Copper pipe and tube is classified into four different specification types based on wall thickness for a specific outside diameter. Products can be colour coded with cap as follows: Type A : Green Type B : Blue Type C : Red Type D : Black. There are also several tempers available, ranging from soft, to bendable, to hard drawn. Each unique item has an individual product code in our system.

Whilst plumbing tube in Australia is still sold in inch or imperial sizes, it is hard converted into mm or metric for ordering purposes. Contact us for free delivery on large orders.

Precision Engineering for Optimal Performance

Crafted with precision and engineered to perfection, copper tube offer unparalleled performance. Their smooth interior surface minimizes friction, enhancing fluid flow efficiency and reducing energy consumption. Furthermore, copper’s natural antimicrobial properties make it an ideal choice for conveying potable water, ensuring the highest standards of hygiene and safety.

Sustainable by Nature

In an era where sustainability reigns supreme, copper tubes shine as a beacon of eco-friendliness. With a lifecycle that spans generations, copper is infinitely recyclable without compromising its quality. By choosing copper tubes, you’re not just investing in superior functionality; you’re also making a conscientious choice for the planet.

Whether it’s for plumbing, HVAC, or any other application, copper tube offer unparalleled performance and durability. This piece highlights the myriad benefits of copper tubes, positioning them as a cornerstone of modern infrastructure and a symbol of excellence in engineering.

Inherent Strength

Copper tube has inherent strength, providing good resistance to external damage, puncture, abrasion, vibration bumps, and has a wide operating range for pressure and vacuum. Also good corrosion resistance.


Copper tube is impervious to oxygen, insecticide, solvents and toxins.


Copper pipe and tube is non-flammable and does not emit toxic fumes during fire.

Full Flow Joints

Copper pipe and tube jointing does not reduce the bore of the tube, maximising flow.

U.V. Resistance

Copper tube and pipe does not degrade from direct sunlight or become brittle with age.

Pancake coils

Also available in small pancake annealed coils.

Resistance Rodent Attach

Copper pipe and tube is not prone to damage due to rodent attack.

Multi Applications

Copper pipe sizes, copper pipe fittings and tube is made to universal sizes, not a unique brand size.


Copper pipe and tube does not creep with age and has 7 to 15 times less linear expansion than other materials with heat, and continues to perform at high temperatures.

Healthier and Non-tainting

Copper pipe and tube does not adversely affect the taste of water and can reduce the number of harmful micro-organisms. As seen in the well-publicised reports on the anti-microbial properties of copper.

Copper fittings

There is a wide range of copper plumbing fittings and methods for installation, such as silver solder, push fit and press fittings. Again these items are typically spoken in inches but ordered in metric sizes.
