Product Details
This listing covers the Thermo King O-Ring EPDM-161, Thermo King part number 335349. The component uses EPDM rubber formulated to OEM standards for transport refrigeration sealing applications. Install this O-ring in Thermo King refrigeration system sealing points per OEM service procedures to achieve designed reliability and leak control.
Efficiency & Sustainability
EPDM sealing compounds support efficient system operation by maintaining refrigerant and fluid containment, which reduces energy loss and helps sustain consistent temperature control on reefer trailers. Using OEM-specified components supports fleet fuel-efficient cooling strategies and helps maintain compliance in systems such as Smart Reefer SR-4 and Diesel Direct Electric platforms where correct sealing impacts overall system efficiency and emissions profiles, including CARB Evergreen considerations when applicable.
Installation & Maintenance Tips
Install the O-ring with clean, debris-free surfaces and OEM-recommended lubricants where specified. Use Thermo King–approved clamps and retainers for secure fitment. Inspect O-rings during scheduled maintenance intervals and replace at the first sign of hardening, cracking, or extrusion to maintain seal integrity and avoid unscheduled downtime.
Real-World Applications
The Thermo King O-Ring EPDM-161 fits sealing locations across transport refrigeration systems, including hose junctions, valve ports, and pump interfaces on reefer trailers and refrigerated trucks. Technicians at certified dealerships use this part to restore leak-tight performance and protect perishable freight from temperature excursions.
Available for installation and service in Amarillo, Lubbock, Odessa, and throughout West Texas.
