Harris 301 Regulator to 10mm Poly Tube Adapter Kit

Precision Adapter for Harris 301 Flowmeters

Optimize your welding gas setup with the 3-Piece Poly Tube Adaptor, specifically engineered for the Harris 301 Flow Regulator. In many advanced welding applications, particularly TIG welding and automated MIG processes, operators prefer 10mm polyurethane tubing for its flexibility, visibility, and resistance to kinking compared to traditional rubber hoses. This adapter kit provides the professional interface needed to connect such tubing directly to the regulator output without the need for intermediate couplers or unsafe friction fits.

The assembly consists of three precision components designed to work in unison: a threaded nut that matches the Harris 301 outlet, a tailpiece that inserts into the tubing for support, and a compression ring that seals the connection as the nut is tightened. This design ensures that the tubing is held firmly in place even under gas flow pressure, preventing accidental disconnections that could ruin a workpiece or waste expensive shielding gas like Argon or Helium.

Key Benefits:

• Direct Fit: Eliminates the need for multiple bushings or adapters; screws directly onto the Harris 301.
• Leak Prevention: The 3-piece compression style fitting provides a superior seal compared to standard hose barbs.
• Versatility: Enables the use of lightweight 10mm poly tubing for reduced torch drag and easier cable management.

Whether replacing a damaged fitting or configuring a new welding station, this adapter is a critical component for maintaining the integrity of your shielding gas envelope.
