Compression Parts Required
The LUBE USA 106021 EA4-20 elbow adapter is designed for use with compatible compression parts on the 4mm tubing connection. Select the appropriate compression nut, compression sleeve, and tube insert for the tubing material being installed.
Verify the tubing outside diameter, M8 × 1 compression connection, R1/8 male thread, and compression-part compatibility before installation to ensure a secure, leak-resistant connection.
90-Degree Elbow Configuration
The EA4-20 provides a 90-degree transition between 4mm lubrication tubing and an R1/8 threaded lubrication port. This configuration is ideal where space is limited or where tubing must change direction without creating tight bends.
Using the proper elbow adapter helps simplify tubing routing, reduce stress on the tubing, and maintain consistent lubricant delivery throughout the lubrication system.
Dimensional Drawing
A dimensional drawing is included with this product to help verify the tubing size, thread specifications, elbow dimensions, hex size, and installation clearance before ordering.
Review the dimensional drawing and confirm that the EA4-20 adapter, 4mm tubing connection, M8 × 1 compression thread, R1/8 male thread, 20mm L1 dimension, 8mm L2 dimension, and 14mm hex match your lubrication system requirements.
Why an Elbow Adapter Matters
A properly selected elbow adapter provides a secure change in tubing direction while helping prevent kinks and unnecessary strain on the lubrication line. Correct fitting selection helps reduce leakage, maintain dependable lubricant flow, and improve the long-term reliability of centralized lubrication systems.
