Replacement Ear Muff Pad Kit

This kit supplies fresh ear cushions and foam inserts for compatible 3M PELTOR headsets. It restores the original fit and hygiene of the hearing protector without replacing the entire unit. The components are manufactured by Aearo under model HY79.

Maintenance for Alert and Tactical series

The pads suit users who own Alert, FM-Radio, LiteCom, ProTac or Tactical XP models and need routine cushion renewal. Buyers whose headsets fall outside these series should look at something else because the kit will not fit.
