What is an Air Chuck?
These are valve fittings used to connect directly to your tire valve stem, and their purpose is to inflate tires. Air chucks allow for free airflow to and from the tire for pressure inflation and maintenance.
Open Flow Air Chuck vs. Closed Flow Air Chucks
● Open flow air chucks will allow air a constant flow of air provided the compressor is running. These chucks provide a modern way of using air chucks as they allow you to use the tool with tire inflator gauges like the Diamond-U 900LW, letting you monitor pressure levels while filling the tire.
● Closed flow air chucks connect directly to the air compressor hoses and let air move from the compressor straight into the tire but only when engaged with the tire valve stem.
