Product Details
The Thermo King SOC HD Pressure Plug 550433 serves as a pressure-retaining plug for Thermo King transport refrigeration systems. Specific material composition and numerical pressure ratings follow Thermo King OEM specifications and application guidance. This component integrates with Thermo King assemblies and supports consistent system operation on models including Precedent S-610M, S-610DE, Smart Reefer SR-4 monitored systems, and Diesel Direct Electric configurations where OEM plug fitment is required. For exact fitment by unit serial number and service bulletin cross-reference, consult West Texas Thermo King parts specialists.
Efficiency & Sustainability
This Thermo King part helps maintain proper refrigerant circuit integrity, which contributes to consistent temperature control and more efficient cooling cycles. Proper sealing reduces refrigerant loss and supports compliance goals for transport refrigeration fleets. Integration with Smart Reefer SR-4 telemetry and CARB Evergreen‑compliant systems enhances monitoring, reduces unnecessary run time, and supports sustainable fleet operations across West Texas and the Permian Basin.
Installation & Maintenance Tips
Use OEM-specified tools and clamps for secure fitment. Inspect the plug during scheduled preventive maintenance intervals and whenever a refrigeration circuit opens for service. Replace if signs of wear, deformation, or seal compromise appear. For installation assistance, unit-specific torque and installation guidance are available through West Texas Thermo King certified technicians.
