- Priced higher than non-swivel alternatives
What's inside
Buying a pressure washer accessory sounds simple until you realize how many connection standards exist. Your M22-14mm inlet will not accept a 3/8″ male plug without an adapter, and a foam cannon with the wrong coupler will drip soap all over your driveway instead of dispensing a thick, clinging layer. The real problem most owners face is not finding a good McKillans pressure washer component — it is finding the right one for the specific inlet and outlet configuration of their machine.
What separates a good accessory from a bad one in this category comes down to fitment precision, seal quality under sustained pressure, and connector durability across seasonal use. Owners consistently flag leaking swivel joints and kink-prone hose sections as dealbreakers. The McKillans line addresses these failure points with steel-braided construction, pre-installed stainless plugs, and clearly marked connector types. Below we compare the full accessory range by spec and price to help you match parts to your machine without guessing.

How We Picked
We evaluated each McKillans pressure washer accessory on four criteria: connection compatibility with common machine inlets (M22-14mm or 3/8″ male), construction material grade (stainless steel versus brass versus reinforced polymer), kink and leak resistance reported by owners over months of use, and value relative to competing accessories with similar specs. Price was considered only after fitment and durability were established, since an incompatible connector is worthless at any price.
The 8 Best Mckillans Pressure Washer in 2026
1. McKillans Short Pressure Washer Gun with Swivel
This gun suits owners who attach a foam cannon or extension wand frequently and need a swivel joint that prevents hose torque from pulling on the machine inlet. The 3/8″ male plug connects to M22-compatible adapters, while the 1/4″ quick connector accepts standard quick-disconnect accessories without tools.
- Swivel reduces strain on hose and machine coupling during overhead spraying
- Dual-connector design offers flexibility across gun-to-wand and gun-to-cannon setups
- Priced higher than non-swivel alternatives
Skip this if your machine already has a 1/4″ quick connect outlet and you never use a foam cannon — the swivel adds cost without solving a problem you have.
2. McKillans Foam Cannon Wide Mouth
The wide-mouth bottle is the standout feature here, making soap mixing easier and reducing splash during fill compared to narrow-tube alternatives. With a 1/4″ quick connector coupler, it mates directly with compatible guns and the extension wand above. Adjustable foam thickness lets you dial in a dense clinging layer for heavy dirt or a lighter rinse pass.
- Wide mouth reduces mess during detergent mixing
- Adjustable nozzle controls foam density across wash stages
- Requires a compatible 1/4″ quick connect gun to function
Skip if your gun uses a threaded attachment rather than a 1/4″ quick connect, or if you prefer bucket-wash soap without foaming.
3. McKillans QC Pressure Washer Hose 50 ft
Pre-installed 3/8″ stainless steel quick connectors eliminate the common frustration of buying a separate adapter kit. The steel-braided jacket resists abrasion against concrete and gravel, and the kink-resistant construction maintains flow through bends that would collapse a plain polymer hose. Fifty feet gives enough reach to circle a full-size vehicle without resetting.
- Stainless QC plugs installed at factory, no extra parts needed
- Steel braid handles repeated dragging on rough surfaces
- Highest price in the hose category
Skip if your machine outlet is M22-14mm and you do not plan to use a 3/8″ adapter — the pre-installed connectors become a limitation rather than a convenience.
4. McKillans M22-14mm Quick Connect Kit Stainless Steel
This kit converts an M22-14mm outlet to 3/8″ male/female quick disconnect, enabling the pre-installed QC hose above or any 3/8″ accessory to mate with a common residential pressure washer. Stainless steel construction resists corrosion from detergent exposure and seasonal storage in damp garages better than brass alternatives.
- Stainless steel tolerates harsh detergent chemistry without degrading threads
- Male and female pieces included, covering both inlet and outlet conversions
- Not universally compatible — some machines use M22-15mm or bayonet
Skip if your machine uses a bayonet fitting or a brand-proprietary coupling that this kit does not address.
5. McKillans M22-14mm Quick Connect Kit Brass
Functionally identical in connector type to the stainless version, this brass kit saves $20 and still provides a solid seal on M22-14mm inlets. Owners report comparable leak performance for casual seasonal use. Brass is softer than stainless, meaning threads can deform under over-torquing or repeated cross-threading.
- Significantly lower price than stainless equivalent
- Same M22-to-3/8″ conversion geometry for broad accessory compatibility
- Brass threads are more vulnerable to cross-threading damage
Skip if you store accessories outdoors or use strong acidic cleaners that accelerate brass corrosion.
6. McKillans Car Pressure Washer Extension Wand
The extension wand reaches wheel wells, undercarriage gaps, and roof sections without requiring you to stretch or climb. At 1/4″ quick connect, it pairs with the short gun and foam cannon for a modular car-wash stack. Replacement wands typically cost less than a full gun assembly, making this a practical upgrade when your existing wand cracks or loses a tip fitting.
- Adds length without changing your gun or hose setup
- Replaces stock wands that fracture at the tip joint
- Extends total spray length, which slightly increases water column loss
Skip if your machine is already a long-reach commercial unit with an integrated telescoping boom.
7. McKillans Pressure Washer Hose 50 ft M22-14mm
This hose connects directly to machines with an M22-14mm inlet without an adapter, removing a failure point for owners who want a single-coupling setup. The steel-braided outer layer and 1/4″ inner diameter mirror the construction of the QC version, trading factory-installed quick disconnects for a simpler threaded plug that costs ten dollars less.
- Direct M22 connection eliminates adapter leak risk
- Kink-resistant steel braid rated for high-pressure cycles
- Threaded plug requires tools to install or remove
Skip if you want tool-free accessory swapping during a wash session, in which case the QC hose is the better fit.
8. McKillans Short Pressure Washer Gun M22 Inlet
At the same price as the brass kit and cheaper than the swivel gun, this model serves owners with M22 machines who want the quick-connector workflow. The 1/4″ coupler accepts foam cannons and extension wands, while the M22 inlet screws directly onto the machine — no adapter needed. The trade-off is no swivel, so hose torque transfers to your wrist during extended overhead use.
- M22 inlet means zero adapters for common residential machines
- 1/4″ QC outlet opens the full accessory ecosystem
- No swivel, causing wrist fatigue on tall or long sessions
Skip if you spray overhead for extended periods and want to reduce torque on your joints — the swivel gun solves that for twenty dollars more.
Buying Guide
Match Your Machine Inlet First
The most common compatibility failure is buying an accessory with a connector your machine does not have. Before selecting a McKillans pressure washer component, check whether your machine inlet is M22-14mm threaded, 3/8″ male, or a proprietary bayonet. The M22 hose and M22 gun connect directly without adapters, while the 3/8″ QC hose and 3/8″ gun require the stainless or brass conversion kit on an M22 machine. Getting this wrong is the single biggest source of returns.
Stainless Versus Brass for Outdoor Storage
If you leave accessories coiled in a shed or garage that experiences humidity swings, stainless steel connectors resist surface oxidation better than brass. Brass performs fine for owners who drain and store components indoors between washes. The twenty-dollar premium for stainless is worthwhile only when environmental exposure is realistic in your storage situation.
Hose Braid and Inner Diameter
A steel-braided jacket protects against concrete abrasion and pinch points that would split a plain polymer hose. The 1/4″ inner diameter in both McKillans hose options supports adequate flow for typical residential pressure washers. If you own a commercial unit above four gallons per minute, confirm that 1/4″ does not restrict flow on your machine before buying.
Our Verdict
Our top pick is the McKillans QC Pressure Washer Hose at $89.97, because it eliminates the most frustrating part of accessory ownership — hunting for compatible connectors — by shipping with stainless quick disconnects already crimped in place. For owners on a tighter budget, the Short Gun with M22 Inlet at $39.98 delivers the core quick-connector workflow without any adapter purchase. However, if you store gear outdoors or wash with acidic wheel cleaners, the stainless Quick Connect Kit at $59.88 becomes the priority buy, since a corroded adapter will compromise your entire setup regardless of which hose or gun you choose.
FAQ
Are McKillans accessories compatible with all pressure washer brands?
No single accessory fits every brand, which is why McKillans offers both M22-threaded and 3/8″ quick-connect variants. M22-14mm is the most common residential inlet standard, but some manufacturers use M22-15mm or proprietary bayonet couplings that require a machine-specific adapter beyond what McKillans provides.
What is the difference between the two 50-foot hoses?
The $89.97 version has factory-installed 3/8″ stainless quick connectors, enabling tool-free attachment to any 3/8″ QC gun. The $79.98 version uses a threaded M22-14mm plug, which screws directly onto compatible machines but requires a wrench to install. Both share the same steel-braided outer layer and 1/4″ inner diameter.
Can I use the foam cannon without a compatible gun?
No. The wide-mouth foam cannon connects via a 1/4″ quick connector, which requires a gun or wand with a matching 1/4″ female coupler. Pairing it with the short swivel gun or the M22 gun gives you a complete foam-cannon workflow without additional adapters.
Do brass connectors corrode faster than stainless ones?
Brass is softer and more susceptible to dezincification in prolonged moisture exposure, while stainless resists surface oxidation. For indoor-stored accessories used seasonally, brass performs identically to stainless. The material difference matters primarily in damp storage or when aggressive chemical detergents are part of your routine.
