ARO Air Fittings Quick Release Couplers LU6-2

ARO quick connect air fittings connect air tools and hoses to compressed air supplies. Also known as Milton A-style couplings, they are used on pneumatic lines in furniture building, construction, and factory automation.

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.

Air Fittings vs Hose Connectors  and Quick Release Couplers

WHAT IS BSPF AND BSPM?

The British Standard Pipe (BSP) is a family of standard screw thread types that is used internationally for interconnecting and sealing pipe ends by connecting male with female threads. The thread size is measured and based on the inside of the hose fitting. When couplers are labelled as "Female Quick Release Coupler to 1/4" BSPM" the BSPM translates to British Standard Pipe Male. In turn "F" appears if the coupler connects to female.

WHAT ARE QUICK RELEASE COUPLINGS?

Quick-release couplings allow you to easily connect and disconnect airlines from either the air compressor or air tool. As mentioned above, quick couplings are designed to seal when disconnected via an internal o-ring, eliminating the need for a shut-off valve. These connections are made up of a male part and a female part which contain the internal pressures when properly connected.The connection also allows the joint to move, meaning less kinking and twisting of the hose, better suited for a busy workplace, to keep the area safe.

WHAT TO CONSIDER WHEN CHOOSING YOUR COUPLING?

1.The type of coupling you need. Is it ¼” BSP, ¼” PCL or another type?
2.The maximum pressure (in PSI) the air coupler/plug can withstand
3.Some couplers require the use of PTFE tape to form a seal
4.Couplers may come with different temperature ratings

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. The fittings maintain a constant flow of air and pressure within the hoses so that the performance of the air tools is not compromised. Having durable and reliable air tool fittings and air tool couplers is hugely important for the safe and efficient operation of your air tools.

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. To ensure the equipment is in its optimal working condition the fittings must be kept in good working shape.Contact us to get your Aro Air Fittings!
