TRUDESIGN 3/4" Thru-Hull Fitting | Certified for Below Waterline Use

Upgrade your vessel´s plumbing system with the superior safety and durability of the TRUDESIGN 3/4" Thru-Hull. Engineered as a modern alternative to traditional bronze or stainless steel fittings, this component provides unparalleled performance and peace of mind for boat owners who demand the best in marine equipment. Eliminate the constant worry of corrosion and electrolysis, and invest in a solution designed for a lifetime of reliability in the harshest marine environments.

Ideal for all hull types, this thru-hull fitting is a critical component in any boat´s plumbing system, serving as a secure and watertight pass-through for intakes or discharges below the waterline. Its innovative design and robust construction make it the first choice for new builds, refits, and essential maintenance upgrades.

Key Benefits of the TRUDESIGN 3/4" Thru-Hull:

* Complete Corrosion Immunity: Say goodbye to rust, dezincification, and electrolysis. Unlike metal fittings, this thru-hull is completely inert in saltwater and freshwater, ensuring the structural integrity of your hull and plumbing system for years to come without degradation.
* Exceptional Strength and Durability: Engineered to withstand high-impact forces, pressure, and stress, this thru-hull offers strength that rivals its metallic counterparts. It is built to handle the rigours of the marine environment, from hull flex to accidental knocks.
* Lightweight Performance: Significantly lighter than traditional bronze fittings, the TRUDESIGN thru-hull helps reduce overall vessel weight. This is a distinct advantage for performance sailing and racing boats, as well as for easier handling and installation.
* UV and Chemical Resistance: Formulated for longevity, the material is highly resistant to degradation from UV sunlight exposure. It is also unaffected by common marine chemicals, including fuels, lubricants, and antifouling paints, ensuring it won´t become brittle or weak over time.

Main Features:

* Designed to integrate seamlessly with TRUDESIGN Ball Valves and other components for a complete, certified system.
* Features a standard thread form compatible with most marine seacocks and plumbing fittings.
* The outer flange has a recessed, low-profile design for a clean, flush finish against the hull.
* The body of the thru-hull is splined, creating a superior locking surface for sealants to prevent leaks and stop the fitting from turning during installation.
* Includes a high-strength backing nut that provides a large surface area to distribute the load evenly against the hull, preventing stress cracking.
