A female thread to metric tubing elbow allows a male threaded fitting to connect to the elbow fitting.įemale to Female elbows have the primary function of connecting two male threads together in a elbow shape.įlow Control Elbows control the flow rate through the fitting and can be used to adjust the actuation speed. This type of fitting is similar to the above type of fitting, with the sole difference of there being a female thread rather than male. The pneumatic fitting fits into the thread (with PTFE tape), and pneumatic tubing can connect to this fitting via the push-in socket. actuator, filter) will usually have a female thread socket. They connect a pneumatic component to pneumatic tubing. These are the most common type of pneumatic elbow fittings. In pneumatics, they can be metric tubing to metric tubing, (6mm to 6mm) or thread to thread (1/8” to 1/8”). One type of elbow fittings are union elbows, sometimes known as equal elbows, whereby both ends of the elbow are of the same size. Imagine a cylinder mounted for use, would a male stud whereby the tubing has to exit directly, be appropriate? Union Elbows This is so that they can connect pneumatic components (actuators) with the air line in a non-obstructive manner. Elbow Fitting - Push-In Port to Male ThreadĮlbow Fittings are shaped at 90-degree angles. They are 2.1 Elbow Fittings ( Shop Elbow Fittings)įigure 3. Male Studs and Female Studs (sometimes called Straight Connectors) are the simplest type of pneumatic fitting. Quick couplings usually have 2 (though, sometimes, 3) components to join two independent tubing together. In contrast to push-in fittings, pneumatic quick couplings can also be convenient (and safer) as inline pressure will not need to be reset to 0 before every reconnection. A quick press on the release ring will release tubing, whilst a sturdy thrust of tubing into the fitting will engage the lock jaws, securing the tubing for pneumatic system use. Secondly, sometimes, components will need to be easily disconnected and reconnected. This is the first function of pneumatic fittings. tubing) means some adaptor or fittings will need to be used. The lack of threading on pneumatic lines (i.e. This presents both start-up engineering and cost savings, and is one aspect where pneumatics reign supreme over hydraulics. Unlike hydraulics, it is not feasible for the airline to have threads built in. The majority of pneumatic components have threaded connections whilst pneumatic tubing does not have threads, but are rather of a specific outer diameter (OD) size (usually metric, though sometimes imperial). Consider the need for adjustment of connection type. Whilst the most obvious function of pneumatic fittings is to connect pneumatic components (actuators, valves, filters, air treatment) together, there are more nuances to this than at first glance. In this article, we will examine all the different types of pneumatic fittings and their usage. And, a male stud is typically used on a pneumatic acutator with a threaded port, so that tubing can be connected to it. For exampe, bulkhead connectors are used to connect piping or tubing together through a panel. The larger the tank the longer you can sustain that working pressure.Ī small compressor like that most likely will not be able to create pressurized air fast enough to keep up with the consumption of a tool that is capable of draining a lot of air like that.The different types of pneumatic fittings have different functions. How long you can maintain that pressure depends on how big your air tank is. But you will also get more performance out of the tool for the duration that you can maintain your 90 PSI working pressure. You will use considerably more air at 90 PSI working pressure with a G style compared to your standard A style. Running bigger fittings means you can flow more air at the same working pressure. Once you go below 90 PSI your tool will begin to lose power.
Your impact gun will work at its same performance level until you run out of enough air to supply at 90 PSI. So let's say your impact gun runs at 90 PSI. 5 gallons is rather small, but basically it will in theory improve Preformance until you no longer can supply air at the tools working pressure.
