Rolair JC800-48 Four Port Air Pressure Switch

Rolair JC800-48 Four-Port Pressure Switch acts as the auto-start/stop controller for the Rolair JC10 portable air compressor. This four-port switch carries a 95 psi cut-in (on) and 125 psi cut-out (off) setting to regulate air delivery across the JC10’s four-port manifold. It uses four 1/4-inch port connections with female threads (1/4" FPT) to integrate with standard Rolair piping and the JC10’s distribution layout. Rolair’s parts pricing documentation lists JC800-48 as superseded by the U6005 pressure switch, indicating a newer replacement part is available while the JC800-48 remains referenced as a JC10-compatible four-port switch in catalogs. As a common replacement part, the JC800-48 is frequently stocked by distributors and retailers for JC10 maintenance or upgrades, preserving the familiar 95/125 psi cycling and four-port arrangement that supports reliable automatic starting and stopping of the compressor. It is designed to work with Rolair’s JC10 system, enabling straightforward installation in typical workshop or field service scenarios where reliable regulated air delivery is required.
