Description
HTA adaptor nipples B are designed for connecting HTA CPVC pipework to threaded metallic components where a compact, pressure-rated transition is required. Featuring a solvent weld CPVC body combined with a precision male brass thread, they provide a robust and reliable interface for valves, pumps and other BSPP threaded equipment.
The CPVC section offers excellent resistance to corrosion, scale and chemical attack, ensuring long-term performance in hot and cold water systems. Internally, the smooth bore helps maintain efficient flow characteristics, reducing frictional losses and supporting consistent system pressures.
Manufactured as part of the HTA system by Aliaxis, adaptor nipples B are engineered to integrate seamlessly with compatible HTA pipes and fittings. Installation is quick and straightforward using solvent weld techniques, eliminating the need for hot works while enabling secure plastic-to-metal transitions.
