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

Keep Your Fronius Torch Running Smoothly

Maintain the reliability and safety of your welding equipment with the Fronius Ceramic Sleeve 4.3 / D= 5.3 X16. Identified by part number 48.0005.0170, this replacement sleeve is an essential consumable for welders who demand the best performance from their Fronius torches. Over time, the intense heat and harsh environment of the welding zone can take a toll on internal torch components. Ceramic insulators, while durable, can eventually succumb to thermal stress or physical impact. Replacing them promptly is key to preventing costly torch repairs down the line.

This sleeve acts as a protective barrier, providing electrical insulation and mechanical spacing within the torch head. With precise dimensions of 4.3mm ID, 5.3mm OD, and 16mm length, it is designed to drop perfectly into place without modification. A compromised insulator can lead to erratic arcs, short circuits, or even damage to the torch body itself. By using this genuine Fronius replacement, you ensure that the electrical current is directed exactly where it needs to go—to the workpiece—rather than arcing internally.

Welders Supply understands that downtime is money. That's why we stock high-quality OEM parts like this ceramic sleeve to get you back to welding fast. The ceramic material used by Fronius is specifically chosen for its high dielectric strength and resistance to thermal shock. This means it can handle the rapid heating and cooling cycles of tacking and long weld runs alike. It resists spatter adhesion better than many plastics or lower-grade composites, making it a long-lasting solution for busy shops.

Don't let a small, worn-out part compromise your weld quality or safety. Keep a few of these ceramic sleeves in your maintenance kit. Whether you are performing maintenance on a manual TIG torch or servicing an automated welding head, the Fronius 48.0005.0170 sleeve provides the fit and function you need. Order today and ensure your equipment continues to deliver the precision results Fronius is known for.
