3/8″ NTP Male-Threaded Adjustable Brass Nozzle, 5/16″ OD x 7/32″ ID
Most commonly used in smaller fountain spray rings, this level independent nozzle has its jet above the surface of the water. If the water level drops, the water stream is unaffected. The water stream is typically less turbulent with this type of brass nozzles requiring less pump power. The pattern with this type of nozzle is defined by the jet orientation and not surface wave action within the pool. These nozzles are better for large interactive fountains as well as fountain applications requiring a precise stream of water such as spitting fountains.
- Adjustable Nozzles are sold as a set (as both the bottom male NPT threaded portion and the top friction fit nozzle which has a finer thread pattern and is meant to be finger tight).
- Please do not assume that if you have the bottom portion already welded into your copper ring (and only really need the top portion), that it will be the same thread pattern as the female end of the existing part you already have.
- Here is our return policy if the nozzle does not actually fit your existing part and you need to return it within 30 days. Please see sizing information below.
Pipe thread sizes do NOT refer to any physical dimension. The outside diameter of each nozzle must be measured and compared to Table 1.1 for correct size identification. For example, a 1/4” NPT nozzle has an outside thread diameter of 0.540”
