At Secc, our purpose is to provide robust, safe, and efficient fluid transfer solutions that protect your personnel, assets, and the environment without compromise. For over two decades, our patented coupling technology has set the industry benchmark for performance, reliability, and safety in the most demanding subsea, marine, and industrial applications.
Our engineering philosophy is encapsulated in the Secc 19 Benefits, a comprehensive list of unique features that give our clients an unparalleled advantage over the competition. This isn’t just a list of features; it’s a commitment to a higher standard of performance and safety.

Secc’s designs are protected by patents in key global regions, which provides commercial protection and prevents competitors from mimicking our technology. This commitment to intellectual property ensures that our unique solutions remain exclusive to our clients, giving you a distinct advantage.
Our couplings are engineered and tested to provide zero through-seat leakage and zero leak after activation. We have developed and proven a variety of elastomer and polymer sealing solutions to achieve this, giving you confidence in every connection.
While some couplings minimise the swept volume between closures, our patented designs go a step further. Our QCDC (Quick Connect Disconnect) range minimises the cavity volume and uses patented cavity vents to reduce spill volume to zero. This is an essential driver for protecting the environment from fluid spills, especially when transferring hazardous materials.
All Secc couplings offer a full-bore design with no internal valve trim, providing excellent flow characteristics and high wear resistance. This allows fluids to be transfered at high velocity without compromising transfer time or cargo integrity.
Our simple bore geometry and full-bore design result in a comparably low differential pressure (Δp), even with 90°, 45°, or 35° bends. This simplifies system assessment and integration, unlike other valve closures that require complex CFD modelling to determine accurate pressure drop results.
The simplicity of our couplings balances the hydrostatic forces created by internal pressure without the need of compensation systems and large quantities of seals. This allows relatively low break loads to be adopted even at high pressure.
Secc’s geometry encapsulates the seat and body seals away from the product flow. This full-bore design eliminates complex mechanisms from the flow path. Prevents seat failure, seal/seat washout, making our products highly resistant to wear from abrasive or corrosive media like ammonia and hydrogen.
Our unique sleeve design autonomously covers and protects the probe and sealing surfaces once activated. This shields the ejected probe from potential impact damage, a risk that is common with other couplings that have exposed surfaces.
The valve closure, facilitated by the Secc probe and sleeve, can be isolated instantaneously or over a controlled period to prevent surge. The closure speed can be adjusted in situ, a feature that is not available with other common valved lightweight-couplings.
The valve closure is directly linked to the release and retention system, simplifying controls and auxiliary equipment. This interlocked design reduces risk by ensuring the system cannot be activated without the valve being closed first.
Secc’s technology is the ultimate “plug and play” solution. It can be operated via a simple axial push and pull or overridden hydraulically, without interfering with the passive function. This provides operational flexibility and peace of mind in the event of a malfunction or operator error.
Our probe and sleeve design enables a safe emergency quick disconnect (EQD) even under full working pressure and flow. This is a critical safety feature that removes the need to depressurise the system in an emergency, ensuring the EQD will not be compromised.
Our pressure-balanced probe design resists vacuum-induced effects. Once closed, it does not rely on springs or mechanical catches, ensuring it will not unseat due to negative pressure downstream.
The probe and sleeve design prevents the valve from closing unless an activation is initiated. This makes our couplings highly resilient against premature closures caused by flow surges, dense fluids, vibration, or wave motion.
Secc’s pressure-balanced technology removes separation forces caused by internal pressure. This means only a deliberate axial load, such as a hose pull or hydraulic override, can initiate activation, significantly reducing the risk of a spurious release.
Operators can always confirm the status and position of our couplings and valve closures. This is a vital safety feature, as many other systems do not provide clear position confirmation until the EQD is complete.
The design of our couplings allows for rapid resetting, with QCDC couplings taking minutes and passive breakaways (MLWL) resetting in approximately 20 minutes. This significantly reduces downtime and allows fluid transfer operations to resume quickly.
Thanks to Secc’s design philosophy , our couplings can be serviced and repaired quickly and efficiently with standard tools. This is a major advantage over other couplings that may require extensive remedial work and specialised tools.
Our couplings are designed to operate reliably in low-temperature environments, making them compatible with transitional fuels and supporting the energy transition.
