An embossed letter 'H' on an air valve core stem indicates?

High-pressure type
Helium-filled type
Heavy-duty type
High-temperature type

The correct answer is: High-pressure type

An embossed letter 'H' on an air valve core stem indicates that it is a high-pressure type. This means that it is designed to withstand higher levels of pressure than other types of valve cores. Option B, Helium-filled type, is incorrect because helium-filled valves would usually have an 'He' or 'HE' embossed on them. Option C, Heavy-duty type, is incorrect because valve cores can be heavy duty without having an 'H' embossed on them. Finally, option D, High-temperature type, is incorrect because high-temperature valve cores would usually have a 'HT' or 'HI' embossed on them. It is important to pay attention to these embossed letters as they provide important information about the type and capabilities of the valve core.
