This fitting is commonly used to extend, repair, or reconnect lubrication lines in centralized lubrication systems.
Applications
- Centralized lubrication systems
- CNC machines and machining centers
- Repairing damaged tubing lines
- Extending lubrication tubing runs
👉 Couplers (union fittings) are used to connect two tubing sections together in-line, allowing easy system repair or expansion
Key Features
- Connects two 4mm (5/32”) tubing lines
- Dual 5/16-24 compression connections
- Straight union design for in-line connections
- Compatible with compression sleeves and tube inserts

Why This Part Matters
In lubrication systems, tubing can become damaged, worn, or require extension.
Without a coupler:
- Tubing must be replaced entirely
- Repairs become more difficult
- Downtime increases
This union fitting allows you to quickly connect two tubing sections, restoring system function without replacing the entire line.
When to Use This Coupler
- When repairing a broken or damaged line
- When extending lubrication tubing
- When modifying or rerouting a system
- During maintenance or system upgrades
