48R540 - Walter Surfox Replacement PTFE Tubing 2mm x 4mm

Genuine Walter 48R540 PTFE Replacement Tubing

Maintain the peak performance of your electrochemical weld cleaning operations with the Walter 48R540 PTFE Tube 2X4. Designed specifically for the rigorous demands of the metalworking industry, this replacement tubing is an essential component for Walter Surface Technologies' renowned Surfox systems. When dealing with electrochemical cleaning, the integrity of your fluid delivery system is paramount. This tubing ensures that the electrolyte solution is delivered consistently and safely from the machine to the application wand, guaranteeing a perfect finish on stainless steel welds every time.

Superior Material Construction

The 48R540 is manufactured from high-grade Polytetrafluoroethylene (PTFE), commonly known as Teflon. This material is selected for its exceptional chemical inertness. Surfox systems utilize powerful electrolyte solutions to remove heat tint and passivate stainless steel; standard rubber or PVC tubing would quickly degrade, crack, or swell under exposure to these acids. The PTFE construction of this tube offers:

• Chemical Resistance: Completely impervious to the acidic electrolytes used in weld cleaning, ensuring no contamination of the fluid and no structural failure of the line.


• Thermal Stability: Capable of withstanding the heat generated during the electrochemical process without softening or deforming.


• Low Friction: The smooth interior surface prevents clogging and ensures a steady, non-pulsing flow of cleaning fluid.

Precision Fit for Surfox Systems

Using generic tubing can lead to leaks at connection points or improper flow rates that affect cleaning speed. The Walter 48R540 features precise dimensions of 2mm Inner Diameter (ID) and 4mm Outer Diameter (OD). This specific sizing is engineered to fit perfectly with the compression fittings and barbs found within the Surfox machine and wand assemblies. A tight seal prevents hazardous leaks of electrolyte solution, protecting both the operator and the internal electronics of the machine.

Maintenance and Longevity

Regular maintenance of your weld cleaning equipment extends its lifespan and ensures safety. Over time, physical wear and tear or accidental kinks can compromise tubing. Keeping a genuine Walter 48R540 PTFE tube in your maintenance inventory ensures that you can address any fluid delivery issues immediately, minimizing downtime. Whether you are repairing a damaged line or performing a scheduled overhaul of your Surfox unit, this OEM part restores factory-level performance to your fluid delivery system.
