Product Overview
The LUBE USA 186022 elbow adapter (EA4-25) is a 90° fitting designed to connect 4mm lubrication tubing to threaded components such as pumps, valves, and manifolds. It features a 1/8″ NPT male thread and a 5/16-24 compression connection for tubing.
This elbow design allows lubrication lines to change direction, making it ideal for tight spaces or complex system layouts.
Applications
- Centralized lubrication systems
- CNC machines and machining centers
- Connecting tubing to pumps, valves, and manifolds
- Routing lubrication lines around obstacles
👉 Elbow fittings are used to redirect tubing while maintaining a secure connection in lubrication systems
Key Features
- 90° elbow design for directional routing
- 1/8″ NPT male thread for standard connections
- 5/16-24 compression fitting for 4mm tubing
- Helps route tubing in tight or confined spaces
- Compatible with compression sleeves and tube inserts
- Durable brass construction (C3604) for long service life
- Provides a secure, leak-resistant connection
Why This Part Matters
In lubrication systems, routing tubing properly is just as important as making a connection.
Without elbow fittings:
- Tubing may kink or bend incorrectly
- Installation becomes difficult in tight spaces
- Connections may become stressed or leak
This elbow adapter allows you to redirect the line cleanly, maintaining proper flow and system reliability.
When to Use This Adapter
- When tubing needs to turn 90°
- When working in tight or confined spaces
- When routing lines around machine components
- When replacing or upgrading system fittings
