48D418 - Walter 1/2-Inch ID x 36-Inch Replacement Hose Assembly

Technical Overview of the Walter 48D418 Hose Assembly

The Walter 48D418 is a specialized replacement hose assembly designed to meet the rigorous demands of industrial surface finishing and cleaning systems manufactured by Walter Surface Technologies. This component features a precise 1/2-inch inner diameter (ID), which is critical for maintaining the correct volumetric flow rate of fluids within the system. Whether used for transporting cleaning solutions in Bio-Circle parts washers or coolants in other finishing equipment, the internal geometry of this hose is engineered to prevent cavitation and pressure drops that could compromise machine performance.

With a total length of 36 inches, this hose provides the necessary flexibility and reach required for internal machine routing or external applicator maneuverability. The construction material is selected to offer chemical compatibility with Walter's proprietary range of industrial fluids, ensuring that the hose does not degrade, swell, or crack upon prolonged exposure to surfactants, degreasers, or coolants. This resistance to chemical attack extends the service life of the component and prevents contamination of the working fluid, which is essential for maintaining high-quality surface treatment results.

Important Supersession Notice: The 48D418 part number has been officially discontinued by the manufacturer and replaced by the updated part number 48D445. The successor part, 48D445, retains all the critical dimensional specifications—1/2" ID and 36" length—while potentially incorporating improvements in material composition or reinforcement technology to further enhance durability and pressure resistance. Maintenance personnel seeking the 48D418 should confidently procure the 48D445 as the direct, backward-compatible replacement authorized by Walter Surface Technologies.

When installing this replacement hose, it is recommended to inspect all connection points and fittings for wear or corrosion. A secure seal is vital to prevent fluid leakage, which can lead to safety hazards and environmental concerns in the workshop. The 48D418 (and its successor 48D445) is designed for a direct fit, minimizing downtime during maintenance intervals and ensuring that your Walter equipment returns to optimal operational status with minimal delay.
