190003179785 Polyamide Tube – HOWO Truck Brake Module

The OEM 190003179785 Polyamide Tube is an essential component specifically engineered for HOWO truck brake systems. This specialized tubing delivers exceptional hydraulic performance in braking applications, ensuring precise pressure transmission between critical components. Manufactured with premium-grade polyamide material, it maintains structural integrity under extreme temperatures ranging from -40¡ãC to 120¡ãC, resisting common causes of failure like oil degradation, moisture exposure, and abrasive wear. The 190003179785 tube’s unique polymer formulation prevents embrittlement that occurs in standard rubber hoses, extending service life by up to 3X compared to conventional alternatives.

Engineering Advantages

Designed exclusively for HOWO‘s heavy-duty braking systems, the 190003179785 polyamide tube incorporates multi-layer reinforcement that withstands burst pressures exceeding 350 bar. This exceeds SAE J844 specifications by over 40%, providing critical safety margins during emergency braking maneuvers. The tube’s smooth internal bore minimizes turbulence and pressure drop, translating to 15% faster brake response times compared to standard alternatives. Unlike metal brake lines, the OEM 190003179785 component eliminates corrosion issues while reducing system weight by up to 60%. Its flexibility enables vibration absorption, protecting connected components from stress fractures.

Installation & Compatibility

The precision-engineered 190003179785 tubing maintains strict dimensional tolerances (¡À0.05mm) ensuring plug-and-play compatibility with all HOWO truck models equipped with pneumatic-over-hydraulic braking systems. Its pre-formed bends correspond exactly to factory routing paths, eliminating kinking during installation. The connector interfaces feature ISO 8434-1 compliant 24¡ã cone fittings that create metal-to-metal seals without requiring thread sealants. Each tube end incorporates CNC-machined collars that prevent compression fitting slippage under high-pressure cycling. For technicians, the polyamide construction allows on-vehicle trimming adjustments without specialized flaring tools when performing custom installations or repairs.

Performance Specifications

• Temperature Resilience: Maintains flexibility from -40¡ãC to +135¡ãC
• Pressure Rating: Continuous 250 bar / 350 bar burst
• Chemical Resistance: Compatible with DOT 4, DOT 5.1, and mineral-based brake fluids
• Abrasion Resistance: 5X greater surface durability than standard nylon
• Bend Radius: Minimum 4x tube diameter without flow restriction

Applications in Brake Systems

In HOWO truck brake modules, the OEM 190003179785 polyamide tube serves as the critical connection between the foot valve and brake chambers, delivering pressure signals that actuate the foundation brakes. Its specific routing path isolates hydraulic circuits for service and parking brakes, preventing cross-contamination during simultaneous operations. The tube’s pressure stability ensures consistent brake shoe application force across all axles, regardless of load conditions or inclination angles. For fleet operators, this translates to eliminating brake dragging issues that cause premature lining wear. The 190003179785 tubing’s 300% elongation capacity before rupture provides inherent over-pressure protection to expensive ABS modulator units.

Longevity & Maintenance

Field studies demonstrate the 190003179785 tube maintains its original hydraulic performance for over 2.5 million kilometers under normal operating conditions. The ozone-resistant polymer formulation prevents surface cracking in high-UV environments such as mining and desert operations. Unlike rubber hoses that degrade internally from ethanol-based fluid additives, this polyamide tube exhibits zero diameter change after 10,000 thermal cycles. Maintenance protocols specify visual inspections every 150,000km to check for external abrasion at mounting points. Replacement intervals exceed factory service schedules when the OEM 190003179785 part is used in the original application position without modifications.
