Description

Overview

Expansion Tank Cap 15psi Thermo King T-Series Precedent is a replacement cooling system cap for compatible transport refrigeration applications. It suits Precedent units and selected Thermo King T-Series applications where a 15psi pressure cap is specified. Because cooling system pressure can vary by model, buyers should match the cap rating, neck style, and existing fitted cap before ordering.

Features

• Replacement expansion tank cap for compatible Thermo King cooling systems
• 15psi pressure rating for matching applications
• Useful for routine coolant system servicing and cap replacement
• Suitable for workshop, fleet, and owner-operator maintenance on compatible units

Compatibility and Fitment

This cap suits compatible Thermo King Precedent units and selected T-Series applications where a 15psi expansion tank cap is specified. However, some T-Series variants use different cap pressures, so the safest check is to match the rating and existing cap before fitting. This part is a suitable replacement for the part numbers and matching applications shown. Some changes in installation may be required. TK-13-0990, TK130990, 13-0990, 130990, 13-990, 13990

Compliance and Safety

Do not remove the expansion tank cap while coolant is hot, because the cooling system can remain under pressure after operation. Let the unit cool fully before inspection or replacement. Also check the sealing faces and cap seat during service, because a damaged neck or contaminated surface can still cause leaks. If the cooling system continues to lose pressure, inspect the tank, hoses, and related cooling components before returning the unit to service.

Trailer Applications

Expansion Tank Cap 15psi Thermo King T-Series Precedent suits refrigerated trailer service work where the unit uses a compatible 15psi cooling system cap. It works well during preventive maintenance, and it also helps restore correct cooling system pressure after a worn or damaged cap has been removed. As a result, workshops can use this part for straightforward replacement on matching transport refrigeration units.
