Why Tru Design Composite Marine Fittings Are a Game-Changer for Modern Boats
Whether you’re refitting an old hull or building a new boat from scratch, the choice of fittings can make a huge difference in long-term performance, maintenance and safety. That’s where Tru Design composite marine fittingscome into play: engineered specifically for the harsh realities of life at sea, these innovative components offer clear advantages over traditional metal hardware.
Lightweight But Mighty: Strength Without the Weight
One of the hallmarks of Tru Design fittings is their construction from glass-reinforced nylon composite — a material that combines impressive strength with a notably lower weight compared to bronze or stainless steel alternatives.
This means less overall weight on your vessel (which is always a plus for performance and fuel efficiency), without losing structural integrity where it counts. These fittings are designed to be both stiff and tough, offering high dimensional stability even in fluctuating temperatures and rough seas.
Corrosion-Proof and Electrolysis-Free
Saltwater is one of the toughest enemies of boat hardware. Traditional metal fittings — even high-grade alloys — are susceptible to corrosion, galvanic reaction and electrolysis that can compromise integrity over time.
Tru Design’s composite materials are completely immune to corrosion and electrolysis, meaning:
-
no rusting or pitting over time,
-
minimal maintenance, and
-
no need to worry about complex bonding strategies to prevent electrolysis.
This resistance also extends to chemicals commonly found around boats, including diesel, petrol and antifouling paints.
UV Stability: Ready for Years Under the Sun
Boats spend a lot of time exposed to sunlight — and that UV exposure can degrade components that aren’t built for it. Tru Design fittings are UV resistant, so they won’t break down or discolour with long-term sun exposure the way some plastics can.
This durability is a huge advantage for fittings mounted above the waterline, where prolonged sunlight is a constant factor, and also contributes to long service life overall.
Certified for Safety and Versatility
Tru Design products aren’t just tough — they’re tested and certified to marine standards. Many skin fittings meet ISO 9093-2 international standards for non-metallic thru-hull fittings, and when paired with correct ball valves and collars, comply with safety norms such as ABYC H-27.
This means these fittings aren’t just rugged — they’re marine-grade components you can trust in critical applications.
Products That Highlight the Benefits
Here’s a snapshot of popular Tru Design composite fittings that showcase these advantages in real applications:
Through-Hull & Skin Fittings
-

Easy Installation and Low Maintenance
All of Tru Design’s composite fittings have been engineered with installation simplicity in mind — whether you’re a professional rigger or a DIY boater. Their lightweight nature makes positioning easier, and because the material doesn’t corrode, there’s no need for regular sanding, polishing or bonding checks.
Final Thoughts: A Modern Alternative to Metal
Marine environments are unforgiving. Traditional metal fittings — even when made from brass or bronze — can wear, corrode and demand regular maintenance. Tru Design composite marine fittings sidestep many of those headaches by offering:
✔ Exceptional corrosion resistance
✔ UV and chemical stability
✔ Lightweight strength and dimensional stability
✔ Certified reliability for critical applications
✔ Long service life with minimal upkeep
If you’re looking to upgrade your boat’s plumbing, seacocks, thru-hulls or fittings with products built for the realities of saltwater service, Tru Design should definitely be on your shortlist.
