What are the different sizes of air compressor fittings?

Air hoses are measured by their internal diameter (ID), and come in standard sizes of ¼”, ⅜” or ½” or metric sizes of 6mm, 8mm, or 10mm. Since higher ID correlates to higher air capacity, selecting your ideal air hose diameter requires an understanding of the CFM needs of your air tools.

What is a Nitto fitting?

Fluid couplings are indispensable in providing connections in systems that involve the flow of air, water, oil, or gas. Nitto Kohki couplings are distinguished by their high quality and durability. Nitto Kohki couplers provide quick and easy connection/disconnection of fluid lines such as water, oil, gas, and air.

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.

Are all air hose fittings the same size?

Can air fittings be used for water?

Push-in fittings are used in all types of compressed air systems, but are most commonly used in applications having pneumatic cylinders, tools, and equipment. They can be used for water applications, but extra measures have to be taken (controlled surge pressure, water compatibility, insert ring, etc.)
