Description
Fire Hose Fog Nozzle, Adjustable Straight Stream to Fog, Twist Shutoff, 150 PSI, Wildland Firefighting Compatible
Thermoplastic Fog Nozzle Overview
Building codes require fog nozzles on hose rack and reel systems in commercial and industrial buildings. Wildland firefighting crews also run them on forestry lines in the field. This thermoplastic fog nozzle threads onto NPSH fire hose in four sizes and adjusts from straight stream to fog with a twist. Each fire hose fog nozzle handles up to 150 PSI.

Key Features
Adjustable Straight Stream, Fog, and Full Shutoff
Twist the nozzle body to move between a focused straight stream, a wide fog pattern, and complete shutoff. This adjustable fog nozzle gives the operator spray pattern and flow control from a single fitting without disconnecting from the hose.
NPSH Female Thread in Four Sizes
The NPSH fog nozzle threads directly onto any male NPSH hose coupling, standpipe outlet, or swivel adapter. Wildland crews often thread a quick-connect forestry adapter into the 3/4", 1", and 1-1/2" sizes to run them on forestry hose lines.
150 PSI Pressure Rating
A 150 PSI fire hose nozzle handles the pressure range of most building fire suppression systems. Many competing nozzle models carry only a 100 PSI rating, limiting their margin during pressure spikes.
ULC Listed and FM Approved (1-1/2")
The 1-1/2" G97-150 is a ULC listed fire hose nozzle with FM approval, meeting procurement standards for fire departments, commercial insurers, and building inspectors across North America. The 3/4", 1", and 2" nozzles do not carry these listings.
Rubber Bumper Guard
A rubber bumper guard on the intake end of this plastic fire hose nozzle absorbs impacts during hose reel rewind, protecting both threads and the reel cradle. The guard makes it a practical fog nozzle for hose rack installations where the nozzle contacts metal on every retraction.
Fire Hose Nozzle Thread Types: NPSH vs NST vs GHT
Matching the nozzle thread to the hose thread eliminates adapters and leak points. Understanding fire hose nozzle thread types helps buyers order the right nozzle the first time.
NPSH (National Pipe Straight Hose)
The standard for commercial and industrial fire hose systems, hose rack installations, and building fire suppression. NPSH threads are straight (non-tapered) and sealed with a rubber gasket. The G97 nozzle line uses NPSH threads in all four sizes. The 3/4", 1", and 1-1/2" sizes also see use in wildland firefighting when adapted to forestry hose connections.
NST / NH (National Standard Thread)
The municipal fire service standard is found on fire hydrants, pumper outlets, and municipal fire hoses. NST threads are not compatible with NPSH without an adapter. Buyers equipping a municipal apparatus should confirm whether their hose uses NST or NPSH before ordering.
GHT (Garden Hose Thread)Standard garden hose connections for residential use. GHT nozzles are
smaller, lower pressure, and not rated for fire suppression or industrial washdown.
For hose rack and reel systems in commercial buildings, NPSH is almost always the correct thread type.
Applications
- Hose rack and reel assemblies in commercial and industrial buildings where a fire hose nozzle with shutoff controls flow at the nozzle end
- Industrial washdown and equipment cleaning: fire hose fog nozzle for daily rinse-down on NPSH water lines
- Manufacturing facilities, warehouses, and refineries with fixed NPSH fire suppression hose connections
- Construction sites and temporary water supply where a lightweight fire hose nozzle keeps the end of the line manageable
- Wildland firefighting crews threading a forestry quick-connect adapter onto the 3/4", 1", or 1-1/2" industrial fire hose nozzle for use on forestry hose lines

Frequently Asked Questions
What spray patterns does this thermoplastic fog nozzle produce?
The nozzle twists between a focused straight stream, a wide fog pattern, and full shutoff. Operators can change patterns during use without disconnecting from the hose coupling or interrupting flow.
What thread type do these nozzles use?
All four sizes use Female Pipe (NPSH) threads, the standard thread for industrial and commercial fire hose systems. The NPSH fog nozzle fits any male NPSH coupling, standpipe outlet, or swivel fitting.
Does the nozzle fully stop water flow?
The twist shutoff position closes completely and stops flow. A fire hose nozzle with shutoff at the nozzle end lets the operator pause during pattern changes or when repositioning the hose without shutting down the supply.
Is this an adjustable fog nozzle or fixed pattern?
This is a fully adjustable fog nozzle with three positions: straight stream, fog, and shutoff. The twist body lets the operator move between all three patterns from a single nozzle.
Can I use these nozzles on wildland forestry hose?
The 3/4", 1", and 1-1/2" sizes work on wildland forestry lines when a quick-connect forestry adapter is threaded into the NPSH inlet. The 2" is not commonly used in wildland applications. This industrial fire hose nozzle pairs well with lightweight single jacket forestry hose for brush and structure protection work.
