinery. It can resist long-term high-pressure oil immersion and temperature alternation, without swelling, shrinkage or hardening failure, maintaining long-term stable sealing performance.
• Original Precision Matching & Low Failure Rate: Strictly manufactured in accordance with the original high-pressure sealing groove tolerance and assembly standards of CLGB320C bulldozer. It features accurate size, precise groove fitting and no extrusion gap. It supports direct in-situ replacement, effectively solves hidden troubles such as high-pressure oil leakage and system pressure instability, and reduces equipment failure and shutdown maintenance frequency.
