Understanding the Essential Components of Banjo Fittings
Banjo fittings, versatile and indispensable in various industries, comprise a range of components that work together to ensure secure and reliable connections. Understanding these components is crucial for their proper installation, performance, and longevity.
Ferrule: The ferrule is a ring-shaped metal gasket that fits snugly over the flared end of a tube. It acts as a seal, preventing leaks when compressed by the banjo fitting’s nut.
Nut: The nut screws onto the banjo fitting’s body and compresses the ferrule, creating a leak-proof seal.
Body: The body of the fitting is the main housing that connects the fitting to the system. It typically has a hollow center and threaded ends.
Flare Nut: For flare-type fittings, the flare nut is similar to the nut but features a conical shape to mate with a flared tube.
Flared Tube: A flared tube has its end expanded to form a cone-shaped flange. When tightened against the flare nut, it creates a metal-to-metal seal.
Male Threads: Many banjo fittings have male threads on one end, allowing them to screw into female threads in other components.
Female Threads: Female threads are found on the other end of the banjo fitting, enabling connections with components that have male threads.
Pipe Dope: A sealant, such as pipe dope, is often applied to the threads of the banjo fitting to enhance the seal and prevent leaks.
Release Button: Some quick-connect banjo fittings have a release button that allows the fitting to be disconnected without the use of tools.
Collet: A collet is a tapered ring that secures the tube within the fitting.
Release Collar: For push-to-connect fittings, a release collar is used to disengage the fitting from the tube.
Check Valve: Check valves are used in certain banjo fittings to prevent fluid flow in one direction.
Swivel Nut: A swivel nut allows the fitting to rotate while maintaining a secure connection.
Union Nut: A union nut connects two banjo fittings together, providing a convenient way to assemble or disassemble the system.
