Pressure washer fittings are the heart of your pressure washer, without them your pressure washer won’t function and perform properly. If you’re a do-it-yourself person, you need to be aware of pressure washer fittings. The fittings are essential to the success of any pressure washer project, and they come in a variety of styles. You also need to know if your pressure washer can accommodate these fittings before buying them.
However, one of the most common things that most people fail to consider about pressure washing supplies is the compatibility factor from one model to another. Read on to learn more about their compatibility. So, are pressure washer fittings universal?
Pressure washer fittings are not universal. They are designed to fit specific hose sizes, and this is why you have to have the correct size for your hose in order for it to work correctly. If you use a smaller fitting on a larger hose, then water pressure will be lost. If you use a larger fitting on a small hose, then water will leak out of the connection and leave you with a mess on your hands.
However, what would be the number one benefit of universal fittings is convenience. You wouldn’t have to worry about any leaks or problems when using these attachments because they would have been designed specifically for use with other types of hoses. This would be perfect for people who do not want to spend hours trying to figure out how each piece works before they can start using their unit.
Types of Pressure Washer Fittings
There are three main types of fittings, male quick connects, female quick connects and standard garden hose threads (GHT). Male quick connects have a male end that screws onto the female end of a hose or spray gun. The male end usually has a rubber gasket to prevent leaks.
Female quick connects also have a rubber gasket at the connection point but instead of having threads like a garden hose fitting does, it has grooves which flex when pressure is applied to them so that they can seal against each other. Standard garden hose threads are used on most pressure washers because they allow you to use any standard garden hose attachment.
Standard Pressure Washer Fitting Sizes
Standard pressure washer fitting sizes are a great way to get your pressure washer up and running. These standard fittings are typically used in residential homes as well as commercial applications. The following is a list of common fittings and their corresponding sizes.
1/4″ Male Pipe Thread to 1/4″ Female Pipe Thread: This fitting is used for connecting 1/4″ male pipe thread to 1/4″ female pipe thread. It is also sometimes called a “nipple.”
1/4″ Male Pipe Thread to 3/8″ Female Pipe Thread: This fitting is used for connecting 1/4″ male pipe thread to 3/8″ female pipe thread. It is also sometimes called a “nipple.”
1/4″ Female Pipe Thread – Used for connecting hoses and nozzles to pressure washers. Used on most commercial-grade pressure washers.
3/8″ Female Pipe Thread – Similar to 1/4″ but with a larger diameter opening. Used for connecting hoses and nozzles to pressure washers. Used on some commercial-grade pressure washers and some residential-grade models.
1/2″ Female Pipe Thread – Similar to 3/8″, but with even larger diameter opening. Used for connecting hoses and nozzles to pressure washers. Used on all residential-grade models as well as some commercial-grade models
So, no, pressure washer fittings are not universal despite the overwhelming number of power washers that are similar in appearance. Do not assume you know what commodity you will get before you buy. Always check the manufacturer data. That way you can be sure about what fitting you’re purchasing and avoid getting incompatible fittings for your power washers.
On one hand, the standardized nature of these fittings is indeed a convenience for consumers. In past years, the variety of pressure washer connections was once one of the most difficult barriers to entry for anyone looking to purchase a pressure washer. It would have been tough to use your previous garden hose with extension connectors on the new machine. Now it’s not an issue.
