Compression Parts Required
The LUBE USA 106201 KP-44 tubing coupler is designed for use with compatible compression parts on both ends. Select the correct compression nuts, compression bushings, and any tubing support components required for the type of 4mm tubing being installed.
Verify the tubing outside diameter, M8 × 1.0 threads, and compression-part compatibility before installation.
Straight Tubing Connection
The KP-44 provides an inline connection between two equal-size 4mm tubes. This configuration is useful when a lubrication line must be lengthened or repaired without replacing the entire tubing run.
Cut tubing ends square and inspect them for damage before assembly. Properly installed compression parts help create a secure connection and support consistent lubricant delivery.
Dimensional Drawing
A dimensional drawing is included with this product to help verify the tubing sizes, thread specifications, overall length, hex size, and required installation clearance before ordering.
Review the dimensional drawing and confirm that the KP-44 coupler, 4mm × 4mm tubing configuration, M8 × 1.0 connections, 25mm overall length, and 10mm hex match your lubrication system requirements.

Why a Tubing Coupler Matters
A properly selected tubing coupler allows a lubrication line to be extended or repaired without replacing the complete tubing assembly. A secure inline connection helps prevent lubricant leakage, maintain consistent lubricant flow, and reduce machinery downtime during maintenance.
