  • 19" wand with 1/4" quick-disconnect end for simplified spray tip exchange
  • Five color-coded spray tips with 0, 15, 25, 40, and 65-degree spray patterns for a variety of uses

If you are looking for the best replacement washer gun kit on the market, then look no further. The Apache 99023802 is the best residential trigger gun.

You get a spray gun, a pressure wand, and a set of multi color-coded quick-connect spray tips and two adapters to ensure it will be compatible with as many pressure washers as possible.

The quick-connect tips are the full set of 5, covering 0-degrees, 15-degrees, 25-degrees, 40-degrees, and the soap nozzle so there isn’t a job you can complete.

  • Gun and variable wand kit
  • Variable nozzle adjust from 0 degrees to 40 degrees at low (soaping) and high pressure settings
  • Use as a replacement for original gun on pressure washers rated to 2600 psi

Here’s another model from Apache, while it can’t handle as much pressure as the previous model on this list, this is still a fantastic option.

You get a spray gun and a variable wand, the variable wand which adjusts from 0-degrees to 40-degrees and also a low-pressure soaping setting.

You can use this on both gas and electric pressure units, though very few gas units produce pressure low enough.

This wand can handle pressures up to a maximum PSI of 2600, which is perfect for medium-duty pressure washers.


  • Easy to control and maintain.
  • Variable wand giving access to all spraying angles
  • Durable trigger.


  • Unable to do heavy washing jobs.

If you are looking to just upgrade the trigger gun, then look no further. This is the upgrade I suggest for residential uses.

The manufacturer, Suttner, calls this trigger gun a “relax-action” trigger.

The idea behind this trigger gun is to allow easier pressure washing for long periods, I don’t know about you but my hand aches after a long pressure washing session, using this trigger gun changed that.

This spray gun helps reduce fatigue, and this only includes the trigger part, so you’ll need to purchase a stainless steel lance/wand and nozzle tips separately.

This isn’t a disadvantage, you can attach spray foam cannons better, which improves your ability to foam your car. Plus, you can mix and match to your heart’s content to get the perfect setup.

Thanks to its ability to handle up to 5000 PSI, this will work well with gas and electric pressure washers.


  • Can handle up to 5000 PSI
  • Works with both gas and electric pressure washers
  • Reduces fatigue for long periods of use


  • No nozzle tips or spray lance

Ok.. I must admit that this one is a bit of fun, this is the choice amongst professionals, yes you can use it for residential purposes, but it’s aimed entirely at professionals.

The Suttner ST-3600 is one of the most expensive models on the market because it allows enormous amounts of water flor and has a very high chemical resistance.

But how much flow? 21 GPM at 8700 PSI.

Professional mobile power washers are enormous fans of chemical resistance. It allows them to be worry-free use of the downstream chemical injection, used to clean surfaces as fast as possible.


  • Huge pressure capacity
  • Huge flow rate
  • Chemical resistance


  • Not cheap
  • Aimed at professionals

Anatomy of Pressure Washer Spray Guns

While there are many pressure guns on the market, they are all engineered with very minor differences.

That said, they are all operated around a trigger activated ball valve.

A spray gun is made up of:

  • The out plastic case
  • The trigger parts
  • The control pin. When you pull the trigger, it pushes the ball into the valve, allowing the water to flow through the nozzle
  • The ball valve that blocks the water flow until you pull the trigger

You’ll find that the pressure washer industry has many terms to describe the same parts when it comes to spray guns, so it can be overly complicated.

Industry Names for Spray Gun Kits

It’s most accurate to call the part which holds the trigger, the spray gun, and the steel part with the nozzle tip the lance or wand.

Typically the spray gun, sometimes called a trigger gun, has a 1-foot plastic casing; this is where the steel tube is usually housed.

However, you may have a gun that is very similar but doesn’t have the 1-foot casing; this is often referred to as a trigger gun.

Now you have an understanding of the parts and names for guns, check out this video below, show the how spray guns come apart in this disassembling video.

How the Trigger Gun Works

The main parts of a spray trigger gun are the valve and the trigger interaction.

When the trigger is locked, I.e., you haven’t squeezed it, the ball inside the valve is sitting in place, being held there by a spring blocking the water from going through.

When you pull the trigger, the trigger rotates around on an axis and pushes down on the control pin. What this does, it effectively pushes the ball against the spring holding it in place, this moves the ball out of the way so that the water can flow through the valve to the spray nozzle.

When you release the trigger, the spring pushes the ball back onto its seat, blocking the water flow.

That’s not all that happens, in addition to the valve and trigger interaction, there’s also the interaction between the trigger gun ball and the unloader valve on your pressure washer pump.

When the pressure washer is turned on, but you haven’t pulled the trigger, it’s the job of the unloader valve is to divert the water from the pump back to the pump inlet so that the pressure doesn’t build too high. It knows to do this by sensing an increase in the pressure or a change in the water flow.

When you pull the trigger to pressure washer something, the unloader valve senses the pressure or flow changes (this depends on the type of the unloader valve) and stops diverting water flow through the pump.

Two Main Styles of Replacement Guns

Best Pressure Washer Gun

There are two types of replacement spray gun which you can purchase.

  1. Full kits – These include the spray gun, the spray lance, the nozzle tips, connections, and sometimes even a high-pressure hose.
  2. Just the spray or trigger gun, this doesn’t include the extras such as the lance, nozzles or connections, you just get the gun.

The most common part to break on your spray/trigger gun is the trigger gun assembly part itself, so you may need to replace just that alone.

It may be easier to just buy the full kit, to remove any doubt about connections and fittings.

Are Replacement Guns Universal, or Do I Need the Same Brand as My Pressure Washer?

With the availability of threaded and quick-connect connection fittings, you can make any spray gun 100% universal. You don’t need to purchase a replacement or upgrade spray gun; that’s the same brand as your pressure washer.

Just note, that if it breaks within the warranty people, it’s an easy part for your manufacturer to replace.

What’s the Difference: Industrial Spray Gun vs. Residential Medium-duty?

Industrial spray guns are designed to work perfectly with the specifications of industrial power machines. Hot water capable power washers, high flow rate, and high pressures that the best gas pressure washers produce work perfectly well with industrial trigger guns, but can break the residential spray gun models, as these aren’t designed for the high specs.

Also, the higher specs of the industrial guns will cost more, as they are made with higher quality valves and material components

Typical Industrial Spray Gun Specs

You’ll see one of the most popular trigger guns on this list, it’s the Suttner St-2700 which is made with stainless steel components.

Here are its specs:

  • Water Flow: 12 GPM
  • Pressure: 5000 PSI
  • Temperature: 300 F (149 C)
  • Inlet Size: 3/8″ FPT
  • Outlet Size: 1/4″ FPT
  • Weight: 1.24 lbs (562 g)

Typical Residential Spray Gun Specs

These are the specs from another popular spray gun on my list, though this one is squarely sat in the residential market. It’s the Apache 99023802.

Here are its specs:

  • Flow: 7 GPM
  • Pressure: 4000 PSI
  • Temperature: 140 F (60 C)

You might be surprised to know that you can use an industrial trigger gun with a residential electric pressure washer. I’ve upgraded my residential pressure washer with a trigger gun from a commercial-duty pressure washer if you are wondering, I own the Suttner St-2700 202700600.
