An M22 14mm-to-15mm pressure washer adapter connects equipment with different M22 insert sizes, but the thread direction and fitting style must match. The M MINGLE 15mm-female-to-14mm-male adapter is a straightforward choice for that conversion; its two-pack is better for keeping a spare. The WOJET model is designed to connect an M22-14mm hose to an M22-15mm washer outlet, while the M MINGLE male-to-male pair serves a different fitting arrangement. Check the equipment manual or measure the fitting before ordering.
| Adapter | Connection style | Best for |
|---|---|---|
| M MINGLE single | 15mm female to 14mm male | One direct conversion |
| M MINGLE two-pack | 15mm female to 14mm male | A spare or second connection |
| Brass hose adapter | 15mm female to 14mm male | Buyers seeking a brass fitting |
| M MINGLE male-to-male | 14mm male and 15mm male | Matching two female connections |
| WOJET swivel adapter | 15mm female swivel to 14mm male | Connecting a 14mm hose to a 15mm outlet |
M MINGLE M22 15mm Female To 14mm Male Adapter
This adapter changes an M22 15mm female connection to an M22 14mm male fitting. The listing names 14mm-side compatibility with brands including Generac, Simpson, Briggs & Stratton, Craftsman, Karcher, and Ryobi. It lists Sun Joe, Campbell, MI-T-M, AR Blue, Stanley, Cleanforce, Simoniz, and Excell among 15mm-side examples.
Best for: Buyers who need one clearly specified 15mm-female-to-14mm-male adapter for a compatible hose, gun, or pump connection. It was selected for its explicit direction and brand guidance. Caution: The listing says it does not connect a Sun Joe pressure washer wand to a pressure washer gun.
M MINGLE Two-Pack M22 Adapter
The two-pack uses the same stated conversion: M22 15mm female to M22 14mm male. The listing identifies compatible brand examples for both fitting sizes and notes that the adapter is for M22 threads, not other sizes such as 1/4-inch or 3/8-inch connections.
Best for: Buyers who need two adapters or want a spare in the workshop. Choose this if the connection direction matches your equipment. Caution: It does not reverse the conversion; it will not serve a 14mm-female-to-15mm-male requirement. The listing also excludes Sun Joe pressure washer wands.
Brass M22 Hose Adapter
This listing describes a metric M22 15mm female-to-14mm male connector for pressure washer hose, gun, or pump connections. Its features specify a brass construction and corrosion resistance. The listed working pressure is up to 4,500 PSI.
Best for: Buyers who want the stated brass construction and need the specified female-to-male conversion. It was selected as another option with the same basic connection direction. Caution: Confirm both fitting sizes and the equipment’s pressure requirements; the listing’s feature details state up to 4,500 PSI.
M MINGLE M22 Male-To-Male Adapter Pair
This two-pack has M22 15mm male and M22 14mm male ends, with arrow markings to identify the sizes. Unlike the female-to-male adapters above, this design is for joining compatible female-side fittings. The listing describes it as a pressure washer coupler for connections such as a gun and hose.
Best for: Buyers whose two connection points are both female and need different M22 insert sizes. The marked ends make it easier to distinguish the 14mm and 15mm sides. Caution: Avoid this design if your equipment requires a female end on the adapter.
WOJET M22 Swivel Pressure Washer Adapter
WOJET describes this adapter as an M22 15mm female swivel connection to an M22 14mm male fitting. It is intended to connect an M22-14mm pressure hose to a washer with an M22-15mm outlet. Features include nitrile O-rings and American-standard M22 threads. The listing names several 15mm-outlet examples and excludes Sun Joe SPX200 and SPX6000 QC versions.
Best for: Buyers who specifically need a 14mm hose connected to a 15mm electric washer outlet. The swivel design and stated sealing components distinguish it from the basic adapters. Caution: The listing says it is not required for M22-14mm units, including Ryobi and Greenworks examples.
Buying Guide: How To Choose An M22 Adapter
Which fitting direction do you need?
Match the adapter’s female and male ends to the equipment, not just the 14mm and 15mm measurements. These products include 15mm-female-to-14mm-male designs, a 14mm-male-to-15mm-male pair, and a swivel model intended for a 14mm hose and 15mm outlet. A reverse connection may require a different adapter.
How can you check 14mm versus 15mm?
Measure the fitting as directed by the product listing, or check the pressure washer and accessory manuals. The listings describe measuring the inside plug at a female end or the inside diameter of a male end. Do not assume all M22 fittings have the same insert size.
Does every M22 adapter fit every pressure washer?
No. Confirm the thread type, insert size, and end gender on both connected parts. M22 adapters do not fit non-M22 connections simply because the equipment is a pressure washer. Brand names can help narrow the search, but the actual fitting should still be verified.
What pressure rating should you check?
Compare the adapter’s stated working pressure with the pressure washer’s requirements. The brass adapter listing specifies up to 4,500 PSI. The first M MINGLE listing also identifies a 4,500 PSI rating in its product name. Do not exceed the rating stated for the adapter.
Frequently Asked Questions
What does an M22 14mm to M22 15mm adapter do?
It connects compatible pressure washer parts with M22 fittings that use different 14mm and 15mm insert sizes. The exact adapter must match the fitting direction and gender.
Can a 15mm-female-to-14mm-male adapter be reversed?
No. That adapter has a defined end arrangement. For the opposite conversion, select a product that explicitly lists the reverse direction.
Will these adapters fit a Sun Joe wand?
The M MINGLE listings specifically warn that their adapters do not connect Sun Joe pressure washer wands to pressure washer guns. Check the exact model and connection before buying.
Is an M22 adapter suitable for a 1/4-inch connection?
No. An M22 adapter is intended for compatible M22 fittings. The two-pack listing specifically excludes non-M22 connections such as 1/4-inch and 3/8-inch fittings.
