Product Details
The Thermo King Plug 551952 is an OEM-grade electrical plug intended for use with Thermo King transport refrigeration equipment. It features industry-standard materials and finishes selected to withstand thermal cycling and the rigors of refrigerated transport. For exact application guidance and fitment confirmation for specific Thermo King platforms such as Precedent series, Smart Reefer SR-4, or Diesel Direct Electric models, consult parts documentation or certified service personnel.
Efficiency & Sustainability
This plug supports reliable operation of fuel-efficient cooling systems and precision temperature control that reduce cycle irregularities and compressor runtime. Proper electrical connections contribute to overall system efficiency and help maintain compliance with fleet emission and efficiency programs such as CARB Evergreen when applied within certified Thermo King configurations.
Installation & Maintenance Tips
Use OEM-grade clamps and seals for secure fitment and inspect connections during scheduled maintenance intervals. Verify contact cleanliness and torque values where required, and replace the plug at first sign of corrosion, cracking, or intermittent connection to protect sensitive control electronics.
Real-World Applications
The Thermo King Plug 551952 is ideal for reefer trailers, refrigerated straight trucks, and tractor-mounted refrigeration units used in cross-regional transport across Amarillo, Lubbock, Odessa, and the wider West Texas corridor. It supports temperature-critical loads such as food, pharmaceuticals, and other perishable cargo where consistent temperature control is essential.
