Air coupler types

Couplers come in three basic flow sizes, ¼, ⅜, and ½ inch. It's easy to confuse flow size with thread size, but flow size refers to the inner diameter, which affects the SCFM, and is not related to thread size. You can get the same flow size with different thread sizes, so you must be careful.

What is the most common air fitting type?

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 is AV style air coupler?

V style couplers and plugs offer a maximum pressure of 300 PSI and air flow of 74 SCFM. Use for connecting air tools to an air hose or any pneumatic system components. Brass corrosion resistant couplers and steel plug. Designed to fit 1/4 in. NPT quick-connects.

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.

What is the standard air fitting size?

Most standard air compressors require a plug with a 1/2-inch or 1/4-inch flow size, with the latter being more common. Just like couplers, plugs come in automotive, industrial, ARO and V-style designs.

How do you measure a coupler?

Calculating The Inside Diameter With A Digital Caliper

Place the inside tips of the caliper on the inside of the bowl (coupling)
Expand the tips of the caliper until they're fully extended to the bowl size.
This will give you the correct size of the bowl needed.
1.75 is equivalent to a 1 3/4 size bowl.

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.

What are pneumatic fittings called?

Pneumatic push-in fittings, also known as push fittings, are the standard on the pneumatic fittings market and are the most widely used. They are characterized by the easy release function for the tube, i.e. by actuating a releasing ring.

Should I use Teflon tape on air fittings?

Should I use Teflon tape on air fittings? It is a good idea to use Teflon/PTFE tape on threaded fittings. Quick-release fittings are designed to seal using internal o-rings, so any additional sealant or tape is not required.

What is M style coupler?

Milton® M-Style® KWIK-CHANGE® couplers are made of brass, while M-Style® KWIK-CHANGE® plugs are made of case-hardened steel and are plated to resist rust. This collection of couplers and plugs: - Will interchange with all manufacturers who comply with the dimensional requirements of military specification MIL-C-4109.

What's better 3/8 or 1/4 air hose?

Inside Diameter Many people choose 1/4-inch hose because it's lighter than the 3/8-inch variety. It's easier to roll up, carry around and store. Of course, it doesn't hurt that the price tag for 1/4-inch hose is lower than its 3/8-inch counterpart. A wider inside diameter, however, can also have benefits.

What type of air fitting does ARB use?

Fittings are zinc nickel alloy electroplat- ed steel for corrosion resistance and strength. Use this to deliver air from your ARB compressor throughout your vehicle. 1⁄4 inch 2.0m long high flow stainless steel braided PTFE hose. Female JIC-04 37° flare fitting on each end.

How does an air coupler work?

By the female socket a seal is created and the air resumes its flow. The mechanical connection

What is a safety coupler?

Safety exhaust couplings are specially designed to prevent unintentional disconnection during operation and to avoid the whiplash effect when disconnecting.

What is the difference between automotive and industrial air fittings?

As you can see, Industrial style couplers have two striped going across the fitting, whereas the automotive style only has one. On the plug, the industrial style is slightly longer and different head than the automotive. Amflo also makes two Combo Couplers, one with a female end, and one with a male end.

What thread size are air fittings?

Thread sizes are typically 1/8", 1/4", 3/8", 1/2" or 3/4" pipe thread. A fitting that has female pipe threads (FPT) can only mate to something with male pipe threads (MPT) that are of the same pipe thread size. Nominal - the inner diameter size that the compressed air passes through.

What is the most common air compressor fittings?

The most common size fitting is ¼ inch. This is true for both ¼ and 3/8 inch air hose. Most 3/8 air hose comes with ¼ inch ends on it, thus most use a ¼ inch air fitting. Another important thing to consider when choosing the right size fitting is what size of thread is your air tool or air compressor.

How are fittings measured?

Measure the Outside Diameter (OD) of your pipe or pipe fitting:

Wrap a string around the pipe.
Mark the point where the string touches together.
Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
Divide the circumference by 3.14159.
