Yes. All internal metal components are stainless steel or aluminium to prevent rust. There are also drain holes at the bottom of the unit to allow any water to escape. All plastic components are UV Stabilized ( Except Acrylic signs and the PET Pump bottle) for outdoor application.
We recommend keeping the top cap (or an accessory) on the unit (especially for Pilot 5 and Pilot 10) is recommended during wet weather to help minimise water entry into the belt unit via the Twist-lok slots.
