Quick Connects, the parts that enable the user to quickly change from different hoses to different accessories, is a broad term used to cover 2 main types of couplers.  The twist coupler that works like a reverse garden hose connection and the socket and plug much like an air hose fitting.

The Quick Connect consists of 2 parts.  The socket, typically with 8 ball bearings and a spring loaded collar.  The part that goes into the socket is the plug.  The two main sizes most commonly used with pressure washers are ¼ inch, used mainly on the discharge outlet of the trigger gun as well as the end of the spray wand to hold the color coded spray tips.  The 3/8 inch size is most commonly used in the connection of the hose to the machine and between the hose and the trigger gun. 

The other end will have either a male, external thread or a female,  internal thread.  So, when ordering couplers it is good to know the correct terminology to ensure you get what you want.   Example:  3/8 inch female socket or ¼ inch male plug.  These can make life a lot easier to say the least.  The one thing to be aware of on the socket portion is the oring that seals the plug down inside.  Sometimes when flushing out the system or purging the air from the pressure washer, this oring can  become dislodged and get lost in the water stream. The will be evident by a loose fitting spray tip in the socket as well as low pressure.  All of our Water Cannon machines come with a couple extra orings of each size to cover the nozzle socket as well as the hose socket. 

The 22 millimeter Twist Connect has 2 parts as well.  The Twist seal connect that works like a garden hose swivel with a hollow stem with an oring in the middle and a screw plug which would be like a garden hose spigot.  The outside diameter of the threads on the screw plug measures 22 millimeters and the inside diameter typically measures 14 millimeters.  Like the quick connects mentioned earlier, these too will have 3/8 and ¼ inch male or female threads opposite the coupling.  The twist connect is not as fast to connect or disconnect but works well just the same.
