TruDesign Hose Tail Reducer Connector – Composite Hose Joiner (Unequal Sizes)

Easily connect hoses of different diameters with the TruDesign Hose Tail Reducer Connector—a high-performance inline reducer fitting designed for flexible and reliable marine plumbing systems.

Manufactured in New Zealand from glass-reinforced nylon composite, this reducer offers exceptional strength, durability, and resistance to corrosion and electrolysis, making it ideal for long-term use in harsh saltwater environments.

The unequal hose tail design allows seamless transitions between different hose sizes—perfect for adapting existing plumbing systems or integrating new components without complex modifications.

Engineered with long twin-barb hose tails, the connector provides a secure grip for hose clamps, preventing slippage and hose collapse under pressure—ensuring leak-free performance in demanding applications.

Designed for real-world marine conditions, the TruDesign reducer is resistant to diesel, petrol, chemicals, UV exposure, and antifouling coatings, and operates reliably across a wide temperature range from -40°C to +110°C.

Available in multiple size combinations such as 19→13mm, 25→19mm, 32→25mm, and 38→25mm, this fitting is an essential solution for bilge, sanitation, freshwater, and deck wash systems.
