Air System Parts
The air system is the hardest-working system on a yard truck — it runs the brakes, the cab suspension, and the trailer connection. We stock 180+ air-system parts across Kalmar Ottawa, Capacity, Autocar, and Automann: yellow park-brake and red emergency valves, cab air springs, gladhands and gladhand seals, drain valves, and air dryers. These are the most-reordered parts on working trucks — fleets on preventive-maintenance cycles keep them on the shelf.
Air System Parts FAQ
Which valve is the yellow knob and which is the red one?
On Kalmar Ottawa dashes the yellow knob is the parking-brake valve (90007281) and the red knob is the emergency/trailer-supply valve (90007283). We stock both, along with the dash panels and hardware around them.
Do you carry gladhands and gladhand seals?
Yes — gladhands and gladhand seals (the seal, part 10028, is one of the cheapest and most frequently ordered parts in the catalog). Worn gladhand seals are the first thing to check on a slow trailer-air leak.
