Flared Union Swivel Elbows for 37° Flared Tube Fittings

Flared Tube Union Swivel Elbows

A flared tube union swivel elbow is a type of fitting used in piping systems to connect two tubes or pipes at an angle, allowing for directional changes in the flow of fluids, gases, or other substances. The design of the swivel elbow allows for rotational movement, providing flexibility in positioning and alignment.Here are the key features and components of a flared tube union swivel elbow:1. Flared Tube Ends: The elbow typically has flared ends on both sides, which are designed to connect to flared tubes or pipes. Flaring involves expanding the end of the tube outward, creating a conical shape that provides a secure and leak-resistant connection.2. Union Nut: The elbow includes a union nut, which is a threaded component that connects the two flared tube ends. The nut is used to tighten the elbow onto the tubes, ensuring a tight seal and preventing leakage.3. Swivel Connection: One of the unique features of a flared tube union swivel elbow is its ability to rotate or swivel. This is achieved through a swivel connection mechanism located between the union nut and the elbow body. The swivel allows for angular movement, making it easier to install and align the elbow in various configurations.4. Elbow Body: The main body of the swivel elbow is typically made of metal, such as brass or stainless steel, which provides strength and durability. The elbow body is designed to accommodate the flow of fluids or gases, with a curved shape that redirects the flow at a specific angle.Flared tube union swivel elbows are commonly used in applications where flexibility and alignment adjustments are required. They are often found in hydraulic systems, fuel lines, refrigeration systems, and other industrial or automotive applications. These fittings provide a reliable and convenient solution for connecting pipes or tubes at different angles while maintaining a secure and leak-free connection.

Installation of Flared Union Swivel Elbows:

The installation process for flared union swivel elbows involves a few key steps. Here's a general guide to help you understand the process:1. Prepare the Tubes: Ensure that the ends of the tubes you are connecting are clean, smooth, and free from any burrs or debris. Use a deburring tool or file if necessary to remove any rough edges.2. Flare the Tube Ends: If the tubes do not already have flared ends, you will need to flare them using a flaring tool. Follow the manufacturer's instructions for your specific flaring tool to achieve proper flares on the tube ends. This step is crucial as it ensures a secure and leak-free connection.3. Attach the Union Nut: Slide the Union nut onto one of the flared tube ends, making sure the threads align properly. Ensure that the nut is tightened securely but not overtightened, as it can damage the fittings or cause leaks.4. Connect the Elbow: Insert the flared end of the first tube into the swivel elbow body. Make sure it goes all the way into the fitting until it seats properly. Hold the elbow firmly in place.5. Swivel and Align: With the first tube connected, you can now swivel or rotate the elbow to the desired angle or alignment. The swivel mechanism allows for flexibility in positioning the elbow based on your specific requirements.6. Connect the Second Tube: Insert the flared end of the second tube into the other side of the flared union swivel elbows. Ensure that it is fully seated in the fitting.7. Tighten the Union Nut: Once both tubes are connected, use a wrench to tighten the Union nut onto the second tube's flared end. Again, be careful not to overtighten, as it can damage the flared tube fittings or cause leaks. The nut should be tightened enough to create a secure and leak-free connection.8. Test for Leaks: After installation, it's important to check for any leaks. Apply a soapy water solution or a leak detection spray to the connection points and look for any bubbles. If bubbles appear, it indicates a leak, and you should tighten the fitting further or make necessary adjustments.
