OVERVIEW

Technical Overview of Walter 48R330 Polyethylene Hose

The Walter 48R330 is a specialized polyethylene (PE) hose designed primarily for use within the fluid delivery systems of Walter Surface Technologies' Surfox electrochemical weld cleaning machines. This component is critical for the safe and efficient transport of electrolyte solutions from the internal reservoir to the application wand. The tubing features precise metric dimensions with an inner diameter (ID) of 4mm and an outer diameter (OD) of 6mm, ensuring a leak-free seal when used with standard metric push-to-connect fittings or compression fittings found on Surfox units.

Polyethylene is selected for this application due to its robust chemical resistance properties. Surfox systems utilize phosphoric acid-based electrolytes which can degrade lesser materials over time. The PE construction of the 48R330 resists hydrolysis and chemical attack, maintaining structural integrity even with prolonged exposure to acidic fluids. This prevents brittleness, cracking, and subsequent leaks that could damage internal machine components or pose safety hazards to the operator.

From a maintenance perspective, using the correct OEM specification tubing is vital for maintaining the calibrated flow rates of the machine. The 4mm ID provides the specific hydraulic diameter required for the pump system to deliver the optimal amount of fluid to the cleaning pad. Deviations in diameter could lead to pump strain or insufficient fluid delivery, compromising the passivation process. This hose is supplied as a direct replacement part, meeting all original manufacturing tolerances for the Surfox product line.

Key Technical Specifications:

  • Material: Linear Low-Density Polyethylene (LLDPE) or similar industrial grade PE.
  • Dimensions: 4mm ID x 6mm OD.
  • Chemical Compatibility: Excellent resistance to acids, alkalis, and aqueous solutions.
  • Flexibility: Moderate flexibility for internal routing without kinking.

FAQ

This hose has an Inner Diameter (ID) of 4mm and an Outer Diameter (OD) of 6mm.

Yes, it is made of polyethylene which offers excellent chemical resistance to the acidic electrolytes used in Surfox systems.

It is compatible with most Surfox models that utilize 4x6mm tubing for fluid delivery. Check your parts manual to confirm the specific tubing size required.

This SKU typically refers to a specific replacement length or unit as defined by Walter. Please verify the specific quantity per pack, but it is generally supplied as a repair component.

OEM tubing ensures the exact dimensional tolerances for leak-free connections and the specific chemical resistance required for Walter's proprietary fluids.

The hose is usually used with push-to-connect fittings. Ensure the end is cut square and push it firmly into the fitting until it seats.

While specific pressure ratings depend on temperature, standard 4x6mm PE tubing is typically rated for low to medium pressure applications well within the range of Surfox pumps.

This tubing is often used for the internal fluid lines or the fluid line running alongside the cable, depending on the specific Surfox model configuration.
