No-Touch Push-to-Fit Single-Use Earplugs combine the comfortable wearing experience of ultra-soft foam with a superior earplug design. No-Touch Push-to-Fit format ensures the earplugs stay clean, even when your hands or gloves are dirty. Paddle-shaped, livewire-stem grips allow you to insert & remove your earplugs without touching the plugs themselves.

All No-Touch Push-to-Fit Earplugs are compatible with the 3M E-A-Rfit Dual-Ear Validation System. E-A-Rfit provides an accurate quantitative assessment of exactly how much noise-reduction a hearing protector will provide to any given worker.
