Why Choose This M22 to Garden Hose Adapter?

What "M22" and "GHT" Actually Mean

M22 is the metric fitting found on most pressure washer pumps—22mm diameter with fine threads. GHT (Garden Hose Thread) is the standard U.S. garden hose threading. These two standards don't connect directly, which is why this adapter exists.

How to Confirm You Need This Adapter

Check both ends. Your pressure washer inlet should be M22 male (threads outside). Your garden hose should be 3/4" GHT male (threads outside). If your hose has a female end instead, you'll need the male version of this adapter—see the link below.

When to Use This Adapter

Use it when you want to run your pressure washer from a garden hose—common for car washing, patio cleaning, and driveway rinsing where a full pressure washer hose isn't practical. Also handy for RV owners using campground water.

Brass vs Plastic at High Pressure

Pressure washers push water at up to 5000 PSI. Plastic adapters can crack or blow off under that load, especially after UV exposure. Solid brass holds its shape and threads under pressure—which is why every serious pressure washer setup uses brass fittings.

Installation Tips

Hand-tighten the M22 side first, then a quarter turn with a wrench if needed—don't overtighten, as M22 threads are fine and can strip. The GHT side uses the built-in O-ring, so no PTFE tape is needed. If it drips at the M22 connection, check that the O-ring is seated flat.
