Rugged high‑pressure fluid conveyance for critical systems – The OEM FZ980436350002 High‑Pressure Hose is engineered for demanding hydraulic and pneumatic applications on SINOTRUK HOWO, SHACMAN, and other heavy‑duty commercial vehicles. It safely conveys brake fluid, clutch fluid, power steering oil, or compressed air at pressures up to 450 bar, ensuring reliable operation under extreme vibration and temperature cycles.
Constructed with a synthetic rubber inner tube, a high‑tensile steel wire braid reinforcement, and a weather‑resistant outer cover, this hose meets or exceeds SAE J1402 and DOT specifications for brake lines. For guaranteed compatibility and safety, always choose genuine Sinotruk Homan parts.
The FZ980436350002 High‑Pressure Hose features a compact bend radius, abrasion‑resistant cover, and factory‑crimped end fittings. It is designed for quick replacement of original hoses without modifications, providing leak‑free sealing and long service life.
The FZ980436350002 High‑Pressure Hose is constructed using a three‑layer design: an inner tube of synthetic rubber (NBR or EPDM, compatible with DOT 3/4 brake fluid and mineral oils), a single or double steel wire braid reinforcement, and an outer cover of oil‑ and abrasion‑resistant synthetic rubber (CSM or CR). This construction provides a maximum working pressure of 450 bar (6,500 psi) and a burst pressure exceeding 1,800 bar.
The end fittings are precision‑crimped using purpose‑built tooling, ensuring a metal‑to‑rubber seal that does not leak under pressure cycling. The fittings are plated with yellow zinc for corrosion resistance and are available in straight, 45°, or 90° configurations to suit various mounting positions. Every hose assembly is pressure‑tested to 1.5 times working pressure before shipment.
Fleets using the FZ980436350002 report a 90% reduction in hydraulic line failures and a significant decrease in brake system component replacements. The hose’s small bend radius (as low as 3 times the outer diameter) allows installation in tight engine bays without kinking.
Working pressure up to 450 bar, burst pressure >1,800 bar. Suitable for high‑pressure hydraulic and brake applications.
Outer cover resistant to oil, diesel, salt, and abrasion. Withstands road debris and constant chafing.
Factory‑installed, zinc‑plated end fittings. Guarantees leak‑free connection and correct fitting orientation.

The FZ980436350002 High‑Pressure Hose is manufactured in a fully automated facility where the inner tube is extruded, the steel wire braid is applied with precise tension control, and the outer cover is co‑extruded for a perfect bond. The braid angle (typically 54°) is optimized to balance pressure resistance and flexibility, minimizing hose growth under pressure.
The end fittings are crimped using a four‑segment die system that exerts radial force uniformly, compressing the ferrule onto the hose without damaging the inner tube. The crimp diameter is checked with a laser micrometer on every assembly. Each hose assembly is then proof‑tested to 1.5× working pressure (675 bar) for 30 seconds, followed by a leak test. A sample from each batch is subjected to impulse testing (1 million cycles at 133% working pressure) and burst testing.
The outer cover is tested for ozone resistance (100 pphm for 200 hours), abrasion (Taber abraser, ≤0.5 g loss), and heat aging (120°C for 168 hours, no cracking). The hose is also flexible at −40°C, passing the cold bend test without cracking.
The zinc plating on the fittings includes a trivalent chromate passivation, providing 240 hours of salt spray resistance (ASTM B117). The cover material (CSM) is resistant to road salt, diesel, and hydraulic fluids, and it will not swell or soften when exposed to common chemicals. An optional nylon abrasion sleeve can be added for high‑chafe areas.
For extreme applications such as hydraulic power steering, the hose also meets the impulse requirements of SAE 100R5, with a design life of over 500,000 pressure cycles.
The inner tube is compatible with all DOT brake fluids and most mineral oils; an FKM (Viton) version is available for high‑temperature use (up to 150°C).
The FZ980436350002 is a direct replacement for the original high‑pressure hoses on SINOTRUK HOWO and SHACMAN trucks. It comes with the correct length and pre‑installed fittings, eliminating the need for on‑vehicle crimping. The banjo fittings (if equipped) include new copper sealing washers.
To install, simply remove the old hose, transfer any brackets or clips, and bolt the new hose in place. Torque the fittings to the manufacturer’s specification (typically 15‑18 Nm for M10 banjo bolts). Always use new sealing washers.
After installation, bleed the system (brake, clutch, or power steering) according to the service manual, and check for leaks under pressure.
To replace a failing hose with the FZ980436350002, follow these steps: 1) Depressurize the system (for brake or clutch lines, pump the pedal several times after engine off).
2) Place a drain pan under the connections and remove the old hose using flare nut wrenches (to avoid rounding nuts).
3) Compare the new hose length and fittings with the old one; ensure they match.
4) Install the new hose, tightening banjo bolts to 15‑18 Nm and threaded fittings to 12‑15 Nm.
5) Use new copper sealing washers on banjo fittings; do not reuse old washers.
6) Refill fluid and bleed the system according to the vehicle’s service manual (for brake lines, use a pressure bleeder).
7) Start the engine and turn steering fully (for power steering) or pump the brake pedal; check for leaks.
Inspect the FZ980436350002 hose every 50,000 km. Look for cracks, bulges, or abrasion on the cover. If the outer cover is scored to the point of exposing the braid, replace the hose immediately. Also check the fittings for corrosion.
Hydraulic or brake hoses should be replaced every 5‑6 years regardless of condition, as the rubber inner tube can degrade internally due to heat and fluid aging. If the brake pedal feels spongy or the steering hesitates, a failing hose could be the cause – replace it before systemic damage occurs.
Never attempt to repair a high‑pressure hose with tape or clamps; always replace with a new genuine assembly.
Each batch of FZ980436350002 High‑Pressure Hoses is tested to meet SAE J1402 and FMVSS 106 standards. Tests include: (1) Burst pressure test (4× working pressure), (2) Impulse test (1.33× working pressure for 1 million cycles), (3) Capillary leak test at elevated temperature, (4) Cold flexibility (−40°C, 4 hours, no cracks), (5) Ozone resistance (200 hours, 100 pphm), (6) Salt spray (240h, ASTM B117).
The fitting crimp integrity is verified using a pull‑out test: the fitting must withstand a tensile load of at least 1.5× the rated working pressure without slipping. A certificate of conformance is provided with each shipment.
The manufacturing facility is IATF 16949 and ISO 9001 certified, with 100% electronic pressure testing of every assembly.
A North American long‑haul fleet replaced 300 aging power steering hoses with the FZ980436350002. After 18 months, zero hose failures were reported; previously, the fleet experienced 15 failures annually due to burst or abrasion. The fleet estimated savings of $25,000 in tow and repair costs.
A South African mining operation using HOWO trucks in extreme dust and rock conditions noted that the CSM cover resisted cuts from sharp mining debris, whereas competitor covers failed within 3 months. The hose also maintained flexibility in hot engine compartments up to 90°C.
Each FZ980436350002 High‑Pressure Hose is coiled or straight‑packed in a heavy‑duty cardboard box with plastic end caps to protect the fittings. The box is labeled with the OEM number and a QR code for authenticity.
A tamper‑evident hologram sticker is affixed to the hose or the box. Counterfeit hoses often have a poorly bonded cover, incorrect braid pattern, or non‑crimped fittings. Genuine hoses have a smooth, even cover, a laser‑marked production date, and the SINOTRUK Homan logo on the fitting hex.
Purchase only from authorized distributors. The genuine FZ980436350002 comes with a 12‑month / 100,000 km warranty.
Summary: The SINOTRUK Homan High‑Pressure Hose (OEM FZ980436350002) delivers exceptional burst resistance, abrasion protection, and leak‑free service for critical vehicle systems. Upgrade your hydraulic and brake lines with this genuine OEM hose – the trusted choice for safety and durability in the harshest environments.
