3M Speedglas 9100 Replacement Headgear Assembly

Restore Comfort and Stability to Your 9100 Hood

There is nothing more frustrating than a welding helmet that won't stay put. If you are constantly nodding your head to keep your hood down, or if you find yourself readjusting your helmet every five minutes, it is time to replace your headgear. The Speedglas 9100 Headband Assembly (06-0400-51) is the direct replacement for your tired, worn-out suspension. Designed to fit all Speedglas 9100 and 9100FX series helmets, this assembly brings back the 'like-new' feel of your premium hood, ensuring it stays exactly where you need it, whether you are welding flat, horizontal, or overhead.

Speedglas is famous for its headgear design for a reason: it is built around the human head, not just a plastic mold. This replacement assembly features the signature smooth ratchet knob at the back, which is large enough to operate easily even with TIG gloves on. It allows you to dial in the perfect tightness—secure enough to hold steady, but not so tight that it gives you a headache by lunch. The unique dual crown straps let you adjust exactly how high or low the helmet sits on your head. This is a game-changer for visibility; getting the helmet to sit lower can often give you a better view of the puddle through the clear state of your lens. Plus, the included friction knobs let you set the 'snap' of the flip mechanism just the way you like it.

Don't suffer through a shift with a helmet that digs into your scalp or flops down unexpectedly. This kit includes everything you need: the headband, the forehead strap, the back pad, and the mounting hardware. It is a quick swap that takes less than five minutes but makes a massive difference in your daily comfort. Keep your focus on the arc, not on your gear, by refreshing your 9100 or 9100FX with this genuine Speedglas suspension system.
