U CUP - American Forge & Foundry

Part #: 359645

The American Forge & Foundry (AFF) 359645 U CUP is a vital sealing component engineered for professional-grade automotive and industrial hydraulic and pneumatic systems. This high-quality service part ensures reliable leak prevention and helps maintain optimal system pressure, crucial for the efficient and safe operation of heavy-duty equipment. Constructed from durable sealing material, it provides a robust barrier against fluid leakage and contamination.

Key Features

  • Pressure-Energized Sealing: Designed with a U-shaped profile, this seal utilizes system pressure to energize its lips, increasing sealing force as pressure builds for a more secure and responsive seal in dynamic applications.
  • Durable Construction: Manufactured to withstand rigorous demands, the U CUP offers exceptional resistance to wear and abrasion, contributing to a longer service life and reduced maintenance frequency.
  • Effective Dynamic & Static Performance: Suitable for both moving (dynamic) and stationary (static) applications, ensuring consistent sealing integrity across various operating conditions.
  • Contamination Protection: Acts as a critical barrier to protect internal components from dirt, debris, and external contaminants, preserving the longevity and performance of your hydraulic and pneumatic systems.
  • Broad Fluid and Temperature Compatibility: Crafted from materials typically resistant to a wide range of hydraulic fluids and varying temperatures, ensuring reliable operation in diverse professional environments.

Applications

The AFF 359645 U CUP is essential for maintaining the operational integrity of a wide array of professional tools and machinery. Specifically, it serves as a piston cup for the American Forge & Foundry Model #3596, a 5-1/2 Ton Long-Reach Air Lift. Beyond this specific application, U-cup seals are broadly utilized in hydraulic cylinders, valves, and pumps across the automotive industry, including vehicle lifts and floor jacks. In industrial settings, they are indispensable in heavy equipment, pneumatic actuators, presses, and other fluid power systems where dependable sealing is paramount.
