Simpson Pressure Washer Parts and Accessories

Axial Vs. Triplex Pumps

You should always decide what type of pump you want in your pressure washer. Axial cam pumps wear downs quickly because they are directly driven by the engine which means they spin at the same speed as of engine. However, Triplex plunger pumps are one of the most suitable pressure washer pumps. They are not directly driven and offer better performance.

OEM Replacement Pumps.

Technically you are required to replace axial cam pumps and repair triplex plunger pumps. You can get your hand on these pumps online or by it directly from Simpson’s parents’ company subsidiary brand “AAA”.

As a general rule axial cam pumps are replaced not repaired and triplex plunger pumps are repaired not replaced.

Nozzles and Spray Tips

Different nozzles or spray tips are necessary to tackle cleaning jobs of various surfaces. For example, you need a wide nozzle to clean a large camper or RV while a 0-degree spray tip is perfect for tough stains on concrete or metal surfaces. So Simpson power washer provides with 5 types of nozzle, i.e, 0º, 15°, 25°, 40°, and the soap nozzle with most of its models. You can easily interchange them to clean the area effortlessly.

Pump Saver

It is an important accessory that goes into the pump and helps you store the power washer in a cold climate or during winters. If you are planning to store for a long period of time then you should have a pump save which only cost around $10-$20 that you buy from any power equipment store.

Fuel Stabilizer

Cold climate has never been a friend for machinery which is why having a fuel stabilizer is essential to protect your Simpson pressure washer.

Brass Coupler

A brass coupler is a link between your high-pressure hose and pressure washer. It is a very important washer accessory that you should buy and avoid synthetic coupler as they tend to blast or leak. Make sure that the size of the brass coupler is perfect for both hose and washer.
