PolyAlu Tubing: Revolutionising Durability in Harsh Environments
In the realm of industrial and engineering applications, the need for materials that can endure tough conditions without sacrificing performance is constant. Enter Megaflex Limited’s PolyAlu Tubing, a state-of-the-art solution crafted for a diverse range of uses, particularly those involving air and gas sampling, exposure to corrosive settings, pneumatic instrumentation, and control lines in notably damp or wet environments.

Construction and Composition
PolyAlu Tubing is made from aluminium tape coated with a co-polymer adhesive film. This construction ensures a sealed, overlapping seam that greatly enhances the tubing’s strength and longevity. Surrounding this aluminium core is a medium-density polyethylene (MDPE) jacket, carefully bonded to the aluminium. This dual-layer design provides PolyAlu Tubing with outstanding resistance to corrosion and chemicals, and allows it to be easily shaped by hand into desired forms, making it an excellent choice for numerous demanding applications.

Why Choose Megaflex Limited’s PolyAlu Tubing?

PolyAlu Tubing marks a notable advancement in materials technology, delivering robust solutions for applications where resistance to harsh conditions and durability are critical. Whether for industrial instrumentation, environmental monitoring, or intricate inspection tasks, PolyAlu Tubing offers performance, reliability, and adaptability, establishing a new benchmark for tubing in challenging and corrosive environments.
When selecting materials for industrial, aerospace, or environmental purposes, the stakes are high. Choosing between PolyAlu Tubing and traditional options like copper, PVC, or stainless steel can significantly affect your project’s efficiency, durability, and cost-effectiveness. In this detailed comparison, we examine why Megaflex Limited’s PolyAlu Tubing stands out as the superior option for a broad range of uses. Twin-tube version is also available.

Understanding the Contenders
Before exploring PolyAlu Tubing’s advantages, here’s a brief overview of traditional materials:
- Copper: Highly conductive and commonly used for thermal and electrical applications, but susceptible to corrosion and relatively costly. (e.g., Product code:
ICT-18 ) - PVC (Polyvinyl Chloride): Lightweight, transparent and economical with good resistance to chemicals and corrosion. However, it lacks the mechanical strength and temperature resilience required for more demanding uses. (e.g., Product code: C
Clear PVC TubeClear Unreinforced PVC Tube - Food Grade PolyVinylChloride Tubing) - Stainless Steel: Provides excellent strength and corrosion resistance but is much heavier and harder to install than other materials. It can also be quite expensive. (e.g., Product code:
ODT316L ) - Polyurethane: Known for its exceptional durability and flexibility. Unlike copper, which corrodes and is costly, polyurethane resists wear, tear, and various chemicals without a high price tag. It outperforms PVC with greater mechanical strength and temperature resistance, ensuring reliable performance in tough conditions. Compared to stainless steel, it’s lighter and easier to install, offering a versatile, cost-effective solution without compromising durability or resistance. (e.g., Product code: PU
Clear Polyurethane TubeHighly abrasion resistant tube designed for fuels, oils and pneumatics. Silicone and cadmium free.)
Enter PolyAlu Tubing

- Superior Corrosion Resistance: Designed with an MDPE jacket and aluminium core, PolyAlu Tubing offers exceptional resistance to corrosion and chemicals—ideal for harsh environments where copper and steel falter. It’s a strong alternative to Dekabon Synflex 1300 Tubing (Product code: DEK
Dekabon Tube Synflex 1300 TubingDekabon Tubing / Synflex 1300 Tube - Malleable Metal Tubing Coated in HDPE Cover). - Unmatched Flexibility and Ease of Installation: Its malleability allows it to be shaped by hand without losing rigidity, perfect for tight spaces where rigid materials struggle. Lightweight and easy to transport, it cuts labour costs and installation time compared to stainless steel or copper.
- Durability and Environmental Resistance: Despite its flexibility, PolyAlu Tubing is tough and durable, withstanding environmental challenges that degrade other materials. It handles temperature fluctuations better than PVC, which has limited capabilities.
- Cost-Effectiveness: Beyond initial costs, PolyAlu Tubing’s ease of installation, low maintenance, and long lifespan make it more economical over time than copper or stainless steel, which incur higher expenses due to weight and complexity.
- Wide Range of Applications: Its robust design suits uses from air and gas sampling to aerospace inspections, offering versatility that copper and stainless steel can’t always match without extra modifications.
