TruDesign composite fittings are manufactured using a glass-reinforced nylon composite. High strength, high-modulus glass fibres impregnated into the nylon provide increased strength, stiffness, toughness, and dimensional stability. TruDesign fittings eliminate the corrosion and electrical bonding problems associated with metal fittings. Tails (Hose barbs) are designed for twin hose clamps and to not crush under high load conditions.

• Parallel BSP or NPS threads - Universal compatibility with TruDesign fittings, and other common marine components
• For above the water line only when directly fitted to a Skin Fitting / Thru Hull. In below water line situations - ISO & ABYC require a TruDesign Ball Valve to be fitted directly to a Skin Fittings / Thru Hulls.
