Kit contents and fit
This Peltor HYX4 hygiene kit supplies fresh foam inserts and replacement ear cushions for X-Series X4 earmuffs. It fits models X4A and X4P51E and restores the original seal and comfort. The cushions use black foam, polyurethane and PVC materials. The kit is CE approved and electrically insulated.
Compatibility check
Verify that your earmuffs belong to the 3M PELTOR X-Series X4 line before ordering. Cross-reference Grainger part numbers 21DE17, 21DE22, 475M53 or 52JH57 if those references are on your existing set. The kit will not fit other series or brands.
When to replace
Swap the pads when cushions harden, tear or lose their acoustic seal, which reduces the 27 dB noise reduction rating. Regular replacement keeps protection consistent for high-noise environments. Users who need a different attenuation level or a non-dielectric design should look elsewhere.
