318-1000 E-A-R Push-Ins EarPlugs

An inovative, simple-to-use design which features the ultra-soft performance of a tip made of patented E-A-R form foam.  The E-A-R form foam expands in the ear canal to create a comfortable seal against noise and provide an ooptimal protection level.  Plus, since the unique foam actually softens and becomes more pliable with body temperature, the seal and comfort increases the longer the plugs are worn.  The plugs stay seated with a gentle low pressure seal on the ear canal.  ANSI S3.19-1974/CSAZ94.2  NRR = 28dB
