Genuine XCMG Pressure Measurement Hose Assembly with OEM number 803198195 is an essential diagnostic tool for motor grader hydraulic systems. This high-precision hose assembly, 803198195, enables accurate pressure readings in brake circuits, steering systems, and implement hydraulics. Manufactured to exact XCMG specifications, it features a braided stainless steel outer layer, PTFE inner core, and swivel fittings for leak-free connections.
Designed for GR215, GR300, and GR350 motor graders, the 803198195 pressure measurement hose assembly connects directly to test ports on hydraulic pumps, valves, and cylinders. Its flexible design allows easy routing in tight engine compartments, while the integrated pressure gauge adapter (optional) provides real-time system diagnostics without disassembling original hoses.
By using OEM 803198195, maintenance teams can quickly identify pressure drops, pump wear, or valve leakage, reducing troubleshooting time by up to 60%. This genuine XCMG assembly guarantees compatibility and safety up to 400 bar working pressure.

The XCMG 803198195 pressure measurement hose assembly utilizes a PTFE inner core with zero volumetric expansion, ensuring pressure readings are not dampened or delayed. The stainless steel braid provides exceptional kink resistance and protects against abrasion in harsh undercarriage environments.
Each end fitting is equipped with a swivel nut that allows easy alignment with test ports without twisting the hose. The integrated dust caps prevent contamination ingress when not in use, maintaining cleanliness for repeat measurements.
The 803198195 hose assembly is primarily used to connect pressure gauges to test points on the main hydraulic pump, brake accumulator, and steering control valve. It enables technicians to verify pump output pressure (typically 180–210 bar) and detect internal leakage.
During circle drive diagnostics, this hose helps measure charge pressure for the hydrostatic transmission. For blade lift cylinders, it allows dynamic pressure testing under load, identifying seal bypass or valve spool wear.
Routine use of OEM 803198195 reduces guesswork and prevents unnecessary component replacement, saving both time and money.
Before connecting, ensure the pressure gauge range matches the expected system pressure (recommended 0–600 bar). Remove the test port dust cap and hand-tighten the 803198195 swivel nut – do not use tools to avoid over-torque.
After connection, slowly pressurize the system and check for any leakage at fittings. Never bend the hose below its 50 mm minimum radius. After measurement, depressurize slowly, disconnect, and replace both dust caps.
Inspect the hose assembly regularly for cuts, abrasion, or bulging. Replace every 2 years or after 500 measurement cycles, whichever comes first, to maintain accuracy and safety.
Generic pressure hoses often use rubber cores that expand under pressure, causing reading errors up to ±8%. The PTFE core of 803198195 ensures ±1% accuracy. Aftermarket fittings may have mismatched thread pitch, leading to cross-threading and port damage.
Genuine XCMG hoses are pressure-tested to 600 bar (1.5x working pressure) and certified leak-free. The stainless braid resists crushing and abrasion, while generic braids fray quickly in dusty environments.
Investing in OEM 803198195 ensures reliable diagnostics and eliminates safety risks from burst hoses.
Each 803198195 assembly is manufactured in XCMG’s ISO 9001:2015 certified facility. Every hose undergoes 100% proof pressure testing (600 bar) and helium leak detection. Fittings are torqued to exact specifications and marked with batch numbers.
Full traceability from raw material to finished product allows quality audits and ensures compliance with global machinery standards. XCMG offers a 12-month warranty against manufacturing defects.
OEM 803198195 replaces older part numbers 803198190 and 803198192A. It is compatible with all XCMG motor graders from model year 2010 onward. For older machines, verify test port thread size (M16×1.5).
Order this hose assembly together with digital pressure gauge 803198196 for a complete diagnostic kit. Bulk discounts available for dealer workshops. Store in a clean, dry place away from direct sunlight.
Q: Can the 803198195 hose be used with water-based fluids? A: Yes, PTFE is compatible with water-glycol and water-oil emulsions. Avoid phosphate esters.
Q: What is the recommended pressure gauge connection? A: Use a gauge with G1/4” male thread and a M16×1.5 to G1/4” adapter (not included).
Q: How to detect internal leakage in the hose? A: After disconnecting, blow compressed air (5 bar) through one end; feel for flow at the other end – any obstruction indicates debris.
Q: Is the hose field repairable? A: No, replace the entire assembly if damaged. Do not attempt to cut or re-terminate.
