Description
A Smooth Bore Fire Nozzle in Lightweight Plastic
Product Overview
This is a one-piece red plastic fire hose nozzle that threads onto a 1-1/2" NPSH male coupling and delivers a fixed straight stream. There is no shut-off and no spray adjustment. The bore tapers from the thread to the tip, which accelerates the water into a single driven stream. It weighs 1.00 lb, less than half the weight of the brass version in the same size, and costs a fraction of the price.
Key Features and Benefits
- One-piece red thermoplastic body with no moving parts.
- Female 1-1/2" NPSH thread spins onto any 1-1/2" male NPSH coupling or hose assembly by hand.
- 3/8" orifice shapes the flow into a tight, straight stream.
- 7" overall length.
- Rated for use up to 100 PSI.
- 1.00 lb. The brass 1-1/2" tapered nozzle weighs 2.13 lb.
- Red color stands out against hose and equipment for quick identification.
Applications
- Fire standby lines. A straight-stream nozzle for standpipe cabinets, fire points, and basic fire standby setups on 1-1/2" NPSH hose.
- Forestry and rural supply lines. A lightweight tip that adds minimal weight to a crew pack or truck compartment.
- Washdown. A fixed stream for cleaning floors, equipment, and outdoor areas on 1-1/2" hose lines.
There is no shut-off on this nozzle. Control the flow at the supply valve or hydrant. For spray pattern control at the tip, choose a combination fog nozzle instead.
Plastic or Brass?
Both tapered nozzles thread onto 1-1/2" NPSH hose lines and produce the same straight-stream output.
- Red thermoplastic tapered nozzle (this product). Lighter and lower cost. 1.00 lb. Available in 1-1/2" NPSH only.
- Solid brass tapered nozzles. Heavier, more corrosion-resistant, and available in five sizes from garden hose thread to 1-1/2" NPSH. Choose brass when you need a different thread size or when long-term corrosion resistance matters more than weight.

Frequently Asked Questions
What is a smooth bore fire nozzle?
A smooth bore fire nozzle is a one-piece tip with a fixed opening that delivers a single straight stream. "Smooth bore" and "tapered nozzle" describe the same design: the bore narrows from the hose thread to the outlet, and there are no moving parts, no spray patterns, and no shut-off.
What is the difference between a smooth bore nozzle and a combination nozzle?
A smooth bore nozzle produces a single concentrated stream. A combination nozzle has a built-in shut-off and rotates between a focused jet and a wide fog spray. Choose smooth bore for simplicity and a solid stream. Choose a combination for pattern control and shut-off at the tip.
Is a plastic fire nozzle as durable as brass?
Plastic is lighter and less expensive but not as resistant to corrosion or long-term wear as brass. For a nozzle that stays on a standpipe cabinet or a fire standby line and sees occasional use, thermoplastic holds up well. For heavy daily washdown service or permanent outdoor exposure, brass is the more durable choice.
Will this nozzle fit my fire hose?
It fits any hose or coupling with a 1-1/2" male NPSH thread. That includes 1-1/2" NPSH hose assemblies and hose lines built with 1-1/2" NPSH male couplings. It does not fit NH/NST fire hose threads or NPT pipe threads, which are different thread standards.
