No brand-matched suppliers are listed on this record yet. Check the supplier directory for the full evidence-backed directory.

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

Notes

Z3 uses a different breathing tube (04-832) — the couplers are not interchangeable between the two families. Short version for backpack assemblies is 04-841 (same headtop compatibility, shorter length).
