– Product Model: 800357055
– Product Name: Lower Rubber Cover (Special for XCMG Construction Machinery, Sealing and Protective Type)
– Material Specifications: High-quality nitrile rubber (NBR), precision molded, conforming to XCMG original factory standards, GB/T 3452.1-2005 national standard and relevant industry standards.
– Structure: One-piece sealing structure, smooth surface without burrs or bubbles, excellent elasticity, adaptable to corresponding interface specifications, tight fit without falling off.
This rubber cap solves the problems of traditional rubber caps, such as poor sealing, easy detachment, poor oil resistance, and easy aging and deformation. It is made of nitrile rubber through a precision molding process, with a Shore hardness of 65±5 degrees, excellent elasticity and resilience, and excellent oil resistance, water resistance, and aging resistance. It can withstand extreme temperatures of -40℃ to +120℃ and salt spray resistance of ≥100 hours. The size is precisely matched to the original installation position and is compatible with corresponding interface specifications. It is easy to install and can be directly embedded for replacement. It effectively prevents dust, water vapor, oil and other impurities from entering the equipment and prevents media leakage, meeting the stringent outdoor use requirements of XCMG equipment.
