Steel crossover four-way switch - 12 1509057013

Application and Construction in Steel Installations

This component is a steel crossing tee, specifically designed for piping systems connected via press-fitting technology. Its primary function is to create a stable distribution node where the main pipe continues straight through (crossing), while simultaneously allowing a branch connection at a 90-degree angle. Thanks to the use of galvanized steel (Fe/Zn88 coating with a thickness of 8-15 µm), the fitting offers high corrosion resistance, which is crucial in heating and water supply installations where environmental conditions can be demanding.

It is worth noting the specifics of the connections – all three openings (main and side) are equipped with press-fit couplings. This solution eliminates the need for mechanical seals or adhesives, which could age over time. Instead, the system relies on the precise compression of the press ring against the pipe, ensuring tightness immediately upon installation. Importantly, for installers working in difficult conditions or under high loads, the product features a Leak Before Press (LBP) function. This means that in the event of a seal failure, the fluid will not spread chaotically throughout the facility but will be directed through a special channel to a location visible to service personnel, facilitating quick fault localization and repair.

Key Installation and Operation Features

Installing this tee requires the use of dedicated pressing tools, ensuring repeatability and speed of work. The "T with branch" construction allows for flexible routing of the piping network without the need for additional elbows or reducers at the branching point. The O-ring seal integrated into the fitting acts as a flow barrier, and its quality is directly dependent on the correctness of the press-fit connection.

For professionals, this means fewer components to order and reduced installation time – one element replaces several traditional threaded or welded connections. For the end user, durability and safety are paramount: the steel construction minimizes the risk of cracking under pressure or temperature changes, while the zinc layer protects against rusting for years of operation.

Key technical aspects of this model include galvanized steel (Fe/Zn88) with a protective layer of 8-15 µm thickness and a connection type based solely on press-fits on all ports. The shape of the crossing tee (T with 90° branch) facilitates the implementation of complex pipe routes, and the built-in Leak Before Press (LBP) function provides additional protection against flooding in case of O-ring seal failure.

Practical Application

This element is ideal for central heating installations and domestic hot water systems where high mechanical strength of connections is required. Thanks to the LBP function, it is particularly recommended for hard-to-reach locations or where a leak could cause significant material damage – the system automatically signals the problem before completely flooding the room.

• Quick Installation: Achieved by a single pressing tool action on each of the three connections.
• Durability: Ensured by the use of galvanized steel resistant to humid technical environments.
• Safety: The LBP function limits the consequences of potential seal failures to a controlled leak visible to service personnel.
• Versatility: The product fits standard steel pipes designed for the KAN-therm Steel press-fit system.

It should be noted that during installation, original pressing tools dedicated to the Steel system must be strictly used, and the manufacturer's instructions regarding clamping force and pressing cycle duration must be followed. Only in this way can full tightness and the realization of the Leak Before Press function be guaranteed throughout the entire service life of the installation.
