3M Versaflo M-Series Replacement Head Insert

Keep Your Cool with the 3M Versaflo M-170 Replacement Insert

If you run a 3M Versaflo rig, you know that comfort is king. The moment your airflow starts acting up or your helmet doesn't sit quite right, your day gets a lot longer. The 3M M-170 Head Insert is the replacement part you need to get your M-Series headtop back to feeling brand new. This isn't just a piece of plastic; it's the skeleton inside your helmet that makes sure that fresh, cool air gets exactly where you need it—right across your face and visor.

Whether you are rocking the lightweight M-100 face shield for grinding or the heavy-duty M-400 helmet for serious welding and fabrication, this insert fits them all. It connects your suspension to the outer shell and helps guide the air from your PAPR blower. If your old insert is cracked, warped, or just seen better days, swapping it out is a quick fix that makes a huge difference. You don't need a degree in engineering to install it, either; it snaps into place so you can get back under the hood fast.

Don't let a broken internal part compromise your safety or your comfort. A damaged insert can lead to poor airflow, foggy lenses, and a wobbly helmet fit. By replacing the M-170, you ensure your gear stays balanced and your view stays clear. It’s a small part that plays a big role in keeping you welding, grinding, and working without the headache of malfunctioning gear.

Why You Need This Part

• Fixes Airflow Issues: Ensures air is directed over your face to keep you cool and your lens clear.
• Restores Fit: tightens up the connection between your headgear and the helmet shell.
• Versatile: Fits your M-200, M-300, or M-400, so it's a great spare to keep in the shop.
