Color-coded blue for use on the left side, the aluminum air connector includes a rubber grommet for an airtight seal. The female thread couples seamlessly with EZC3N1 and meets or exceeds SAE J318 standards. EZ Claw recommends carrying this spare in the cab of the semi for an in-the-field replacement and also recommends the use of thread tape for a tight seal on the hose end connection. SAE standards ensure the gladhand is DOT compliant.
