When it comes to modern plumbing installations, reliability, flexibility, and efficiency are crucial. That’s exactly why more and more plumbers and heating engineers are turning to MLCP (Multi-Layer Composite Pipe) fittings.
At Monsterplumb, we’re seeing huge demand for MLCP fittings, and for good reason. These versatile fittings combine the advantages of both metal and plastic systems, offering a lightweight yet robust solution for a wide range of applications.
But what makes MLCP fittings so popular — and which brand should you choose? Let’s take a closer look.
The advantages of MLCP fittings
✅ Lightweight and easy to handle
MLCP fittings are significantly lighter than traditional copper or steel systems, making them easier to transport, cut, and install.
✅ High flexibility
Multi-layer pipes can be bent easily, reducing the need for additional fittings and joints. This speeds up installation time and reduces the risk of potential leaks.
✅ Corrosion-resistant
Unlike metal-only systems, MLCP fittings don’t suffer from internal or external corrosion, ensuring long-term reliability and minimal maintenance.
✅ Excellent thermal and acoustic performance
MLCP pipes and fittings help reduce heat loss and minimise noise from flowing water — ideal for both domestic and commercial projects.
✅ Secure and leak-free connections
When installed correctly, MLCP fittings provide a permanent, secure joint, giving both installers and end-users peace of mind.
