48.0005.0170 - Fronius Ceramic Insulating Sleeve 4.3mm x 5.3mm x 16mm

Precision Fronius Ceramic Insulation

The Fronius Ceramic Sleeve 4.3 / D= 5.3 X16 (Part Number: 48.0005.0170) is a critical component designed for the exacting standards of Fronius welding systems. In the realm of precision welding, particularly with TIG and advanced MIG processes, the integrity of the torch assembly is paramount. This ceramic sleeve serves as a vital insulator, separating electrically charged components from the torch body or other conductive parts, thereby preventing unwanted arcing and ensuring the safety and stability of the welding arc.

Manufactured from high-grade technical ceramic, this sleeve is engineered to withstand the extreme thermal shock and continuous high temperatures inherent in industrial welding applications. Unlike inferior materials that may crack or degrade under thermal cycling, Fronius ceramics are formulated for longevity and structural integrity. The dimensions are machined to tight tolerances—specifically an inner diameter of 4.3mm, an outer diameter of 5.3mm, and a length of 16mm—to ensure a seamless fit within the compatible torch head. This precision prevents movement or misalignment that could disrupt gas flow or electrode positioning.

Using genuine Fronius parts like this ceramic sleeve ensures that your equipment operates at peak performance. The dielectric strength of the ceramic material provides robust electrical isolation, which is essential for maintaining the purity of the arc and protecting the welder and the machine. Whether used in manual fabrication or automated welding cells, this small but significant component plays a large role in the consistency of your weld output. Trust in the engineering excellence of Fronius to keep your operations running smoothly with high-quality replacement parts.

Regular inspection of torch consumables is recommended. If you notice cracks, chips, or excessive buildup on your existing insulating sleeve, immediate replacement with this OEM part is advised to avoid potential damage to the torch neck or degradation of weld quality. Invest in the reliability of your welding setup with the Fronius 48.0005.0170 Ceramic Sleeve.
