Running Air Line the the Horns
It is very important to turn off all compressors and drain the tanks before you start connecting the horns. Before
cutting any air tubing, make sure to double check your measurements. Make sure to cut equal lengths of air line to connect
each horn to the manifold or the horns may sound at different times. We recommend cutting your lengths with at least an
extra inch per line just to be safe. Unlike compression fittings, the push to pull connectors can be used multiple times. The air
valve should connect to the center fitting of the 4-point banjo fitting. When threading any fittings make sure to use Teflon
tape or lock-tight to prevent air leaks. Some fittings may already have pipe sealant applied on their threads for your conve-
nience. The air valve may be mounted in any direction but it is preferred that it is mounted vertically.
Air Horns to Tank:
[Air Tank] » [1/2” NPT M to 1/2” PTC Fitting] » [1/2” Air Line] » [1/2” NPT M to 1/2” PTC Fitting] » [Air Valve] » [1/2” to 4x
5/16” NPT M Banjo Fitting] » [5/16” Air Line] » [5/16in P2P to 1/8in NPT F Elbow] » [Rear Horn Mount]
1. Plan out the fittings placement before you begin and make sure you understand the correct order.
2. Make sure that your tank is empty of air and that the compressor is not running during installation.
3. Start by cutting equal lengths of 5/16” tubing to run from each horn to the banjo fitting.
4. Install your banjo fitting into the outlet port of your 1/2” air valve. If the valve has a directional arrow on its body, the
arrow starts with the inlet and points out the outlet; the arrow should point towards your horns.
5. Plumb each horn to the banjo fitting, making sure that the lines are inserted firmly into their sockets. You do not use
Teflon tape or pipe sealant with the PVC fittings.
6. Finally connect your air valves inlet port to your air tank using 1/2” air line using the 1/2” M NPT to 1/2” PTC fittings. Make
sure to use a side or top port on your tank so that condensation will not drain in to your air valve.
Finishing Up
The final step is testing your installation! Turn you air system back on and once the tank is full, check for air leaks on the fittings
throughout the whole system. If you see any problems, re-plumb those fittings as you deem neccessary. You’re almost done!
