Description
HTA adaptor nipples A are designed to provide a reliable transition between HTA CPVC pipework and threaded metal components within pressurised hot and cold water systems. Featuring a solvent weld CPVC end and a precision-machined male brass thread, they allow secure connection to valves, pumps and other threaded equipment.
The CPVC body offers excellent resistance to corrosion, scale and chemical attack, while the brass threaded insert provides strength and durability at the mechanical interface. The smooth internal bore supports efficient flow, helping to reduce frictional losses and maintain pump performance across the system.
Manufactured as part of the HTA system by Aliaxis, these adaptor nipples integrate seamlessly with compatible HTA pipes and fittings. Installation is straightforward, requires no hot works, and enables clean transitions between plastic and metallic pipe systems without compromising performance or compliance.
