Description
HTA threaded 90° elbows are designed to provide a compact right-angle change in direction while allowing a threaded connection to valves, equipment or metallic pipework. Combining a high-performance CPVC body with an integrated female thread, these fittings offer a practical and reliable solution for directional changes within HTA hot and cold water systems.
The CPVC construction delivers excellent resistance to corrosion, limescale and chemical attack, ensuring long-term durability even at elevated temperatures. A smooth internal bore supports efficient flow and helps minimise frictional losses, contributing to consistent system performance and improved pump efficiency.
Manufactured as part of the HTA system by Aliaxis, these threaded elbows integrate seamlessly with compatible HTA pipes and fittings. Solvent weld installation removes the need for hot works, providing a safe, efficient and cost-effective alternative to traditional metal elbow fittings.
