Description
Product Overview
The LUBE USA 186251 compression nut is used to secure 4mm tubing in centralized lubrication systems. It threads onto compression fittings such as adapters, junctions, and valves, tightening the connection and creating a reliable seal.
This nut is a key component in compression fitting assemblies, ensuring proper tubing connection and system performance.
Applications
- Centralized lubrication systems
- CNC machines and machining centers
- Tubing connections to adapters, junctions, and valves
- Maintenance and repair of lubrication lines
👉 Compression nuts are used to secure tubing connections in lubrication systems, helping ensure proper sealing and function
Key Features
- 5/16-24 thread for standard compression fittings
- Designed for 4mm (5/32”) tubing
- Applies compression force to create a tight seal
- Prevents leaks and maintains system pressure
- Compatible with compression sleeves and tube inserts
- Durable construction for industrial environments
Why This Part Matters
In a lubrication system, connections must be tight and secure to maintain pressure and proper oil flow.
Without a compression nut:
- Tubing cannot be secured properly
- Leaks will occur
- System pressure will drop
This nut provides the force needed to compress the sleeve around the tubing, creating a leak-free connection.
When to Use This Compression Nut
- When installing lubrication tubing
- When assembling compression fittings
- When replacing worn or damaged nuts
- During system repair or maintenance
