ASM F1 hoses (high pressure side)

The ASM F1 High-Pressure Hose Kit is a direct replacement for all the high-pressure hoses in the F1 gearbox, designed to address the known failure points of the factory-installed hoses. Unlike the original braided hoses, which are prone to failure over time due to crimping, chafing against upper frame mounts, or twisting during servicing, our kit offers an upgraded solution with Teflon-lined hoses and advanced anti-twist stress relievers. This kit not only matches the hydraulic specifications of the original hoses but also improves upon them, offering a more durable, cost-effective, and reliable alternative.

Key Features:

• Upgraded Hose Construction: The hoses in this kit are designed with Teflon liners for superior chemical and thermal resistance. The Teflon lining minimizes internal friction, ensuring consistent fluid flow under high-pressure conditions, while enhancing durability against wear, heat, and pressure fluctuations.
• Precise Internal Diameter & Fittings: Each hose is built with the exact internal diameters and fitting specifications required for the F1 gearbox, ensuring seamless compatibility and maintaining the precise hydraulic characteristics of the factory hoses. The specially engineered fittings and banjo connectors ensure optimal fluid flow and pressure management, essential for maintaining shift performance in high-stress F1 applications.
• Hydraulic Performance: The hoses are designed to support high-pressure operation:
  • In the 4700 transmission, the hoses enable 60ms shift times at 80 bar pressure.
  • In the 4200 transmission, they support 100ms shift times at 50 bar pressure, meeting the hydraulic requirements for high-speed gear shifting in F1 transmissions.
  • High temperature Resistance over 250c, the lines pass next to the left bank exhaust 
• Anti-Twist Stress Relief: To prevent the common issue of hose twisting during installation and servicing, the EVO 2 version of our kit incorporates stress relief points at the hose ends. These relief points mitigate the risk of twisting, chafing, or damage caused by the movement of the gearbox or incorrect routing.
• Superior Durability: In addition to the Teflon lining, the hoses are reinforced with high-strength braiding and material composition that offers exceptional resistance to abrasion, pressure fatigue, and physical wear, ensuring a longer lifespan than the original factory hoses.
• Cost-Effective Alternative: Our hose kit offers a high-performance replacement at a fraction of the cost of the OEM hoses, with numerous design upgrades that enhance the durability and reliability of your F1 gearbox.

Benefits:

• Enhanced Reliability: The Teflon lining, stress relief features, and reinforced construction prevent common hose failure modes, ensuring consistent and reliable gearbox operation under high pressures.
• Improved Performance: By maintaining optimal fluid flow and pressure characteristics, this kit helps ensure fast, responsive gear shifts—essential for maintaining peak F1 transmission performance.
• Increased Longevity: With added protection against heat, abrasion, and twisting, the upgraded hoses in this kit provide longer-lasting performance, reducing the need for frequent replacements.
• Easy Installation: The hoses are designed for a direct replacement, offering simple installation with no modifications required to the gearbox or fittings.

Compatibility:

• F1 Gearbox Systems – Compatible with 4700 and 4200 series F1 transmissions, providing a performance and durability upgrade for any F1-equipped Maserati model.

With the ASM F1 High-Pressure Hose Kit, you get a superior, long-lasting replacement that not only matches the hydraulic specs of the factory hoses but improves upon them with advanced materials and design. Upgrade your F1 gearbox system with a more reliable, cost-effective solution that will deliver consistent, high-performance shifting under the most demanding conditions
