Compression Parts Required
The LUBE USA 106211 KPW-4 tubing coupler is designed for use with compatible compression nuts and compression sleeves for 4mm tubing. The compression parts secure the tubing at both ends of the coupler and help create dependable, leak-resistant connections.
Verify the tubing outside diameter and compression-part compatibility before installation.
Nylon Tubing Installation
When connecting nylon tubing, LUBE USA specifies the use of a compatible TI-4 tube insert. The insert supports the inside of the tubing and helps prevent deformation when the compression fitting is tightened.
Dimensional Drawing
A dimensional drawing is included with this product to help verify the tubing size, M8 × 1 connections, overall dimensions, hex size, and required installation clearance before ordering.
Review the dimensional drawing and confirm that the KPW-4 coupler, 4mm tubing connections, 27mm overall length, 8mm connection lengths, 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 entire tubing run. A secure inline connection helps prevent lubricant leaks, supports consistent lubricant delivery, and reduces downtime during machinery maintenance.
