Seal

This is a genuine OEM replacement part that has been sourced directly from Senco. This seal is commonly used in nailers, electrics drills, and staplers. This o-ring is used in the valve assembly and provides an air-tight seal. Like most o-rings over time this one will wear down, due to the friction and heat it faces it will become brittle, and it might crack or break apart. When that happens the seal will no longer be air-tight, and the o-ring will need to be replaced because it is not effective. To successfully replace this part you will need an allen key/wrench, and a pair of pliers. This o-ring is made of rubber, and it is sold individually.
