Completely designed, engineered, and manufactured by AST, TruLink combines the proven reliability, safety, and installation ease of the past with cutting edge material, engineering, and manufacturing technology.

TruLink is manufactured from high quality, marine-grade aluminum to provide the highest level of protection against corrosion. Our smooth bore, extruded tubing is manufactured in the USA and ensures that the media traveling through a system encounters very little turbulence, while enabling high flow rates with minimal pressure losses compared to conventional steel systems.

By utilizing aluminum, we guarantee a 30-55% weight reduction over traditional systems -making TruLink easy to install and modify. Also, aluminum is the best material choice for corrosion and rust resistance, so the system will remain operating at maximum efficiency for the duration of use.
