This 10-pack of 271320 helmet front cover lens replacements is a third-party set of clear outside covers made for Miller Infinity helmets that use the 271320 front lens cover. Miller lists the OEM part at 6 x 5-5/8 inches. Buy it only after confirming that your helmet takes that cover, and remember it protects the auto-darkening filter rather than replacing it.

What the 271320 Helmet Front Cover Lens Does
The front cover is the outermost lens. It takes the sparks, spatter and grinding dust so the auto-darkening filter behind it stays clean. When the cover is scratched or pitted you can swap it in seconds; replacing the whole filter is a far bigger expense.
The cover is not a shade lens and gives no arc protection by itself.
Fit Check Before You Order
- Confirm that your helmet is a Miller Digital Infinity or Infinity model.
- Look up the front cover part number in the manual or on the old cover and make sure it says 271320.
- Measure the old cover; it should be close to 6 x 5-5/8 inches.
- Do not force a cover that does not match the holder.
How to Install a New Cover
- Remove the damaged cover following the helmet instructions and clear any debris from the holder.
- Peel the protective film from the new cover; leftover film can look like haze.
- Flex the cover gently into the holder until it seats on all sides.
- Check the fit and view before you weld.
Replace the cover when scratches, heat marks or stuck-on spatter get in your view.
Pros and Limitations
Pros
- Ten covers make the cover a routine replacement item.
- Size is clearly tied to a Miller part number, so fit is easy to check.
- Flex-in installation, per the listing.
Limitations
- Third-party, not Miller-branded.
- Fits only the helmets that use the 271320 cover.
- Ten is a lot if you rarely weld.

Frequently Asked Questions
What is the Miller 271320?
It is Miller’s front lens cover for Infinity helmets, listed at 6 x 5-5/8 inches. It protects the auto-darkening filter from spatter, sparks and scratches.
Will this fit all Digital Infinity helmets?
The listing says it fits helmets that use the 271320 cover, but verify your helmet’s part number or measurements before ordering.
Is this the same as the filter lens?
No. It is only the clear protective cover. The auto-darkening filter is a separate and much more expensive part.
Why does my new lens look cloudy?
Check for the protective film on both sides. If the cover is still hazy after removing it, do not use it.
Bottom Line
A good buy if your Infinity helmet uses the 271320 cover and you go through them. Confirm the part number first, since that is the main risk.
