3M Speedglas Replacement Face Seal for 100 Air Series Helmets

Stay Safe and Comfortable with a Fresh Face Seal

If you are running a Speedglas 100 Air helmet, you know that the fresh air system is only as good as the seal keeping the bad stuff out. The Speedglas Face Seal (25-0099-28) is the direct replacement for your rig, designed to get your helmet back to factory-fresh performance. Welding all day with a torn or gross face seal isn't just uncomfortable—it's dangerous. If air is leaking out the sides, or worse, if fumes are leaking in, your PAPR isn't doing its job properly.

This replacement seal is made from soft, flame-resistant fabric that contours to your face without digging in, making those long shifts under the hood much more bearable. It creates that essential pocket of clean air, ensuring the breeze from your Adflo or regulator cools you down and keeps your lungs clear. We know that consumables wear out; sweat, sparks, and constant movement take their toll. Swapping out your face seal is one of the cheapest and easiest ways to maintain your gear and your health.

Don't rig up a temporary fix with duct tape or try to stretch the life of a crumbling seal. This genuine Speedglas part snaps right into place on your 100 Air shell. It’s designed to hold up against the heat and sparks you face daily. Keep a spare in your kit so you never have to compromise on safety when you're in the middle of a job.

Why Replace Your Face Seal?

• Hygiene: Old seals trap sweat and bacteria—start fresh.
• Safety: A tight seal is required to keep fumes out of your breathing zone.
• Comfort: New fabric feels better against the skin and reduces irritation.
• Performance: Ensures your air system maintains positive pressure effectively.
