Description

Product Overview

The LUBE USA 186211 tubing coupler is a male-thread union fitting designed to connect 4mm lubrication tubing while interfacing with threaded components in the system. It allows two tubing sections to be joined while also providing a threaded connection point for integration into lubrication circuits.

This makes it ideal for both system repairs and layout modifications.


Applications

  • Centralized lubrication systems
  • CNC machines and machining centers
  • Connecting tubing to threaded ports or adapters
  • Repairing or modifying lubrication lines

👉 Couplings are used to connect tubing runs and integrate them with system components in lubrication systems


Key Features

  • Connects two 4mm (5/32”) tubing lines
  • Includes threaded interface (M8×1) for system integration
  • 5/16-24 compression connections for tubing
  • Combines tubing connection and threaded mounting in one fitting
  • Compatible with compression sleeves and tube inserts
  • Ideal for repairs, extensions, and system modifications
  • Durable construction for industrial use

Why This Part Matters

In lubrication systems, some connections require both tubing-to-tubing joining and integration with threaded components.

Without the correct coupling:

  • Tubing cannot connect properly to system ports
  • Repairs become more complicated
  • System flexibility is limited

This fitting allows you to connect tubing while also tying into threaded system components, improving installation and serviceability.


When to Use This Coupler

  • When connecting tubing to threaded system components
  • When modifying or expanding lubrication systems
  • When repairing damaged lines that require threaded integration
  • When adapting between tubing and component connections

  • Part Number: 186211
  • Type: Male thread coupling / union
  • Tubing Size: 4mm (5/32”) × 4mm (5/32”)
  • Compression Thread: 5/16-24
