R5494 Serrated Ball Air Chucks

Built for 5/16-inch hose setups rather than the more common 1/4-inch fitting, the R5494 combines a ball-type seal with a serrated shank designed to grip the hose securely and resist slipping under pressure.

The serrated barb bites into the hose material as it's clamped or crimped in place, creating a connection that holds firm even as the hose flexes and moves during regular shop use.

This size makes the R5494 a fit for equipment and setups standardized on 5/16-inch lines, giving those shops a reliable ball-type chuck option without needing to adapt down to a 1/4-inch fitting.
