What are the two types of air couplings?
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 are two types of couplings used in fire service?
There are three types of hose couplings, including threaded couplings, storz-type couplings, and non-symmetrical quick connect couplings. Threaded couplings are one of the commonly used in the fire service. They are a male/female set designed for use on most fire hose up to 3 inch in diameter.
What is Chicago hose?
A Chicago fitting (also called a Duck’s foot fitting due to its shape) is a one quarter turn fitting used for attaching hoses or piping together. Chicago fittings are used on both low to medium pressure gas and fluid lines.

What type of coupling do we use on air hoses?
A pneumatic coupling is used to connect compressed air tools to a compressed air line. A pneumatic coupler allows a tool to be easily connected or disconnected to a hose or pipe while it is under pressure.
What is the difference between NH and NPSH?
NH = NST. Fire hoses with National Pipe Straight Hose Thread (NPSH) has the same threads per inch as National Pipe Thread (NPT) but the threads do not taper. This allows a female coupling to thread onto a NPT fitting without being a permanent connection.
What is a BIC coupling?
FirstRESPONSE fire hose couplings are fitted onto the ends fire hose to enable the fire hose to be connected to a fire hydrant and also allow other firefighting equipment, such as nozzles, to be attached for the purpose of fighting a fire.
What does ARO stand for?
ARO stands for “after receipt of order.” It means the timeline for payment starts from the time you place the order, not the time the goods are shipped or received.
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.
