High-pressure hoses are a lot like car tires. After so much use (or misuse), they eventually wear down and need replacing.
Consider these four options as you try to clone your broken 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”.
Small (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.
PVC 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.
There are only two ways that 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 you’re gun has a male thread, congratulation. 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.
If 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.
