Tru-Design, based in New Zealand, set out to solve some of the most persistent problems in marine plumbing. For decades, boat owners relied on metal fittings that were prone to corrosion and electrolysis, leading to constant maintenance and potential failures. Tru-Design saw an opportunity to innovate.

They developed a range of marine-grade composite fittings designed to eliminate these issues entirely. Their mission is to provide boat builders and owners with a complete, integrated system of skin fittings, valves, and connectors that are strong, lightweight, and completely immune to the harsh saltwater environment. This focus on creating a reliable, long-lasting system is what sets them apart.

Tru-Design's product line isn't just a collection of individual parts; it's a fully compatible system designed to work together seamlessly. The core components include:

• Skin Fittings (Thru-Hulls): These are the fittings that pass through the boat's hull, allowing water to enter or exit. They are the critical connection between the sea and the boat's internal plumbing.
• Ball Valves: These connect directly to the skin fittings, providing a secure way to shut off the flow of water in an emergency or for maintenance. Their smooth, full-bore design ensures maximum flow.
• Load-Bearing Collars: This is a key safety component. The collar fits over the skin fitting on the inside of the hull, distributing the load from the valve and attached hoses over a wider surface area. This drastically increases the strength of the entire assembly, protecting the hull from stress.

When combined, these parts create an exceptionally strong and reliable thru-hull assembly. The system is designed so that the threads are compatible and the installation is straightforward, giving builders confidence in the final product.

Tru-Design's choice of material is what makes their products revolutionary. They are manufactured from a glass-reinforced polymer composite. This advanced material offers several key advantages over traditional metals like bronze or stainless steel in a marine environment.

First and foremost is corrosion resistance. The composite material will not rust, corrode, or degrade when exposed to saltwater, eliminating a major failure point for marine plumbing. This also means they are immune to electrolysis, a galvanic reaction that can occur when different metals are in contact in water, often leading to rapid and unseen deterioration of metal fittings.

Beyond that, these fittings are lightweight yet incredibly strong. Their high strength-to-weight ratio reduces overall vessel weight without compromising on safety or durability. The material is also UV-resistant, so it won't become brittle or break down after years of exposure to sunlight.

To ensure their products meet the highest safety benchmarks, Tru-Design submits its fittings for rigorous independent testing. They comply with multiple international standards, giving boat owners and builders confidence in their performance.

Two of the most important certifications are ISO 9093-2 and ABYC H-27. These are globally recognized standards for seacocks and thru-hull fittings on small craft. Compliance means the products have been tested for strength, durability, resistance to temperature changes, and overall integrity in demanding marine conditions.

When you use a Tru-Design product, you are using a fitting that has been verified by third-party organizations to be safe, reliable, and built for the purpose. This certification is a critical selling point, as it provides a clear guarantee of quality and performance that goes beyond simple product claims.
