DK-Lok Tube Fittings provide dependable, leak-free connections in piping systems and are designed to operate reliably even in high-pressure and high-temperature environments. With exceptional safety and durability, these fittings are essential components in various industries.
Double-Ferrule fittings are a type of compression fitting used in piping systems. They consist of the Front Ferrule and the Back Ferrule, which work together to securely grip the tube and create a tight seal to prevent leaks.
- · Body : The central part of the fitting, featuring threads that connect with tube.
- · Nut : Compresses the ferrules and is used to assemble or disassemble the fitting.
- · Front Ferrule : Contacts the tube’s outer wall, forming a seal and securing the tube.
- · Back Ferrule : Supports the Front Ferrule from behind and enhances the sealing force when the nut is tightened.
Assembly of each components
DK-Lok Tube Fittings operate through a simple yet highly effective mechanism. Simply insert the tube into the fitting body and tighten the nut by 1-1/4 turns—this is all that is required.
As the nut is tightened, the Back Ferrule pushes the Front Ferrule forward, gradually achieving both sealing and gripping. The Front Ferrule interacts with the internal taper of the fitting body, securely gripping the tube while eliminating any gaps. The Back Ferrule applies additional compression, ensuring a secondary seal for enhanced reliability.
This process guarantees a secure and leak-free connection, even in demanding conditions, as demonstrated in the reference below.
- · Single-Ferrule Fittings : Uses a single ferrule, simpler design
- · Double-Ferrule Fittings : Uses two ferrules for enhanced sealing
Single-Ferrule fittings offer easy installation and cost-effectiveness, making them ideal for standard applications.
In contrast, Double-ferrule fittings provide superior sealing and stability, ensuring reliability in critical industrial systems.
