Product Description
The Demco 17464 is a replacement push-lock T-fitting used when installing the Demco Air Force One supplemental braking system on a Freightliner Super C chassis. The T-fitting taps into the motorhome's air line to supply air to the Air Force One system, which applies the towed vehicle's brakes in proportion to the coach's braking.
This listing is for one fitting. It installs in about 15 minutes.

Pro tipSupplemental braking: what to know
- Often required by law. Most U.S. states and Canadian provinces require brakes on a towed vehicle above a certain weight, and towing equipment makers generally expect one.
- Match your motorhome. Some systems are designed for coaches with air brakes and others for hydraulic brakes — check which your RV has.
- Portable vs. permanently installed. Portable units move between cars; installed systems are quicker to hook up day to day.
