Find a supplier

No exact store listing is recorded for this part. Continue with the documented system parts record, the supplier directory, or contact the affiliated UK store or US store to identify the correct regional SKU. An enquiry is not a claim of current stock or that another SKU is a substitute.

The Face Mask Store (UK), USA Face Mask Store and this site have the same owner. These links are commercial enquiry routes.

Listing ≠ endorsement. Confirm availability, approval status and source evidence before purchase or regulated workplace use.

Remarques

Documented correction: a widely-circulated research report cited "KP3934-2" as the Viking filter — that number does not appear in Lincoln's own parts table, which lists KP3424-2 / KP3424-6. Exactly the class of error this database exists to prevent.
