Quick verdict
A rotary turbo nozzle rated to 4500 PSI and 212 degrees F with a 4.0 orifice and a 1/4 inch quick-connect plug, from a maker that builds gas pressure washers. It suits owners of 3.5 to 4 GPM gas machines, hot or cold, who clean concrete, brick, stone and prep surfaces for paint. The caveat is the orifice: a 4.0 is too large for small electric washers, where it will not reach full pressure or spin properly.
Strengths
- 4500 PSI rating gives headroom over 4000 PSI gas washers
- Hot water capable to 212 degrees F, rare at this price
- Standard 1/4 inch quick connect fits most wands and lances
- Oscillating jet cleans concrete far faster than a fan tip
- From a pressure washer maker with parts and accessory support
Weaknesses
- 4.0 orifice is wrong for most electric washers
- Housing and insert materials are not named in the listing
- A rotary jet will damage soft wood and vehicles at close range

Who this nozzle is for
A turbo nozzle spins a 0 degree pencil jet in a tight cone, so you get the cutting power of the red tip across the footprint of a fan tip. It is the tool for stripping black algae from concrete, lifting years of grime off a sidewalk and prepping a deck or siding for paint. The Simpson 80144 is a 4500 PSI rated turbo nozzle with a 4.0 orifice and a 212 degree F hot water rating, which places it with gas pressure washers in the 3 to 4 GPM range rather than with small electrics.
This review is based on the maker’s published specifications and on recurring owner feedback. We have not run this product ourselves.
What you get
One turbo nozzle with a standard 1/4 inch quick-connect plug that fits most wands and lances. Simpson states a maximum of 4500 PSI, a maximum temperature of 212 degrees F and a 4.0 orifice, and claims cleaning up to 50 percent faster than a standard tip. The housing material and the internal nozzle material are not named in the listing; the maker’s line is that the nozzle is made for reliability and durability, which is the brand’s reputation but not a spec. No warranty term is listed.
Cleaning power
The 50 percent claim is the maker’s figure for the best case, usually flat concrete with surface grime. What matters is how it compares to the alternatives: against a 15 degree tip it cuts noticeably deeper per pass on hard surfaces, and against a 0 degree tip it covers far more ground without carving lines. Owners of rotary nozzles in this class report the biggest gains on driveways, pool decks and brick, and the biggest regrets on soft wood, where a spinning pencil jet at 3000 PSI or more will fur or gouge cedar and pine. Keep it to concrete, stone, brick and hard composite, or hold it well back on wood. Hot water capability to 212 degrees F is unusual at this price and makes it useful behind a hot water washer for grease.
Fit and compatibility
The plug is universal, but the orifice is not. A nozzle’s orifice number is sized to the washer’s flow and pressure; standard nozzle charts put a 4.0 orifice at about 4 GPM at 4000 PSI, and roughly 3.5 GPM at 3000 PSI. On a typical 2.5 GPM electric or small gas washer, a 4.0 orifice is too large: the pump cannot build full pressure through it, and the turbo spins weakly. On a 3.5 to 4 GPM gas machine it is right. Simpson sells turbo nozzles in other orifice sizes, so match the number to the tips that came with your washer rather than buying by pressure rating alone.
Build quality
Simpson is a pressure washer maker first, and its accessories are sized for its own gas machines. The 4500 PSI rating gives headroom over a 4000 PSI unit, and the hot water rating implies seals chosen for more than a cold garden-hose supply. The parts that wear in any turbo nozzle are the hardened seat and the spinning insert; a recurring complaint across the whole category is a nozzle that stops spinning after grit gets in, which is a flushing issue rather than a defect.
Living with it
Point the nozzle at the ground and pull the trigger before lowering it onto the work; a turbo nozzle needs flow to start spinning. If it stops spinning, back-flush it with a garden hose and tap it on your palm; do not poke a wire into the seat. Store it dry and upright. Use an inline filter at the pump inlet if you draw from a tank or a rusty well, since grit is what kills turbo nozzles. Never use it on a car, glass or soft wood at close range.
Alternatives to Consider
The Generac turbo nozzle is a comparable brand-name rotary tip for gas machines. For an electric washer under 2 GPM, the Sun Joe turbo nozzle or the smaller-orifice turbo tips sold for 1800 to 2300 PSI units will spin properly where a 4.0 orifice will not. For daily commercial use, a Suttner or General Pump rotary nozzle costs more and lasts longer.
Verdict
Buy the Simpson 80144 if you run a 3.5 to 4 GPM gas pressure washer, hot or cold, and your work is concrete, brick, stone and paint prep. Skip it if your washer is a small electric, where the 4.0 orifice is the wrong size, or if most of your cleaning is wood decks and siding, where a fan tip is safer.

It will connect, but a 4.0 orifice is sized for roughly 3.5 to 4 GPM. On a 1.2 to 2 GPM electric the pump cannot build full pressure through it and the jet spins weakly. Buy a turbo nozzle with a smaller orifice for an electric.
Yes. Simpson rates it to 212 degrees F and lists it as hot and cold water compatible, which is unusual for a consumer-priced turbo nozzle.
Usually grit in the seat. Point it down and pull the trigger to spin it up, back-flush it with a garden hose, and fit an inlet filter if you draw from a tank or well. Do not poke a wire into the seat.
Not at close range. A spinning pencil jet at 3000 PSI or more will fur or gouge cedar and pine. Use a 25 or 40 degree fan tip on wood and save the turbo for concrete, brick and stone.
