Description

Maintain the fluid integrity of your transport refrigeration unit's fuel system with the Thermo King Genuine OEM Fuel Pump Valve O-Ring Gasket (Part 332941). Available as a convenient, bulk-savings pack of 4, these factory-original O-rings serve as a precision barrier inside the fuel pump valve assembly, eliminating internal pressure loss and preventing diesel weeping. Molded from an advanced, fuel-resilient elastomer compound, they are specifically optimized to withstand constant chemical exposure from modern diesel blends and extreme high-vibration reefer environments. Keeping this 4-pack on hand ensures fleet technicians can swap these critical seals during routine fuel system maintenance, preventing slow line priming, air intrusion, and costly cargo-spoiling shutdowns.

⭐ Key Features & Benefits
  • Genuine OEM Sealing Multipack: Engineered to exact Thermo King dimensions to prevent minor vacuum leaks or seating gaps common in generic seals.
  • Chemical-Resistant Elastomer: High-durability compound resists swelling, dry-rotting, and degradation from continuous contact with diesel fuels and additives.
  • Pack of 4 Savings: Provides essential service backups for multi-unit fleet maintenance, mobile repair trucks, and parts storage cages.
  • Thermal Cycle Resilience: Formulated to retain its pliable, high-torque sealing memory through extreme temperature shifts from summer heat to deep-freeze operations.
  • Direct Drop-In Fitment: Seamlessly fits original factory groove configurations for an effortless, leak-free installation block.

🔧 Uses / Applications
  • Fuel Pump Valve Resealing: Replaces old, brittle, or flattened O-rings on internal fuel pump plugs, lines, and valve housings across multiple refrigeration units.
  • Yanmar Diesel Engine Maintenance: Fully compatible with TK482, TK486, TK486E, and TK486V engine families powering transport refrigeration lines.
  • High-Capacity Trailer Service: Fits a wide selection of popular Thermo King trailer platforms, including SB-200, SB-210, SB-230, SB-310, SB-330, Super-2, and SLX 400 models.
  • Preventative Fleet Tuning: Crucial, budget-friendly seal replacement pack to include during primary fuel system rebuilds or general fleet overhauls.
