Nauticus GA5002-20T Smart Tabs ST Series Gas Actuator with Boot 20 lb Pair

The Nauticus GA5002-20T is a pair of original equipment replacement gas actuators designed for the Smart Tabs ST (Stainless) Series trim tab system. Rated at 20 lbs. of force, these nitrogen gas pneumatic actuators automatically react to water pressure, boat speed, and payload — delivering hands-free trim adjustment with no switches or wiring required.

The actuator casing is made of black nitrate-treated metal with a rubberized coating, providing a life expectancy that exceeds standard stainless steel by up to 28%. Each actuator is sealed in an air-tight, chemical- and ultraviolet-resistant EPDM rubber boot to protect against the harsh marine environment. A color-coded zip tie identification system makes it easy to identify the correct actuator for your application.
