Several manufactures have recognized how confusing the many different types of plugs and couplers can be and have adopted a color-coded system. The reason for this is because plugs and couplers from the same manufacturer are more likely to fit better and be less prone to leakage than mixing brands, styles, or using universal couplers. It’s a solid brand that I can get locally, V-style connectors have less restriction, and the couplers work with the most different styles of plugs.
Despite their compact size air hose fittings and connectors play a very important role in the overall performance of air compressors and the air tools that they are used with. Our superb air tool fittings and couplers can enable you to extend your air supply and/or help you create more complex air systems to suit your needs. “Most hoses come supplied with either a thread fixing or quick release coupling. A male thread would screw into a female thread, whereas a male quick release would plug into a female quick release, so you may need a coupling to connect lines together. Fortunately, we supply a wide range of couplings, and any SGS air compressor or hose would use a ¼” BSP thread or quick release coupling to keep things simple.
For durability, you need to look at the plug materials and the internal seals in the coupler. The couplers need to utilize an o-ring seal that seats on the barrel of the plug. Now push-button safety coupling and universal coupling are also good choices.
There are two main types of air compressor couplers : Automotive and Industrial. As you can see, Industrial style couplers have two striped going across the fitting, whereas the automotive style only has one. Combo Couplers will fit either automotive or industrial style.
If you own an air compressor it’s likely that at some point you will need to replace the air hose fittings, and so, all the different types of compressor hose fittings and sizes must be understood to ensure you know what to buy! If you have threaded an airline connector into the supply port of each of your air tools, which is what you want to do to be able to connect a compressed air supply to each quickly and as needed, those connectors allow the quick connection of any air tool to a mating coupler on an air hose. If you are using an air drill or grinder or air nailer or any air tool that has its connector plugged into a coupler on the air hose, it is almost impossible not to impart a sideways motion to the coupler-connector connection as you are using the tool.
Committed to crafting quality pneumatic supplies, its focus on research and development shows in the success of the air fittings it retails. Air Hose Fitting Pricing$10 to $20: Most air fittings list between $10-$20. Price isn’t always reflective of quality, as many offerings near $20 include more pieces or accessories. If you have a damaged air hose fitting, the best course of action is to replace it.
Quick Connect Couplings are a fast and easy means of joining various pneumatic and fluid transfer lines. An automatic shut-off valve in the coupler end allows the quick connects to be disengaged without needing a separate ball or line valve. A short lead-in or whip hose coupled with solid male NPT ends will prolong coupler life as it will absorb vibration and reduce metal fatigue.
air compressor quick connect types Related Question:
What type of quick-connect for air compressor?
If you want to connect your air hose with your air compressor, quick disconnect couplers are a good option. Also known as quick release couplings, they provide a quick way to attach piping, with air fitting tools. They make air fittings simple so that the parts can be fitted by hand rather than by machine.
What are the two types of air couplings?
With a manual coupler, you have to pull back the sleeve to insert the plug and make the connection, but with an automatic coupler you just have to push the plug into the coupler and it will automatically make the connection. With both types you still need to pull back the sleeve to release the plug.
Are all air compressor quick connects the same size?
Size: another question that is often asked is what size of quick connect fittings does a person need? 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.
Are quick-connect fittings universal?
Universal interchange quick-connect air couplings are designed to work with other interchanges accepting multiple styles of nipples, including industrial, Tru-Flate, and ARO. The push-to-connect style has a protective sleeve that slides forward until the plug ejects.
What are the different styles of air fittings?
There are many different types of air fittings but most air tools use one of just a few types of connector. The main things to consider are the fitting type and the thread size. Common fixing types include ¼” BSP, ¼” PCL and 3/8” NPT.
Does hose size matter on air compressor?
Simply speaking, the larger the hose I.D, the more air it’ll be able to carry. While the external diameter of air hoses will vary wildly depending on the quality of the hose and the material it’s made from, common internal sizes of air hose are 6mm, 8mm and 10mm internal diameter.
What is the difference between industrial and automotive 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.
How are quick connect fittings measured?
Lay the hose over a ruler or tape measure. If the hose is 5/8” wide it is a 3/8” ID hose. If the hose measures ¾” wide, it is a 1/2” ID hose. (2) Measure the internal diameter of the quick disconnect.
Are all compressor fittings universal?
While some highly specialized environments or job requirements might call for special hose materials or fitting sizes, by and large, the air compressor hoses used in home and small shop environments are universal. These must all be considered when selecting an air hose for your compressor.
Can you use air quick connect 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.
Are industrial and automotive air fittings interchangeable?
Fortunately, a universal coupler (the female socket) will usually accept the two most popular male fittings, industrial and automotive, commonly available in home centers and hardware stores.
Are all hydraulic quick connect fittings the same?
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 1/4 quick-connect?
PRO-Fit Quick Connect fittings are designed to connect refrigerant lines without an open flame, brazing, or swaging. They are suitable for joining refrigerant lines in seconds after cutting the line, deburring the ends, and push to connect.
How is hydraulic quick-connect measured?
Measure the diameter of the thread If you are measuring the male half of the coupling (external thread) make sure you use the bottom clamps of the caliper, and if you are measuring the female half of the coupling (internal thread) use the top clamps of the caliper to get the right measure.
What size threads are air compressor 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.
