Product Details

The Thermo King Service Valve Cap, Plastic 662296 is an OEM protective cap designed for Thermo King service valve ports. The cap uses thermoplastic material specified for service-port protection and field durability.

Installation & Maintenance Tips

Install the cap by hand-tightening onto the service valve port until secure; avoid over-torquing. Inspect caps during scheduled service intervals and replace if cracked, missing, or compromised. Use OEM-recommended fittings and seals when performing valve service to maintain leak-free connections and safe refrigerant handling.

Real-World Applications

This service valve cap fits typical applications across transport refrigeration, including reefer trailers and refrigerated trucks operating in the Permian Basin and across West Texas. It performs as a preventive accessory in routine maintenance, roadside service, and depot inspections to protect valve access points used for charging and diagnostics.
