Description

The Thermo King 667800 Compressor Oil Filter is a genuine, heavy-duty OEM replacement component engineered specifically to maximize the operational life and efficiency of your transport refrigeration compressor. Designed to capture destructive metal shavings, carbon deposits, and system contaminants, this premium spin-on oil filter prevents premature internal wear on high-stress compressor components. By maintaining optimal oil purity under demanding transport conditions, it plays a vital role in preventing catastrophic reefer system failures and keeping your temperature-sensitive cargo perfectly cooled.

⭐ Key Features & Benefits
  • OEM System Protection: Engineered strictly by Thermo King to match the tight tolerances and pressure requirements of your unit's factory compressor. [1]
  • High-Efficiency Filtration: Traps micro-contaminants and impurities suspended within the compressor lubrication oil to minimize internal friction. [1]
  • Durable Outer Canister: Features a rugged, heavy-gauge steel casing designed to resist vibration, thermal expansion, and intense system pressures over long-haul intervals.
  • Optimized Refrigeration Flow: Prevents lubrication restrictions, ensuring consistent oil delivery to key seals, bearings, and crankshaft surfaces.
  • Extended Equipment Life: Regular replacements with a genuine filter help prevent costly roadside breakdowns and extend the overall lifespan of the compressor group. [1]

🔧 Uses / Applications
  • Trailer & Truck Reefers: Acts as a primary filtration point within a wide assortment of mainstream trailer refrigeration units, including the Thermo King Precedent, SB, SLX, and SLXe series.
  • Medium-Duty Systems: Extends system reliability across truck-mounted transport refrigeration loops like the Thermo King T-Series and MD-Series.
  • Compressor Overhauls: Essential routine maintenance component during seasonal preventative fluid flush intervals or full compressor rebuilds. [1, 2]
