803198646 XCMG GR2605 motor grader pressure testing hose

803198646 XCMG GR2605 motor grader pressure testing hose

The 803198646 pressure test hose is an original equipment manufacturer (OEM) testing component for the XCMG GR2605 motor grader. Its core function is to accurately acquire hydraulic system pressure parameters, adapting to the pressure testing needs of each critical hydraulic circuit in the machine. This directly impacts the accuracy of system fault diagnosis, pressure calibration, and performance tuning. In equipment maintenance, operational condition monitoring, and troubleshooting scenarios, it can withstand high-frequency pulse pressure and instantaneous high-pressure impacts, and is less prone to deformation, leakage, or excessive pressure loss. This effectively improves testing efficiency and data reliability, providing precise data support for hydraulic system maintenance.

The pressure testing hose features a four-layer reinforced composite structure. The inner tube is made of high-pressure resistant fluororubber (FKM), with an oil swelling rate of ≤1.8%, compatible with XCMG original L-HM 46/68 anti-wear hydraulic oil and testing media, ensuring no media contamination during measurement. The middle layer is a high-strength stainless steel wire braided reinforcement layer, using a double-layer cross-braiding process, with a tensile strength ≥2200MPa, excellent pulse fatigue resistance, and can withstand more than 10,000 high-pressure pulse cycles. The outer rubber layer is made of wear-resistant and anti-aging polyurethane material with a Shore hardness of 72HA, exhibiting outstanding resistance to ultraviolet rays and sand and gravel abrasion, and showing no cracking or splitting after 8000 hours of outdoor aging testing. The connector is made of precision forged brass, nickel-plated for corrosion protection, and features an integrated design of quick connector and sealing gasket, achieving an IP67 protection rating. It is compatible with original factory pressure sensors, pressure gauges, and other testing equipment, offering convenient installation and a secure connection.
