Description
The Ready-to-Connect Fire Hose with NPSH Couplings
Product Overview
A coil of bare hose needs couplings, clamps, and assembly time before it can move water. A single jacket fire hose assembly skips that setup: 50 or 100 feet of white single jacket hose with a hard-coat aluminum NPSH coupling already on each end, one male end, one female swivel end, rated 150 PSI and ready to connect to a pump, standpipe, or forestry wye.
Key Features and Benefits
- Each length carries a male NPSH thread on one end and a female NPSH swivel on the other, so one assembly connects the pump to discharge on its own, and two assemblies join end to end when the run needs more reach.
- The female swivel spins the coupling nut instead of the hose, so connections tighten by hand without twisting the line.
- The single jacket is woven from 100% synthetic fabric over a black rubber tube and resists mildew and rot, so the hose can be stored coiled in a cabinet or truck box between uses.
- Rated for 150 PSI working pressure with a 300 PSI test pressure, the same rating as the bulk hose it is built from.
- Hard-coat aluminum fittings carry a hardened, corrosion-resistant surface. NPSH is one of the two standard ends on 1-1/2" fire hose in Canada, alongside the quarter-turn forestry coupling, so the threads mate with pumps, wyes, and adapters already in service.
Pick a Length
Both lengths run the same hose and the same fittings; the choice is how much reach you need versus how much coil you carry.
| Part Number | Length | Working / Test Pressure | Weight (Coupled) |
|---|---|---|---|
| G1921-150NP50 | 50 ft | 150 / 300 PSI | 9 lb |
| G1921-150NP100 | 100 ft | 150 / 300 PSI | 17 lb |
Which 1-1/2" Fire Hose Assembly Do You Need?
The same hose leaves the factory with three different ends, and a double-jacket version exists for rough handling. A single-jacket fire hose assembly with aluminum NPSH ends is the standard threaded configuration for stationary lines on pumps, standpipes, and NPSH-threaded systems; here is when one of the others fits better.
- Brass NPSH swivels: The same single jacket hose with brass ends instead of aluminum, for lines and systems that already run brass fittings.
- Forestry instantaneous fittings: Quarter-turn quick-connect ends with no male or female side, for wildland and forestry crews coupling lines fast in the field.
- Double jacket with aluminum NPSH: A second woven jacket over the same construction, for hose that gets dragged, re-laid, or handled rough on every job.
Applications
- Fire standby and mill protection. Staged at stations, hung in hose cabinets, and connected to standpipes, ready to deploy.
- Forestry water delivery. A fire hose with NPSH couplings drops straight into existing pump lines beside wyes, valves, and adapters.
- Pump dewatering and washdowns. Handles discharge duty up to its 150 PSI working rating and stores fine even when put away damp.
- Building your own lines instead. Buy single jacket hose by the foot and add couplings, or skip the work with this pre-assembled line.
One honest limit: single jacket hose is stationary-duty equipment. It should not be dragged repeatedly or exposed to rough environments. Lines that get hauled and re-laid on every job belong in the double jacket version above.

Frequently Asked Questions
What is a single jacket fire hose assembly?
A hose with one woven synthetic jacket over a rubber tube, sold with couplings already installed on both ends. The single jacket keeps it light for its pressure rating, and the factory-fitted ends mean there are no shank couplings or clamps to install.
Will NPSH couplings connect to a fire hydrant?
Only if the outlet is NPSH. Canadian hydrants usually carry regional hydrant threads on their ports, so hose lines connect through an adapter instead. US buyers should check threads too: 1-1/2" equipment there normally runs NST, also called NH, which does not mate with NPSH.
Can a single jacket fire hose be dragged?
Not repeatedly. The manufacturer states that single-jacket hose should not be dragged over and over or exposed to rough environments. Stage it, hang it, or lay it once per job. Hose that gets pulled across the ground on every use belongs in a double jacket.
Should I choose aluminum or brass fire hose couplings?
Both versions carry the same hose and the same NPSH threads, so they connect identically. Hard-coat aluminum wears a hardened, corrosion-resistant finish and is the standard configuration. Brass suits crews matching lines that already run brass fittings.
How much does a fire hose assembly weigh?
With couplings on, the 50 ft assembly weighs 9 lb and the 100 ft assembly weighs 17 lb. The bare hose runs 0.16 lb per foot. One person can carry either length to a standpipe or pump without help.
