GUS-332/F8503 2-Wire Hydraulic Hose for JCB 3CX / 4CX Servo Control Valve
JCB Code: JCB-026 | OEM: GUS-332/F8503 | Brand: GEARUP SUPPLY | Origin: Hungary
Standard: EN 853 2SN | Working Pressure: 约280-350 Bar (4000-5000 PSI) | Burst Pressure: >1000 Bar（约14500 PSI） | Temp Range: -40°C 至 +100°C（间歇+120°C）
Compatible Models: Select Telehandlers — Servo Control Valve Lines | Note: JCB uses BSP/JIS threads, not SAE; match when replacing
The GUS-332/F8503 is a precision 2-wire braided hydraulic hose assembly manufactured by GEARUP SUPPLY in Hungary, engineered for loader-end and excavator-end servo control valve circuits in JCB 3CX, 4CX Backhoe Loaders, and select Telehandler models. Built to SAE 100R2AT / EN 853 2SN standards, this hose delivers precise hydraulic control for servo-operated functions.
With a nominal diameter of DN 10 or DN 12, an inner diameter of approximately 12.7mm (1/2″), an outer diameter of approximately 21.5-22.0mm, and an end-to-end length of approximately 740mm, this assembly handles working pressures of 280-350 Bar (4000-5000 PSI) with burst pressure exceeding 1000 Bar (~14500 PSI). Operating range is -40°C to +100°C, with intermittent tolerance to +120°C.
Fitted with JCB-specification 1/2″ BSP female swivel or JIS parallel thread connectors (typically 90° elbow on one end, straight on the other), this hose requires careful thread matching as JCB uses BSP/JIS rather than SAE threads.
