Product Details
The Thermo King O Ring 331491 is an OEM Thermo King sealing component specified for use in Thermo King transport refrigeration units. This O Ring performs as a critical sealing element in refrigeration circuits and component interfaces where a reliable, repeatable seal is required. Product documentation and parts catalogs list the part number for direct-fit replacement; for model-specific fitment and placement within Smart Reefer, Precedent, or Diesel Direct Electric systems, consult system schematics or certified service literature.
Efficiency & Sustainability
This O Ring supports efficient, fuel-conscious cooling by preserving refrigerant charge and preventing leaks that compromise temperature control. Proper sealing reduces system cycling and energy waste, contributing to overall fleet efficiency. Parts compliance and application across modern Thermo King platforms, including systems that integrate Smart Reefer SR-4 telematics or CARB Evergreen strategies, help maintain regulatory and operational goals for refrigerated transport.
Installation & Maintenance Tips
Use OEM clamps and specified lubricants for secure fitment and to prevent abrasion during installation. Inspect O Rings during scheduled maintenance intervals and whenever a system is opened for service. Replace any O Ring showing wear, deformation, or loss of elasticity to preserve temperature control reliability and minimize unscheduled downtime.
Real-World Applications
The Thermo King O Ring 331491 is ideal for reefer trailers, refrigerated straight trucks, and other transport refrigeration systems that require dependable seals under frequent temperature cycling and road vibration. Fleets operating in Amarillo, Lubbock, Odessa, and throughout the Permian Basin rely on certified parts to protect perishable loads and maintain regulatory temperature control.
