Description
HTA long pattern reducing bushes are designed to provide a gradual and hydraulically efficient reduction between pipe diameters within HTA hot and cold water systems. The extended body length allows for smoother flow transitions, making them particularly well suited to applications where pressure stability and reduced turbulence are important.
Manufactured from high-performance CPVC, long pattern reducing bushes offer outstanding resistance to corrosion, scaling and chemical attack, ensuring reliable long-term performance in both commercial and industrial water installations. The smooth internal bore helps maintain pump efficiency, minimise frictional losses and reduce the risk of scale or biofilm formation.
As part of the HTA system developed by Aliaxis, these reducers integrate seamlessly with compatible HTA pipes and fittings. Solvent weld assembly enables quick, clean installation without hot works, delivering a dependable and cost-effective alternative to traditional metal reducers.
