4071215 Excavator Hydraulic oil pipe clamp for ZX200-5B 

Hitachi original excavator hydraulic oil pipe clamp (part number: 4071215) is a key fastener used to fix hydraulic oil pipes and prevent them from wearing or falling off due to vibration. According to market accessory information, the pipe clamp corresponding to this part number is usually suitable for Hitachi ZAXIS series small and medium-sized excavators, such as the boom, boom, or chassis hydraulic pipelines of ZAXIS 60, ZAXIS 65, ZAXIS 70, ZAXIS 75 and other models. As an original accessory, its design dimensions (such as bolt hole diameter, clamping inner diameter) are precisely matched with the layout of the main engine pipeline.

The hydraulic oil pipe clamp is usually made of high-strength steel stamping or casting, and the surface is treated with rust prevention such as galvanizing or spraying, which has good corrosion resistance and mechanical strength. Its structure is mostly designed as a double hole "butterfly clip" or "clamp", which generates uniform clamping force through bolt fastening, firmly fixing the hydraulic oil pipe in the preset slot of the frame or working device, effectively suppressing the vibration and displacement of the pipeline under high pressure pulses, and preventing damage caused by friction with adjacent components. As an original component, its bolt specifications (such as 8mm, 10mm, or 12mm screws) have a high degree of matching with the installation holes, ensuring a firm and non slip installation. Some pipe clamps may also be lined with rubber or nylon pads on the inner wall to protect the outer rubber layer of the oil pipe and reduce noise.

The maintenance core of this oil pipe clamp lies in regularly checking the fastening status, preventing rust, and correctly installing it during pipeline replacement. Regular inspection: It is recommended to check the fixing bolts of all oil pipe clamps for looseness, missing or rust every 250 working hours or weekly maintenance, and use a torque wrench to recheck and tighten according to the manufacturer's required torque (such as 65 ± 5 N · m). Inspection and Cleaning: Visually inspect the clamp body for cracks, deformation, or severe corrosion, and clean the clamp and surrounding areas of oil and soil to prevent further corrosion.
