Description
Product Overview
The LUBE USA 166054 EA4-8B Elbow Adapter is designed for connecting 4mm main tubing or tail tubing to lubrication points using compatible compression parts. Its 90-degree elbow configuration allows lubrication tubing to be routed in areas where a straight connection may not provide sufficient clearance.
This genuine LUBE USA metric adapter is suitable for centralized lubrication system installation, repair, and maintenance on industrial machinery, machine tools, CNC equipment, food processing equipment, packaging machinery, and automated manufacturing systems.
Applications
- Centralized lubrication systems
- Main lubrication tubing connections
- Tail tubing connections to lubrication points
- Installations requiring a 90-degree tubing connection
- Industrial machinery
- Machine tools and CNC equipment
- Food processing equipment
- Packaging and manufacturing equipment

Compression Parts Required
This elbow adapter is designed to connect tubing through compatible compression parts. The correct compression nut and compression bushing should be selected according to the tubing size and lubrication system configuration.
Confirm that the connected compression components are compatible with 4mm O.D. tubing and the M8 × 1 adapter thread before installation.
Dimensional Drawing
A dimensional drawing is included with this product to help verify the elbow configuration, tubing size, thread sizes, overall dimensions, and installation clearance before ordering.
Review the dimensional drawing and confirm that the EA4-8B adapter, 4mm tubing connection, M8 × 1 thread, and M8 × 1.25 tapered thread match your lubrication system.

Why an Elbow Adapter Matters
An elbow adapter allows lubrication tubing to change direction without sharply bending or kinking the tube. Proper routing helps protect the tubing, maintain lubricant flow, reduce stress on the connection, and provide a cleaner installation in confined machinery spaces.
