In recent years, press fit systems have emerged as a game-changing solution for streamlining piping installations.

Their ability to deliver reliable, efficient and cost-effective alternatives to traditional tube joining methods has made a significant impact across numerous industries. The results have been nothing short of transformative, offering a modern approach that meets the demanding needs of today’s industrial environments.

With exceptional material quality, innovative designs, proven reliability, and an extensive range of press fitting systems, Ibex Australia is at the forefront of this revolutionary technology.

This guide provides an in-depth overview of press fitting technology, covering everything you need to know – from how they work and their key advantages to best practices for installation. 

What is a press fitting?

A press fitting is a cutting-edge piece of technology that uses a hydraulic press tool to join two pieces of pipe or tubing together. The metal-to-metal connection provides the mechanical link, while the sealing element ensures a watertight and airtight seal.

In press fittings, the sealing element is typically an O-ring made of high-quality materials like EPDM (ethylene propylene diene monomer), FKM (fluoroelastomer), or HNBR (hydrogenated nitrile butadiene rubber). 

This O-ring is crucial to the fitting’s effectiveness. It sits inside the fitting and compresses when the hydraulic press tool is applied. The compression of the O-ring against the pipe or tubing creates a watertight and airtight seal, preventing leaks and ensuring the durability of the connection. 

While traditional tube joining methods require heat-based equipment, press fit technology doesn’t. A specialised press tool is all you’ll need. This eliminates the risks associated with high temperatures and provides you with a faster installation, and a more secure connection. 

How do press fittings work?

Press fittings work by creating a secure, leak-proof connection between pipes without the need for heat. This process involves using a battery-powered hydraulic tool along with specialised jaws and rings designed for the specific material being used.

The process involves inserting the pipe into the fitting, which contains a sealing element (like an O-ring) and a metal sleeve. The press tool then compresses the fitting, creating a secure, leak-proof connection by crimping the sleeve tightly around the pipe.

To give you a better understanding of how press fit technology works, here’s a simple, step-by-step breakdown of the process:

1. Cut

Start by cutting the pipe to your desired length with a suitable cutting tool. Make sure the cut is straight and clean to provide a proper surface for the fitting. A precise cut is crucial for the integrity of the connection. 

2. Deburr

Next, use a deburring tool to deburr the cut ends of the tube both inside and outside. This step is important for removing sharp edges, burrs or debris that could potentially damage the sealing element or interfere with the fitting process. Having a smooth, deburred surface creates a secure and leak-free connection.

3. Witness mark

Apply a witness mark on the tube at the appropriate insertion depth. This mark serves as a visual guide to confirm that the tube is fully inserted into the fitting during assembly. 

4. Assemble

Insert the tube into the press fitting until it reaches the witness mark, making sure it’s fully aligned and seated. The fitting contains an O-ring, which seals once pressed. 

5. Press

Using the appropriate pressing tool (along with an adaptor jaw and collar for larger sizes) securely press the fitting, creating a strong, leak-proof connection.

Here’s a detailed look at five unique benefits you can expect from Ibex Australia’s press fit systems:

1. Superior durability and corrosion resistance

At Ibex Australia, we craft our press fit systems from high-quality stainless steel, offering you exceptional durability and resistance to corrosion. This makes them ideal for environments where exposure to moisture, chemicals or other corrosive substances is common, providing you with a long-lasting and reliable connection.

For example, piping systems in chemical processing plants are regularly exposed to high-pressure steam and corrosive chemicals. Ibex’s stainless steel press fit systems are perfect in environments like these. Our press fittings maintain their integrity without cracking, leaking or corroding, even in temperatures that fluctuate drastically from extreme heat during operation to cooler conditions during shutdowns. This exceptional reliability ensures the safety and efficiency of your entire system.

2. Quick and straightforward installation

Press fitting is a remarkably innovative method. Because it doesn’t require heating equipment, the process is significantly faster and more straightforward, allowing you to connect pipes in a fraction of the time it traditionally takes to heat and join pipes.

Press fitting’s quick and simple installation process can also save you a significant amount of time, making them ideal for projects with tight deadlines. 

For example, in a commercial building project with a tight schedule, Ibex’s press fit systems enable quick piping installation without welding or soldering, significantly speeding up the process and keeping the project on track.

3. Multiple applications for different industries

Ibex’s press fit systems are compatible with various materials, including stainless steel (304L and 316L), carbon steel and black iron. This versatility makes them suitable for a broad range of industries and applications, from water and gas distribution to hydronic heating and fire protection.

To further highlight this versatility, you could use Ibex’s press fit systems for:

• Distributing water and gas in a residential complex.
• Installing hydronic heating systems in office buildings.
• Installing fire protection systems in industrial warehouses.
• Installing clean, sterile pipes for pharmaceutical water systems.
• Providing safe, corrosion-resistant piping for transporting non-consumable fluids in production lines, such as cleaning agents or cooling water.
• And so much more!

4. Leak-proof and secure connections

We design all of our press fittings with advanced sealing technology, ensuring a watertight and airtight seal. The robust design of these fittings allows them to perform exceptionally well under high-pressure conditions. This makes them a supremely reliable choice for critical applications where failure is not an option.

For example, in an offshore oil rig, Ibex’s press fit systems are used to handle high-pressure fluid transport, where the advanced, airtight design ensures that the fittings maintain a secure connection.

5. Cost-effective solution

Our press fit technology is remarkably efficient. The simple installation process not only saves time, but also significantly lowers labour costs, requiring fewer specialised skills than traditional pipe joining methods.

What’s more, because our press fit systems are extremely durable and corrosion-resistant, they require fewer maintenance checkups and provide a longer service life. Over time, this will offer you tremendous cost savings, making Ibex’s press fit systems a highly economical choice for both small- and large-scale projects.

What are some challenges with press fitting systems?

By now, you’re likely well-acquainted with the numerous advantages that press fitting systems offer over traditional joining methods. However, it’s equally important to be aware of some potential challenges. Understanding these challenges will ensure you’re fully prepared to maximise your experience with press fit technology.

1. Specialised tools and training

Press fit systems require specific tools for proper installation, such as a battery-powered hydraulic press and custom jaws or rings. Without these tools, you won’t be able to achieve reliable and secure connections.

Press fit systems also require specific training to use the tools correctly and ensure a secure fit. Improper use of press tools or incorrect tube preparation can cause leaks or weak connections, or even damage to the tools themselves.

2. Compatibility issues 

Press fit tools and fittings are often material-specific. This means that different jaws and rings are required for different pipe materials like copper, PEX or stainless steel. 

3. Difficult to modify after installation

Once a press fit connection is made, it is permanent and cannot be easily modified or adjusted without cutting the pipe and installing a new fitting. This lack of flexibility can be a drawback in situations where adjustments need to be made after installation.
