Solutions for Residential, Commercial, Water Mains & Fire Mains

Modern plumbing systems — in homes, commercial buildings, water mains networks and fire mains — require pipe and connection solutions that are reliable, flexible, low-maintenance and compliant with standards. Plasson brings decades of expertise in polyethylene (PE) pipe connection systems to meet these needs across Australia.

Whether it’s connecting household water, supplying commercial buildings, installing municipal water mains, or delivering water for fire-mains and fire protection, Plasson’s fittings and systems deliver proven performance and installation ease.

Why Plasson for Plumbing & Water Supply Systems

Versatile PE Pipe Connections for Any Plumbing Job

Plasson’s core mechanical compression fittings connect PE pipelines — from small residential water lines to large water mains — with a broad range of couplers, elbows, tees, adaptors, threaded fittings and more. Our compression range supports sizes commonly used in plumbing (20 mm, 25 mm, 32 mm), as well as larger diameters suitable for water mains and commercial supply lines.

Even for retrofits or where transition is needed, Plasson provides adaptors to connect PE pipe to copper, PVC, galvanised steel or other common plumbing materials — ideal for mixed-material building plumbing or upgrades.

Fast, Simple Installation: Push-Fit or Compression, No Specialist Tools Needed

The Plasson Series 1 push-fit range is designed for plumbing contexts where space or appearance matters (e.g. inside buildings, service cupboards, under floors). It connects PE (and compatible copper / PB / PEX) pipe using a compact push-fit design that provides a PN16-rated joint — making it suitable for most water supply and plumbing applications.

For larger or more demanding supply lines, Plasson’s compression fittings remain a robust choice: simple hand-tightening (plus a final turn for certain sizes) gives a secure connection without welding or fusion, reducing labour and installation time.

Durability, UV-Stability & Long Lifecycle for Australian Conditions

All Plasson PE fittings are designed for strength, UV stability, and resistance to environmental stress — making them suitable not only for internal plumbing but also for external, underground, or above-ground water mains supply.

Combined with rigorous manufacturing standards and decades of use in Australian PE pipeline systems, Plasson provides dependable fittings that minimise maintenance and reduce lifecycle costs.

Compliant for Water Supply & Fire Mains Requirements

For building, commercial, and municipal water supply — including fire-mains — Plasson’s fittings offer seal integrity, pressure rating (standard PN16 or equivalent where required), and compatibility with PE and transition to other pipe materials. This makes them suitable for potable water, building water supply, water mains distribution, and fire-mains/infrastructure use.

Applications

Residential

Engineered for the modern home, our residential range provides a Lead Free and zero-corrosion path from the street to the structure. Utilising our “Hand-Tight, Job Done” philosophy, these PN16-rated fittings require no specialist tools, ensuring rapid installation for water meters and garden reticulation. Our signature captive O-ring technology handles ground movement in new housing estates, providing a leak-free seal that is designed to outlast the home itself.

Water Mains

The security of any residential or commercial service starts at the main, and Plasson provides the high-performance bridge required for municipal connections. Our range includes the bolt-free Plassaddle, allowing for rapid, tool-free tapping into existing Metric PE (AS4130) or PVC (AS1477) networks without shutting down essential services. This civil-grade infrastructure ensures a secure, non-corrosive connection that maintains potable water quality for the life of the asset.

Fire Mains

Fire protection systems demand absolute reliability under pressure, which is why our dedicated fire main infrastructure is tested to PN16 standards. By utilising a fully welded SmartFuse network, we eliminate the risk of joint separation during emergency pressure surges. Unlike traditional metal lines, our poly infrastructure suffers no internal scaling or rust, ensuring maximum flow rates are available the instant they are needed.
