48R359 - Surfox Replacement Polyethylene Tubing 4x6mm

Technical Overview of the Walter 48R359 Polyethylene Hose

The Walter 48R359 Polyethylene Hose is a specialized replacement component engineered specifically for use with Walter Surface Technologies' Surfox electrochemical weld cleaning systems. In the realm of industrial maintenance and repair operations (MRO), the integrity of fluid delivery systems is paramount, especially when handling reactive chemical agents. This hose is manufactured from high-grade polyethylene, a thermoplastic polymer selected for its excellent chemical stability and resistance to the acidic electrolyte solutions typically employed in the passivation and cleaning of stainless steel welds.

With precise dimensions of 4mm Inner Diameter (ID) and 6mm Outer Diameter (OD), this tubing ensures a leak-free connection between the electrolyte reservoir, the pump, and the cleaning wand. The dimensional tolerance is critical; even minor deviations in generic tubing can lead to poor seals, pressure drops, or hazardous leaks of phosphoric-acid-based fluids. The translucent nature of the polyethylene material provides an added layer of operational safety, allowing operators to visually verify fluid flow and detect the presence of air bubbles or blockages within the line without disassembling the system.

Polyethylene is inherently resistant to stress cracking and retains its flexibility across a reasonable temperature range, making it ideal for the dynamic environment of a welding shop where equipment is frequently moved and manipulated. Unlike rubber or lower-grade PVC which might degrade, harden, or swell upon prolonged exposure to Surfox electrolytes, the 48R359 maintains its structural integrity, ensuring consistent flow rates and preventing contamination of the cleaning fluid. This component is an essential spare part for maintaining the operational efficiency and safety standards of Surfox 104, 204, and other compatible units.

Key Technical Benefits

• Chemical Inertness: Specifically formulated to withstand prolonged exposure to electrochemical cleaning acids without degrading.


• Dimensional Precision: Exact 4mm x 6mm sizing guarantees compatibility with Surfox push-to-connect fittings and barbs.


• Durability: Resists abrasion and kinking during daily industrial use.
