12 best compression fitting tube inserts

Compression fitting tube inserts are essential components used in compression fittings, particularly in the field of hydraulics, pneumatics, and plumbing. These inserts play a crucial role in creating secure and leak-free connections between tubes or pipes and various fluid systems. Here's what you need to know about compression fitting tube inserts:

Purpose: Compression fitting tube inserts are used to provide support and reinforcement to the tubing or pipe within a compression fitting assembly. They are placed inside the tube or pipe before the compression nut and ferrule (compression ring) are tightened to create a tight seal.
Material: These inserts are typically made from durable materials such as brass, stainless steel, or plastic, depending on the specific application and the compatibility with the fluid being transported.
Shape and Design: Compression fitting tube inserts are often cylindrical or tubular in shape, designed to fit snugly inside the tube or pipe. They may have various internal profiles to improve their grip on the tubing and enhance the sealing effect.
Function: The primary function of a tube insert is to support and reinforce the tubing's walls when the compression fitting is tightened. This prevents the tubing from collapsing or deforming under pressure, ensuring a secure connection.
Leak Prevention: Tube inserts also help prevent leaks by distributing the compression force evenly across the tubing or pipe. This even distribution of force ensures that the ferrule creates a reliable seal against the fitting body, minimizing the risk of fluid leakage.
Size and Compatibility: Tube inserts come in various sizes to match the diameter and material of the tubing or pipe being used. It's crucial to choose the correct insert size to ensure a proper fit and seal.
Installation: To install a compression fitting tube insert, slide it inside the tubing or pipe before inserting the tube into the compression fitting body. Ensure that the insert is centered and that it extends slightly beyond the tube's end.When the compression nut is tightened, it compresses the ferrule against the insert and tubing, creating a tight and secure connection.
Applications: Compression fittings and tube inserts are commonly used in hydraulic systems, pneumatic systems, and plumbing applications where a reliable and leak-free connection is essential. They are often used with copper, brass, stainless steel, or plastic tubing.
Maintenance: Regular inspection of compression fittings and tube inserts is important to ensure they are functioning correctly. Any signs of wear, damage, or corrosion should prompt replacement to maintain the integrity of the connection.

Compression fitting tube inserts are vital components in fluid systems, as they help ensure the safety and efficiency of fluid transport. Proper installation and selection of the right insert for the application are crucial for leak-free and reliable connections.

Parker Hannifin 63PT-6-62 Brass Insert Compress-Align Fitting, 0.62 Tube Well, 3/8" Compression Tube x 3/8" Compression Tube

Parker Hannifin Corporation

Check latest price

Product description

Parker's economical compress-align fittings are pre-assembled with a captive sleeve which is always Oriented Correctly for faster assembly. The captive sleeve gives a visible inspection before and after installation and the design of the sleeve aligns to seal even out-of-round tubing. Compress-align can be used in many areas where flare fittings are used due to the higher pressure rating, meaning no flaring, soldering or tube preparation resulting in faster installation. Compress-align bodies are interchangeable with standard compression bodies so inventory is decreased.
