Flare nuts are versatile hardware components commonly used in plumbing, automotive, and other mechanical applications. These nuts are specifically designed to provide a secure and leak-free connection between pipes, fittings, and equipment.One of the primary functions of flare nuts is to connect flared tubing or pipes. They are typically used in conjunction with flared fittings, which have a conical end that creates a tight seal when compressed against the flare nut.
In the automotive industry, flare nuts are commonly used in the brake and fuel systems. They allow for the secure attachment of brake lines, fuel lines, and hydraulic hoses to various components such as calipers, cylinders, fuel pumps, and filters. The tight and leak-free connections provided by flare nuts are critical for the safe and efficient operation of these systems.
Flare nuts also find applications in plumbing and HVAC systems. They are used to connect pipes and fittings in gas lines, water lines, and refrigeration systems. The reliable seal created by the flare nut helps prevent gas or water leaks, ensuring the integrity and efficiency of the plumbing or HVAC system.
Beyond their primary function, flare nuts can also serve other purposes. They can be used as a locking mechanism to secure other fasteners, such as bolts or threaded rods, in place. Additionally, flare nuts can be repurposed in various DIY or custom applications where a secure and tight connection is required.
