TruDesign Aquavalve 90° Hose Tail – BSP Composite Elbow Fitting

Optimise tight plumbing installations with the TruDesign Aquavalve 90° Hose Tail—a precision-engineered composite elbow fitting designed specifically for use with TruDesign Aquavalve systems.

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

The 90° angled design allows hoses to be routed cleanly around corners and confined spaces, reducing the need for sharp bends and helping prevent hose kinking or collapse. This makes it ideal for installations where space is limited or directional changes are required.

Designed exclusively for Aquavalve systems, the fitting uses a 1½″ BSP parallel thread, matching the Aquavalve body. Importantly, the thread provides mechanical connection only—sealing is achieved via the included thermoplastic rubber blue washer, ensuring a reliable, leak-free fit.

A key installation advantage is the rotational alignment feature—the blue seal allows the fitting to be rotated after tightening, enabling precise hose positioning without compromising the seal.

Engineered for demanding marine environments, this fitting is resistant to diesel, petrol, antifouling chemicals, UV exposure, and extreme temperatures (-40°C to +110°C), ensuring long service life and dependable performance.

⚠️ Important: This fitting is designed only for use with TruDesign Aquavalve systems and is not recommended for use with ball valves or standard threaded fittings.
