Our brass horn valve is threaded 10-1mm to accept our pouring spout, or our calibrated charger spouts to dispense measured charges of black powder directly from a horn. Use our #HVB, small bushing, to simplify installation of the valve. The bushing can be epoxy glued into the horn tip, providing a strong 3/8-24 thread. Our threaded brass flask filling funnel fits the valve too, allowing easy refill of your horn.
