Hey everyone, it’s been a while since I posted. Finally ready to install my 240 kit on my 1996 land rover discovery. However I do take this vehicle offroading. It has a 2" lift and big tires, but I still worry about the horns getting damaged (or stolen). What kind of fittings can I use to quickly disconnect each horn from it’s air hose individually?
How often would you unhook them?
The fittings that come with the kit are push-to-connect. The have a release ring that you press and then pull the tube out.
I don’t know if the tolerate a lot of assembly/disassembly though.
The easiest solution would be to:
- Install a 1/2" female quick disconnect coupler on the output side of the solenoid
- Add a 1/2" male quick disconnect nipple (and hose, as needed) to the manifold
- Mount manifold and all plumbing to the bells on something easily removed but also easily locked into place in your chosen location
This would allow you to:
- Easily disconnect the manifold from the solenoid
- Unlock your mounted horns w/manifold and take them on the go
I’m forced to ask, though – is there no room behind the grille of your Land Rover Discovery to mount the bells facing straight down? It seems like that mount location would solve all of your problems without any need to remove things, as theft would be a real PITA and the likelihood of damage is, well, about as likely as you are to ram the front end into something.
That’s what I’m wondering too. Big 4x4 like that…Check the install galleries for some ideas. If you can hide them in a Smart, surely you can find a spot on the Discovery.
Quick connect couplers can be notorious for having leaks.
Dan brings up one more reason to look for a permanent mounting location/solution that addresses the breakage/theft concerns without use of QD couplers - QD couplers are absolutely prone to leakage after they are weathered a bit in brine/salt/sand/mud/etc.
A higher quality coupler and use of a dust/debris cover (when the nipple is not inserted in the coupler, of course) will go a long way to avoiding leaks, but it’s no silver bullet.
As an example, I’m going almost a year with no leaks on both of the QD couplers on my system (one at the front of the truck near the winch … and one on the aft end … both of which are decent quality and protected by dust/debris covers). Mine are there specifically for air tool use. Of course, if one leaks I’ll just change it out since it’s quick/easy, and I keep spares around precisely because of Dan’s concern. 
The QD coupler might leak a smidge during honking, but it wouldn’t be under constant pressure if you mount it between the valve & horns. I would be more concerned about flow rates.
Good point, most of them would restrict air flow.
Absolutely true – but probably not enough to make a substantive difference if a 1/2" coupler and nipple were used, as suggested. 1/4" and 3/8" would be right out.
I agree. I’ve blown the RS5 through a 1/2" quick coupler and it was still epic. I reckon it was the closest I’ve ever come to generating the mystical “brown note” 
DeeBee, what’s a “brown note?”
That’s been around for some time but this is the first time I heard it had a name.
Mythbusters did a brown note episode.
Busted! lol
South Park did a show about it, too, but they called it the ‘brown noise’.

Thank you, I am now up to speed and wish I never asked now! Lol
