Quick verdict
A brass adapter that converts the M22 14 mm threaded fitting found on most consumer pressure washer guns to a 3/8 inch quick connect, with a 360 degree swivel that lets the hose rotate freely so it stops twisting into loops and dragging the gun. The inside diameter is 14 mm, not the 15 mm used on some washers, and the maker says so plainly; match it or it leaks. It is a cheap fix for the most annoying thing about pressure washing.

The Hose That Fights Back
Pressure washing a drive means walking in circles, and every circle puts a twist in the hose. By the third pass the hose is a tangle of loops dragging the gun sideways. A swivel at the gun lets the hose rotate freely and the twists fall out. Tool Daily’s adapter adds that swivel while converting the M22 14 mm thread on most consumer guns to a 3/8 inch quick connect, in brass with a stainless swivel.
This review is based on the listing specifications and on how swivel adapters perform on pressure washers generally. We have not used this adapter ourselves.
Fit
The maker is unusually direct: the inside diameter is 14 mm, not 15. Most consumer washers from Ryobi, Simpson, Generac, Sun Joe and others use M22 14 mm; some Karcher and a few European units use 15 mm, and the adapter leaks on those. Measure the bore of your fitting with a ruler before buying.
What It Changes
With the hose spinning freely at the gun, loops unwind themselves as you walk and the gun points where you aim it rather than where the hose pulls. Owners describe it as the accessory that made a long washing session pleasant instead of a wrestling match. The quick connect also means the hose clicks off the gun in a second for storage or to swap guns.
Build
Brass body, stainless swivel core, rated for consumer pressures with margin. Swivels are wear parts and may weep after years; a drop of silicone grease on the O-ring each season extends that.
Installation
Unscrew the hose from the gun, screw the adapter onto the gun inlet, click the hose’s quick connect plug into the adapter. If the hose has an M22 end, add a quick connect plug to it.
Who Should Buy It
- Anyone who pressure washes more than once a year.
- Owners of long hoses that tangle constantly.
- People converting a washer to quick connect fittings.
Common Owner Complaints
Leaks on 15 mm fittings. Measure first.
Care
A drop of silicone grease on the swivel O-ring at the start of each season keeps it turning freely and sealing. Rinse grit off the fitting before connecting, since sand in the swivel is what wears it. If it begins to weep after years, the O-ring is replaceable and the fitting is cheap enough to swap.
Converting the Rest
Once the gun end is quick connect, a plug on the hose end and a socket at the pump turn the whole washer into a click-together system. Hoses, guns and attachments then swap in seconds, which is how most people end up after their first swivel.
Alternatives to Consider
A 15 mm version of the same adapter for Karcher-type guns. A swivel at the pump end for those who prefer it there. A new gun with a built-in swivel.
Verdict
For a few dollars, a swivel at the gun removes the hose fight from pressure washing. Check 14 versus 15 mm, screw it on and the loops unwind themselves.

Measure the inside of your M22 fitting. Most consumer washers are 14 mm; some Karcher and a few others are 15 mm. This adapter is 14 mm and will not seal on 15.
Between the gun inlet and the hose. The hose then spins freely on the swivel as you move around the job.
Every time you turn, the hose rotates at the gun and stores a twist. Without a swivel the twists become loops that trip you and pull the gun. A swivel lets them unwind.
No. The bore matches the hose and the fitting is rated well above consumer pressures.
