Compression Parts Required
The LUBE USA 106002 SA4-20 straight adapter is designed for use with compatible compression parts on the tubing connection. Select the proper compression nut, compression sleeve, and tube insert when required for the tubing material being used.
Verify the tubing size, M8 × 1 compression thread, R1/8 male thread, and compression-part compatibility before installation.
Straight Connection Configuration
The SA4-20 provides a straight transition from 4mm lubrication tubing to an R1/8 female threaded port. The longer body length compared to the SA4-16 provides additional reach where installation clearance or fitting depth requires it.
LUBE USA designates R threads as male and Rc threads as female. Confirm that the receiving component is equipped with a compatible R1/8 female port before installation.
Dimensional Drawing
A dimensional drawing is included with this product to help verify tubing size, thread specifications, body dimensions, hex size, and installation clearance before ordering.
Review the dimensional drawing and confirm that the SA4-20 adapter, 4mm tubing connection, M8 × 1 compression thread, R1/8 male thread, 20mm body length, 12mm threaded section, and 10mm hex match your lubrication system requirements.

Why a Straight Adapter Matters
Selecting the correct straight adapter ensures a reliable connection between lubrication tubing and threaded system components. Proper installation helps minimize leaks, maintain consistent lubricant flow, reduce stress on tubing, and improve the long-term performance of a centralized lubrication system.
