Fittings

Our HTA hot and cold water fittings are designed for modern domestic and commercial water installations where long-term performance, safety and reliability are essential. Manufactured from a combination of CPVC, brass and stainless steel, these fittings form part of a fully matched HTA pipework system engineered specifically for the pressurised distribution of hot and cold potable water.

Positioned as a high-performance alternative to copper, the HTA system delivers consistent flow, excellent durability and simplified installation across a wide range of building types.

HTA fittings are manufactured from chlorinated polyvinyl chloride (CPVC), a material chosen for its outstanding mechanical, thermal and hygienic properties:

• Excellent resistance to corrosion, limescale and chemical attack
• No risk of internal rusting or material degradation over time
• Smooth internal bore to reduce frictional losses and maintain flow efficiency
• Reduced opportunity for biofilm development and bacterial growth
• Suitable for long-term potable hot and cold water distribution

These characteristics make HTA fittings particularly suitable for:

• Residential housing
• Schools and universities
• Hospitals and healthcare facilities
• Hotels and leisure buildings
• Commercial and public-sector developments

HTA is a high-performance pipe and fitting system designed to distribute high-temperature water at pressure while maintaining system integrity over its full service life.

• Designed for continuous operation at elevated temperatures
• Suitable for ISO 10508 application classes 2 and 4
• Proven resistance to short-term overheating and malfunction conditions
• Maintains structural integrity under pressure and temperature cycling

Fire performance is a key consideration in modern building design, particularly in public and multi-occupancy spaces. HTA exceeds expectations in this area:

• Classified B-s1,d0 (Euroclass)
• Highest achievable fire classification for a synthetic piping system
• Low smoke production and no flaming droplets
• Supports compliance with stringent building safety requirements

The smooth internal surface of HTA fittings provides several long-term operational benefits:

• Reduced frictional losses help maintain pump efficiency
• Lower energy demand compared to rougher-bore pipe systems
• Minimal scale build-up helps preserve system performance
• Reduced conditions for harmful bacteria to develop

Together, these features contribute to a safer, more efficient and more sustainable water network.

HTA fittings are designed for fast, straightforward installation:

• Lightweight and easy to handle on site
• No hot works required - no flame, soldering or welding
• Reduced installation time compared to copper systems
• No hot-works permits needed
• Simple training requirements

A wide range of CPVC-to-metal transition fittings is also available, allowing HTA systems to connect seamlessly to other pipe materials where required.

By combining thermal performance, fire safety, hygiene benefits and installation efficiency, HTA hot and cold water fittings provide a dependable solution for modern plumbing systems. Designed to meet demanding regulatory standards while offering long-term cost and energy efficiencies, HTA is an ideal choice for both new-build and refurbishment projects.
