Air fittings types

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.

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 thread 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.

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 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 are the types of quick connect air fittings?

There are several types of quick connect fittings. ... Some of the most commonly used ones are:

Push to connect.
Ball and sleeve. ...
Cam-lock. ...
Luer lock. ...
Twist or bayonet.

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.

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 air fitting does ARB use?

US Industrial Standard (ISO 6150 B) female to ¼ x 18 NPT male fitting. Use this to connect an ARB high temperature inflation hose to the ¼ NPT port of an ARB Compressor, tank, or manifold kit.

How do I identify a thread type?

To identify whether the thread is tapered or parallel, look at the diameter of your thread. If the thread diameter gets thinner towards the end, you are looking at a tapered thread. On the contrary, if the thread diameter is the same at the top and the bottom of the thread, you have the parallel thread.

How many types of threads are there?

There are three standard thread series in the Unified screw thread system that is highly important for fasteners: UNC (coarse), UNF (fine), and 8-UN (8 thread).

What are thread sizes?

Thread sizes in inches are specified by diameter and threads per inch. For example, in the screw size 10-24, the first digit refers to the thread diameter, the and second digit is threads-per-inch (TPI). When the diameter smaller than 1/4”, the value is indicated by a number, like #1 or No. 1.

How tight should air fittings be?

So how do I tighten an air fitting?

Screw in the fitting until it is finger-tight, then.
use a wrench to give it another one-and-a-half turns.

How many times do you wrap Teflon tape?

When applying the tape clockwise, it's recommended that you wrap it around the thread three or four times. This is thick enough to prevent leaks, but not too thick that you can't get the nut on.

When should you not use PTFE tape?

An important thing to remember is that PTFE tape should not be used when connecting PVC fittings or valves with a female (FPT) thread. If the tape is used on female connections, a wedging action can occur which will cause major stress on the joint during assembly. PTFE tape does not guarantee a leak free 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.

How does an air coupler work?

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

Are air hose fittings universal?

Air compressor hoses are universal in their use of connecting the air compressor and tools. While hoses are universal in use, there are other variables to consider when shopping for an air compressor hose. Different applications and different tools may require different styles and types of compressor air hoses.

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.

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.
