Advantage 420 Quantitative Fit Test Adapter

The MSA Advantage 420 Quantitative Fit Test Adapter is a specialised accessory for respiratory protection programmes. It connects Advantage series full-face and half-mask respirators to quantitative fit-testing equipment. Safety managers and occupational-health professionals use it to verify that each wearer achieves a proper seal. The black adapter is compatible with Advantage 200 LS, 3000, 4000 and 420 models.

Sustained testing workflow

During a fit-test session the adapter remains attached to the respirator while the instrument measures particle concentration inside and outside the facepiece. It supports repeated donning and doffing cycles without degrading the mask seal or the adapter connection. The design maintains a stable sampling path throughout the test protocol so that results reflect actual workplace protection.

Replaces improvised sampling methods

This adapter replaces makeshift probe fittings or brand-mismatched kits that can introduce leaks and invalidate quantitative results. The jump is worth it when a respiratory protection programme requires documented, repeatable fit factors for Advantage series masks. It is not suited for qualitative fit testing or for respirator brands outside the MSA Advantage range.

Questions about this item

Does the Advantage 420 adapter draw any power or generate heat during all-day fit testing?

The adapter is a passive mechanical fitting with no electronics, so it consumes no power and produces no heat during extended use.

Which respirator models must I already own for the 10056424 adapter to connect properly?

It fits Advantage 200 LS, Advantage 3000, Advantage 4000 and Advantage 420 full-face and half-mask respirators.

Will the adapter seal correctly on an older Advantage 200 LS mask that I still use?

Yes, the adapter is listed as compatible with the Advantage 200 LS series, so it will seal on that model.
