Pressure washing gear for small crews: five picks that fit the job

The washer is already on the trailer. Now give it accessories that fit: a surface cleaner for the open slab, a manageable hose run, a reel that keeps pack-up tidy, and tips and an injector matched to the machine. That combination beats a pile of impressive pressure numbers that won’t connect.

Our five picks cover those jobs for a small crew. Start with your washer’s PSI and GPM, then work along the line to the nozzle. Pressure rating, flow range, temperature and connection type all earn a place on the shopping list.

Quick picks: build around the work

• Cold-water flatwork: SIMPSON 80625 surface cleaner — a 16.5-inch head for a 2,000–4,000 PSI, 2.5–4 GPM washer.
• Rewind and storage: General Pump D30002 reel — hand-crank storage for up to 100 feet of 3/8-inch hose, with a 4,000 PSI swivel rating.
• A 50-foot pressure-hose run: SIMPSON 41028 Monster hose — 3/8-inch hose with quick-connect ends for cold-water work.
• A matched set of spray patterns: SIMPSON 80146 nozzles — five tips with a 4.0 orifice specification and 1/4-inch quick-connect plugs.
• Downstream chemical application: General Pump 100775 injector — the fixed injector for a 3–5 GPM setup.

The fit sheet

Accessory	Pressure and flow	Connections / working limit
SIMPSON 80625 surface cleaner	2,000–4,000 PSI; 2.5–4 GPM	1/4-inch QC inlet; cold water, maximum 140°F
General Pump D30002 reel	Swivel: 4,000 PSI	3/8-inch NPT female ports; capacity: 100 feet of 3/8-inch hose; maximum 225°F
SIMPSON 41028 hose	Maximum 4,500 PSI	3/8-inch × 50 feet; male QC plug / female QC socket; maximum 140°F
SIMPSON 80146 nozzle set	Maximum 4,500 PSI; 4.0 orifice	1/4-inch QC plugs; maximum 212°F
General Pump 100775 injector	3–5 GPM; maximum 4,500 PSI	3/8-inch NPT male ports; 1/4-inch chemical hose barb; maximum 190°F

Buy these as individual fits for your rig. Account for the pressure-rated reel leader and adapters when connecting the hose; a quick-connect plug and an NPT thread are different ends. The nozzle orifice must also suit your washer’s flow and pressure.

Put the flatwork tool on a washer that can feed it

The SIMPSON 80625 is our pick for driveway and patio flatwork within its operating range. Its 16.5-inch head puts two rotating jets under a shroud, and the 1/4-inch quick-connect inlet attaches at the spray-wand end. The manual lists two extension wands in the package.

The useful numbers are 2,000–4,000 PSI and 2.5–4 GPM. Those are the minimum and maximum ratings in the 80625 owner’s manual, which also limits the cleaner to cold water up to 140°F. Match both pressure and flow before choosing the head.

Pick it for open, hard, level flatwork; keep the wand available for the edges and separate detail work. The 80625 maker page covers the connection and twin-jet layout. A wider head only earns its trailer space when the washer feeding it is a match.

Make the hose run easy to deploy and rewind

General Pump D30002: storage with a clear pressure limit

The D30002 is the reel pick for a small rig that needs hand-crank rewind and a locking pin. General Pump rates its capacity at 100 feet of 3/8-inch hose. Steel construction, a powder-coated finish and a brass swivel make up the basic package.

Keep the two ratings separate: hose capacity is a storage dimension; 4,000 PSI is the swivel’s pressure limit. Both inlet and outlet are 3/8-inch female NPT, with a maximum temperature of 225°F. General Pump puts all of that in its D30002 specification sheet.

Choose the reel around where it mounts and how the hose leaves the trailer. Leave enough room to turn the crank, operate the locking pin and get to the connections without unloading half the rig.

SIMPSON 41028: a defined cold-water hose run

The 41028 Monster hose gives you 50 feet of 3/8-inch hose, rated to 4,500 PSI and 140°F. Its steel-over-polyester braid, polyurethane outer jacket and four-inch bend protectors are useful features for a hose that gets deployed and coiled throughout the day.

The ends are a 3/8-inch male quick-connect plug and female quick-connect socket. Plan the reel’s threaded adapters and leader around those ends. The 41028 maker specifications identify the exact hose, rather than an M22-ended replacement that happens to look similar.

A higher-rated hose doesn’t raise the rating of the reel or cleaner. Build the connected setup to its lowest component pressure and temperature limits, as General Pump specifies in the injector guide below.

Keep the spray tips and chemical setup straight

SIMPSON 80146: colour tells you the angle

Choose the 80146 five-tip set when its 4.0 orifice suits your machine. The tips use 1/4-inch quick-connect plugs and carry a maximum 4,500 PSI rating. Keep the set together so the crew can find the intended pattern instead of grabbing whatever is rolling around the tray.

Colour	Pattern	Job in the set
Red	0°	Concentrated pinpoint spray
Yellow	15°	Narrow cleaning / stripping pattern
Green	25°	General cleaning pattern
White	40°	Wider pattern for softer surfaces
Black	Low-pressure soap	Apply cleaning solution

These are the 80146 maker’s colour codes, angles and specifications. Colour identifies the spray pattern; the orifice identifies another part of the fit. A green tip from a different set can have a different orifice. Select the orifice for the washer rather than treating every same-colour tip as interchangeable.

General Pump 100775: downstream draw for 3–5 GPM

The 100775 is the fixed downstream injector pick for a 3–5 GPM washer. It has a 2.1mm orifice, 3/8-inch male NPT inlet and outlet, and a 1/4-inch chemical hose barb. The maker rates it to 4,500 PSI and 190°F on its 100775 product page. A 2.5 GPM washer needs a different injector size, even though it can meet the surface cleaner’s minimum flow.

Install with the flow arrow downstream and use the low-pressure application setting to draw solution. General Pump’s Hi-Draw guide explains that nozzle setup and discharge-hose length affect draw; it also directs users to GP for corrosive-liquid applications. Match the chemical to that material guidance and the product label. Keep dilution tied to your actual setup instead of copying a fixed ratio from somebody else’s rig.

Wear eye protection, keep the jet off skin, and get prompt medical attention for pressure-injection wounds.

Pack the kit; keep the job record useful

A small crew needs a repeatable loadout more than another loose accessory. Give the tips one holder, keep compatible seals and fittings together, and make the reel part of the pack-up routine. For late-day loading, our rechargeable work-light guide covers area and hands-free options.

Before leaving, save the agreed scope and useful before/after photos with the job. Keep notes on the surface, access and the actual product used so the next visit starts with a record instead of a memory. Our pressure-washing software guide starts with Jobber for handling that business workflow.

The small-crew loadout checklist

• Match cleaner PSI and GPM to the washer.
• Size the injector for the washer’s flow.
• Lay out the leader, NPT adapters and quick-connect ends before mounting the reel.
• Keep the nozzle set’s orifice size with its storage holder.
• Pack the hose so the fittings and bend protectors are easy to inspect.
• Save the scope, finish photos and product notes on the job.

If the quote visit takes you through the customer’s house, keep boot covers and floor runners with the survey kit. A tidy arrival and a tidy pack-up bookend the work.

For a route that includes glass, keep a separate window-cleaning kit with the water-fed pole, DI tank and hand-finishing tools.
