Description
Product Overview
The LUBE USA 106271 tube insert (TI-4) is designed for use inside 4mm nylon tubing in centralized lubrication systems. It provides internal support to the tubing when used with compression fittings, helping create a secure and leak-free connection.
This insert is used in combination with a compression sleeve and nut to ensure proper sealing and system performance.
Applications
- Centralized lubrication systems
- CNC machines and machining centers
- Tubing connections to fittings and valves
- Compression fitting assemblies
π Tube inserts are used to reinforce tubing and improve sealing in compression connections
Key Features
- Designed for 4mm (5/32β) tubing
- Installs inside tubing to provide internal support
- Prevents tubing collapse during compression
- Improves sealing performance with compression fittings
- Compatible with LUBE tubing, sleeves, and fittings
- Durable brass construction for long service life
Why This Part Matters
Without a tube insert, nylon tubing can deform or collapse when compression fittings are tightened.
This can cause:
- Poor sealing
- Leaks
- Inconsistent lubrication
The tube insert reinforces the tubing from the inside, ensuring a proper seal and maintaining system reliability.
When to Use This Insert
- When installing 4mm nylon tubing
- When using compression fittings and sleeves
- When repairing leaking or damaged connections
- During system installation or maintenance
π Tube inserts are especially important when working with plastic tubing, not metal tubing
