Poly STH

In the ever-evolving world of plumbing solutions, innovation and adaptability stand as the cornerstones of progress. At STH Westco, we’re thrilled to unveil our latest and most advanced line of plastic pipe fittings, poised to redefine convenience, reliability, and efficiency in the plumbing industry. 

The Evolution of Plastic Pipe Fittings 

The days in which plastic pipe fittings were viewed with scepticism, deemed only for basic applications are now gone. Today, they have broken these limitations, offering huge advantages that cater to the diverse needs of modern plumbing & heating projects.

One of the key driving forces behind this evolution is the development of high-performance polybutylene materials. These materials offer superior strength, corrosion resistance, and freezing temperature resistance, ensuring longevity and reliability even in the most demanding environments. Additionally, advancements in plastic fittings have lead to the development of anti-oxygen barriers to stop the ingress of any oxygen in the system.

Polybutylene piping systems have demonstrated their effectiveness in European piping installations for nearly 50 years, making our latest PolySTH range a thoroughly established system with over 4 decades of proven reliability.

It’s a quick and safe system to install and requires fewer joins than rigid piping systems. The joints do not require solvents, soldering or flames making it suitable for no hot works. PolySTH is more resistant to impacts and freeze bursts than rigid piping systems.

Key Features & Benefits 

Our fittings offer a comprehensive array of benefits. Available in sizes ranging from 15mm to 28mm, they cater to various piping needs. Resilient against corrosion and freezing temperatures, they ensure durability in diverse environmental conditions. With low internal roughness, our fittings minimize pressure drops, optimizing system efficiency. Their lightweight nature facilitates easy handling and manoeuvrability during installation.

Equipped with an anti-oxygen barrier, our fittings prevent oxygen ingress into the system, enhancing longevity and performance. Ready for immediate use straight from the coil, they minimise downtime and facilitate swift installation. Ideal for a wide range of applications including hot and cold sanitary what supplies, central heating to radiators, and underfloor central heating installations. Our Polybutylene pipes are WRAS approved and come with a 25-year warranty.

Moreover, our fittings offer time-saving benefits with faster assembly and disassembly compared to other systems, improving overall efficiency. They require no tools for installation, ensuring a clean and hassle-free process. Boasting a secure joining system, they withstand temperature changes, hard water, and shocks, ensuring reliability and stability.

Additionally, their lightweight construction makes them easy to handle and transport, weighing less than a quarter of copper. This further enhances convenience and efficiency, making our fittings a preferred choice for plumbing and heating installations.

At STH Westco, innovation and customer satisfaction remain our guiding principles. Our new range of plastic pipe fittings represents our dedication to delivering premium-quality solutions that redefine standards in the plumbing industry.
