Need help with train horn install

Hi everyone, I need some help.

I have a Viair Ultra Duty 200 PSI air compressor already installed in my truck. I bought a set of horns from Horr Blasters ( and I am wondering if it’s ok to use them with my 200 psi compressor?

Also, all of the fittings that came with my compressor are 1/4", and the fitting on the horns is 1/2". So now I need some sort of T-Fitting that goes 1/4" into the tank, and than splits off of there and goes 1/4" to my air accessory hose, and 1/2" to the horns. Any ideas???

Thanks for any help.

Do a search for the McMaster-Carr pressure regulator. That’ll fix it so you’re not killing the diaphrams in the horns.

Brass NPT fittings can be had from Lowe’s, Home Depot, Ace, Tru-Value, etc., and you can down size to 1/4 inch NPT if needed.
