Description

Overview

Radiator Cap Carrier Supra 0.7 Lbs is a cooling system service cap for selected Carrier Supra and Ultra transport refrigeration applications. It is used where the existing cap no longer seals correctly or no longer holds the listed pressure rating. Because radiator cap condition affects coolant control, this replacement helps maintain proper cooling system operation during normal reefer service.

Features

• Cooling system radiator cap for selected Carrier refrigeration units
• Source listing identifies a 0.7 Lbs pressure rating
• Compact service item that is quick to inspect and replace
• Suitable for routine cooling system maintenance work

Compatibility and Fitment

Check the existing cap style and application before ordering, because Carrier used several cooling layouts across Supra and Ultra families. The source listing names Supra 550, 750, 850, 950, 950MT, 1050, 1150, 1250 and Ultra applications, so this cap suits those published model groups where the installed cap matches. This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. 30-60041-01SV, 306004101SV, 30-60041-01, 306004101, 30-60041-00, 306004100, 42-60042-00, 426004200

Compliance and Safety

Only fit the cap to a cold system, because removing a hot cooling cap can release pressure and coolant suddenly. Inspect the filler neck and seal faces before installation, and replace any damaged neck or gasket surfaces at the same time. If the cooling system has been losing coolant, pressure-test the system and check hose, radiator and water pump condition as well.

Trailer Applications

Radiator Cap Carrier Supra 0.7 Lbs suits refrigerated trailer fleets running compatible Carrier Supra and Ultra equipment. It is a practical maintenance item during coolant service, leak diagnosis or preventive inspections, especially when the original cap shows seal wear, spring fatigue or visible corrosion around the locking tabs.
