48R555 - Walter Surfox Replacement PE Tube 4x6mm - 9m Length

Technical Overview of the Walter 48-R-555 PE Tube

The Walter 48-R-555 is a specialized replacement Polyethylene (PE) tube designed for the fluid delivery systems of Walter Surface Technologies' electrochemical weld cleaning units, specifically those utilizing a detachable wand configuration. This component is critical for the safe and efficient transport of cleaning electrolytes from the main unit to the application tip.

Manufactured to precise metric tolerances, this tube features a 4mm inner diameter (ID) and a 6mm outer diameter (OD). These dimensions are calibrated to fit standard push-to-connect fittings and barb connections found on Walter Surfox wands, ensuring a leak-free seal that maintains system pressure. The 9-meter length provides ample reach, allowing operators to maneuver around large workpieces without moving the base unit, thereby improving workflow efficiency in industrial settings.

The material composition is high-grade Polyethylene, chosen for its excellent chemical resistance against the phosphoric and sulfuric acid-based solutions typically employed in electrochemical cleaning and passivation processes. Unlike standard pneumatic tubing, this PE tube resists hardening, cracking, and discoloration caused by prolonged exposure to aggressive electrolytes. Regular inspection and replacement of the fluid delivery tube are essential maintenance protocols to prevent hazardous leaks and ensure consistent electrolyte flow to the carbon fiber brush or tungsten tip.

Installation and Compatibility

This tubing is supplied as a continuous 9-meter coil, allowing it to be cut to length if necessary or used in its entirety for maximum reach. It is directly compatible with the detachable wand assemblies of the Surfox series. Technicians should ensure that all pressure is relieved from the system and the unit is powered off before attempting to replace the tubing. Proper seating of the tube into the wand and machine fittings is crucial to prevent fluid bypass.
