Product Overview
The Sealco 17620 is a panel-mounted manual push–pull valve used principally for controlling the inflation or deflation of air suspension bags—or for quick trailer or dolly park brake release without re-pressurizing. With a 7/8″ threaded panel mount and generous ¼″ NPT inlet, outlet, and exhaust ports, it’s a simple, durable solution for in-cab pneumatic control. Built to OEM-grade specifications, this valve delivers reliable performance across vocational trucking and trailer applications.
