No More Cramped Spaces: Discover the Benefits of Serto's Radial System
In tight spaces and complex piping systems, every millimeter and every minute of installation time counts. As a proud partner of the Swiss company Serto, we at Colly Flowtech supply pipe fittings based on a unique radial system, designed to solve the challenges where traditional fittings fall short.
What makes the system so special, and what does that mean in practical terms for your facility, your installation, and your ongoing operating costs?
What makes Serto's radial system unique?
Traditional pumps, such as peristaltic or diaphragm pumps, rely on mechanical action; they... To understand the strength of Serto’s design, we need to look at how a conventional tube fitting is constructed. In traditional couplings, the sealing cone itself is integrated into the coupling body. Serto has opted for a completely reversed design in which the cone is instead located in the nut.
This innovative design principle means that the seal between the clamping ring and the coupling body is formed against a completely flat surface. As a result, integrated components in a piping system can be installed and removed radially—that is, straight in and out of the system.
With Sertos’ radial system, you won’t have to pry, force, move, or dismantle adjacent piping just to access a single valve, sensor, or meter in the middle of a complex network.
6 Practical Benefits of Sertos Radial Systems and Pipe Fittings
Through our partnership with Serto, we can offer a design that directly impacts your installation time, material consumption, and operational reliability. Below, we’ve listed six benefits of the system:
1. Minimal space requirements:
Since the components are mounted radially, no additional straight sections are needed to space the pipes apart. The piping can be routed along the shortest possible path, taking up minimal space.
2. Shorter downtime during maintenance:
The ability to remove individual components radially means you don’t have to dismantle the surrounding piping. This significantly reduces the time required for servicing.
3. High operational reliability and vibration resistance:
The nuts are equipped with a metric fine-pitch thread that is self-locking and designed to withstand severe vibrations. As a true compression fitting, neither the pipe nor the hose is damaged during installation, and the pipe’s full wall thickness is maintained.
4. Reduced inventory requirements:
The modular system is based on a small number of basic components that can be combined to accommodate different threads and dimensions. This reduces the number of items you need to keep in stock.
5. Optimized Workflows:
With short, straight pipes without unnecessary bends, you’ll save time while also reducing the pressure drop in the system.
6. Available CAD data:
To streamline the design process, free access to CAD data for all components is provided, which saves time during the drafting phase and minimizes the risk of incorrect dimensioning.

Here's how we'll help you every step of the way to the finish line
For us at Colly Flowtech, it’s about more than just delivering individual components in a box. We’re with you every step of the way, from the first CAD drawing to the final on-site installation at your facility.
With our extensive experience and Serto’s flexible systems, we help you eliminate unnecessary pipe bends, reduce the risk of leaks, and significantly cut down on total installation time. We ensure that you receive a solution tailored to your specific pressure, flow, and space requirements.
