Description
HTA 3-piece unions F are designed to provide a demountable connection between HTA CPVC pipework and female threaded metallic components in pressurised hot and cold water systems. The three-part construction allows sections of pipework or connected equipment to be disconnected easily for inspection, servicing or replacement without cutting the pipe.
Manufactured from high-performance CPVC, the union body offers excellent resistance to corrosion, limescale and chemical attack. The integrated brass female thread provides a durable and secure interface with threaded valves, pumps and plant equipment, while the smooth internal bore helps maintain efficient flow and stable system pressures.
Produced as part of the HTA system by Aliaxis, this union is engineered to work seamlessly with compatible HTA pipes and fittings. Solvent weld installation combined with a demountable joint design makes it particularly well suited to plant rooms and serviceable installations where long-term access is essential.
