Compression Parts Required
The LUBE USA 106292 KP-66 tubing coupler is designed for use with compatible compression parts on both ends. Select the proper compression nuts, compression sleeves, and tube inserts required for the type of 6mm tubing being installed.
Verify the tubing outside diameter, M10 × 1.0 threads, and compression-part compatibility before installation.
Straight Tubing Connection
The KP-66 provides a straight inline connection between two equal-size 6mm tubes. This configuration is useful when a lubrication line must be extended, repaired, or rerouted without replacing the entire tubing assembly.
Cut both tubing ends square and inspect them for damage before assembly. Correctly installed compression parts help provide a secure connection and support dependable 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-66 coupler, 6mm × 6mm tubing configuration, M10 × 1.0 connections, 29mm overall length, and 14mm 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 run. A secure inline connection helps minimize lubricant leakage, maintain consistent lubricant flow, and reduce equipment downtime during maintenance.
