Description
This HTA 90° elbow is designed to create smooth, reliable directional changes within pressurised hot and cold water systems. Manufactured from high-performance CPVC, it provides excellent strength and dimensional stability across a wide range of operating temperatures and pressures.
The fitting features a smooth internal bore that helps maintain flow efficiency while reducing frictional losses, limescale build-up and the risk of biofilm development. Its corrosion-free construction ensures long-term durability and consistent water quality, even in demanding installations.
As part of the HTA system manufactured by Aliaxis, this elbow integrates seamlessly with compatible HTA pipes and valves to form a fully certified, high-performance alternative to copper. Lightweight construction and simple solvent weld assembly allow for quick installation without the need for hot works or specialist permits.
