Product Overview
The Sealco 99600B is a high-quality, automatic push–pull valve designed for dashboard control in truck and tractor air brake systems. This panel-mounted valve automatically shuts off when system pressure drops below 30 PSI ±5, helping to prevent air loss and maintain system integrity. It mounts neatly on dash panels with its standard faceplate and includes a durable control knob for reliable performance in harsh fleet environments.
