3M Peltor HY79 Replacement Hygiene Kit for Flex Headsets
If you rely on your 3M Peltor Flex headset for daily communication and hearing protection, keeping it in top condition is essential. Over time, ear cushions and foam inserts can degrade, compromising both comfort and the acoustic seal. The 3M Peltor HY79 Hygiene Kit provides a quick and easy way to refresh your headset, ensuring you maintain optimum protection and hygiene without needing to replace the entire unit.
Why should I replace my headset's sealing rings?
Regularly updating your headset's ear cushions is crucial for maintaining a tight seal around your ears. The replacement sealing rings included in the HY79 kit restore the original noise attenuation levels of your Peltor Flex headset, ensuring you stay fully protected in loud environments while maximizing all-day wearing comfort.
Which headsets are compatible with the HY79 kit?
This hygiene kit is specifically designed for the 3M PELTOR FLEX series of headsets. It is a direct fit for models including the MT53H79A-77, MT53H79B-77, MT53H79P3E-77, MT1H7F2-77, MT1H7P3E2-77, and MT1H7B2-77.
What is included in the replacement kit?
The HY79 package gives you everything needed for a complete refresh of both earcups. It contains one pair of replacement rubber ear covers (sealing rings) and the corresponding replacement foam inserts.
