Pressure Washer Hose Buyer's Guide

High-pressure hoses are a lot like car tires.

After so much use (or misuse), they eventually wear down and need replacing.

We recommend a heavy-duty hose. The durable materials in these hoses will not kink and curl like lesser hoses.

There are four things you'll need to consider when choosing your replacement hose:

1. Length
This is a no-brainer. Get a long hose or a short hose. That’s easy.

2. Diameter
Diameter is a little trickier. Hoses come in three widths: 1/4”, 5/16”, 3/8”.

Pressure Washer HoseSmall (1/4") hoses are the most common. They are designed for consumer-grade electric and small gas power washers with pressure less than 2700 psi.

Mid-sized (5/16”) hoses are the least common. They are rated for prosumer-grade gas pressure washers that can withstand pressures between 2700-3400 psi.

Large (3/8”) hoses are designed for all professional - and some prosumer-grade gas pressure washers. These hoses can withstand serious water pressure up to 5000 psi. Plus, they’re thicker to allow greater water volume.

3. Material
High-pressure hoses are made from three types of materials: PVC Plastic, Rubber and Polyurethane.

Polyurethane Pressure Washer HosePVC Plastic hoses are the most common. These hard, plastic hoses do the job, but they’re not very flexible. If you get frustrated fighting your hose, you should consider upgrading to rubber or polyurethane.

Rubber hoses are heavier and more flexible than ordinary plastic hoses. They don’t kink and curl as often. However, rubber hoses tend to mar the surface with a black substance as you slide them across the concrete.

Polyurethane hoses are relatively new to the market. The steel-braided hose is covered with a clear, bendable plastic. Professionals love these hoses because they offer the flexibility of rubber without the marring.

4. Connections
Every hose has two connections: One connects to the pump. The other connects to the spray gun.

Power Washer HoseThere are only two ways you can connect a hose to the pump. You can either twist or snap them together.

There are four ways you can connect a hose to the gun. Take a good look at the inlet on your gun. Most have a threaded male connector sticking out. Some are female. Some are quick connect plugs.

If your gun has a male thread, congratulations. You simply need to buy an ordinary replacement hose with two M22 threaded (female) connectors. One end screws into the pump the other screws into the gun.

Pressure Washer HoseIf you have a Karcher electric gun, you simply need to buy the Karcher K3 replacement hose. It is exclusively designed to snap into Karcher electric trigger guns.

If you’re gun isn’t a Karcher, but still has a female thread, don’t worry. You can still buy an ordinary female/female replacement hose. You’ll just need to buy a hose/gun adapter too.

If you’re gun has a male quick-connect plug, you simply buy a professional-grade hose with a 3/8” female snap coupler.
