About this item
The Thermo King Shaft Seal LS is a precision-engineered replacement seal designed for long-service Thermo King refrigeration compressors. Manufactured to OEM tolerances, it delivers a leak-tight rotating shaft interface that protects refrigerant charge, oil pressure, and compressor longevity. Ideal for fleet operators looking to reduce downtime and extend reefer service intervals.
Every thermo king shaft seal ls is sourced, inspected, and serviced by our in-house technicians at our Long Beach depot before it leaves the yard. We've been supplying thermo king parts to contractors, fleet operators, farmers, developers, and small businesses across North America for over a decade — so you can buy with confidence knowing the unit you receive matches exactly what you ordered.
Pricing reflects the unit only; freight to your job site is quoted separately based on your delivery zip code, site accessibility, and any crane or specialty equipment required for offload.
