Pneumatic Quick Coupler Types

The most common air hose fittings are 1/4″ NPT with an industrial quick connect threaded on. In certain warehouses or industrial areas, where a higher CFM (cubic feet per minute) and PSI are required, 3/8″ male NPT with a quick disconnect will be more common.

What are the different types of hydraulic couplers?

There are three common types of coupling interfaces used in hydraulics today: thread interface, mated angle, and O-ring.

Are quick connect fittings universal?

Universal standard 3/4" inch garden hose quick connect fittings fits all garden hoses, watering devices, sprinklers, etc. Easy to connect and release female coupler and male plugs for a quick exchange of attachments or to move to a different faucet.

How many types of air couplers are there?

There are two main types of air compressor couplers : Automotive and Industrial. The chart below shows how to identify which connector style you have. As you can see, Industrial style couplers have two striped going across the fitting, whereas the automotive style only has one.

Are all quick connects the same?

The below FAQ should help you understand how to select quick couplers for their common applications. Q: Are all quick couplers the same? A: No, there are two primary construction styles for hydraulic quick couplings. The check valve style system uses either balls or poppets to block flow from exiting the fitting.

What is a universal air coupler?

Universal hose couplings, also known as Chicago and air hose couplings, have an identical claw-style head that allows you to connect to another Chicago hose coupling, regardless of the pipe size or barbed hose ID.

How do I know Quick Connect size?

If you are running ½ inch hose you will most likely use a ½ inch body fitting with ½ inch male or female pipe thread. If a product number is stamped on an air coupler or fitting usually the first number is the body size and if there is a second number it will be the thread size.

What are quick connect fittings called?

Quick disconnect fittings (abbreviated as “QDCs” or “QDs”) are used to provide fast and easy connection and disconnection of fluid lines. These fittings are also known as quick connects or quick release couplings.

What is quick acting coupling?

Quick-acting couplings provide a fast, convenient way to repeatedly connect and disconnect fluid lines.

What is a quick release coupling?

Quick disconnect fittings are used to provide fast and easy connection and disconnection of fluid or air lines. These fittings are also known as quick connects or quick release couplings. They are used to replace fitting connections that would require tools to assemble and disassemble.

What is a JIC hydraulic fittings?

JIC (or Joint Industry Council) fittings, defined by SAE J514, are compression fittings machined with a 37 degree flare seating surface and parallel threads. They are commonly manufactured in nickel alloys, brass, carbon & stainless steel. JIC Fitting hydraulic connections are common in most fluid power systems.

What does ARO stand for in air fittings?

One thick stripe and one thin stripe on body of fitting. Semi-Automatic. Semi-Universal Interchange Profile (ARO, Automotive, Industrial) not applicable. Three thin stripes on body of fitting.

Can air Quick Connect be used for water?

(Sometimes you will see pneumatic quick disconnects referred to as air couplers.) Depending upon the material and configuration, quick disconnects can be used in the transference of air, hydraulic fluid, oil, water, chemicals or gas.
