This Round Expansion Tank Bracket (Steel D42) is a compact, durable mounting solution designed for heating expansion vessels up to 25 liters, including Flexcon-type and other European-standard red expansion tanks. The bracket features five functional connection ports, allowing installers to assemble a complete heating safety group in one place: pressure gauge, automatic air vent, safety valve, and dual ¾" connections for the expansion vessel and the system’s return line.
Constructed from high-strength D42 carbon steel tubing and finished with a RAL3013 red powder coating, the console is corrosion-resistant and visually consistent with European expansion vessels. The integrated wall-mounting plate with two slotted holes allows either horizontal or vertical installation, making it ideal for boiler rooms, small heating systems, and renovation projects.
This bracket ensures a clean, reliable, and easy way to install expansion vessels while maintaining safety and system performance.

This Round Expansion Tank Bracket is suitable for a wide range of heating, hydronic, and pressure-control systems. Its 5-port configuration and D42 steel construction make it highly versatile for both residential and light commercial applications.
Ideal for:
Domestic boiler systems
Radiator heating networks
Floor heating (underfloor heating manifolds)
Heat pump systems requiring expansion control
The bracket provides a convenient and safe mounting point for expansion vessels and safety devices.
Suitable for hydronic circuits that require:
Pressure stabilization
Thermal expansion control
Balanced circulation in closed-loop water systems
The dual ¾" ports allow quick integration with return lines and circulation loops.
Commonly used in:
Gas boilers
Oil boilers
Electric heating units
Wall-hung and floor-standing boilers
It organizes safety components such as gauges, vents, and valves in one clean assembly.
Perfect for closed solar heating loops where temperature and pressure fluctuations are high.
The bracket supports solar-rated expansion vessels (18–25 L) and can withstand temperatures up to 99°C.
Used to stabilize expansion in hot water storage and indirect cylinder systems.
The bracket’s 5-port design allows installers to add:
Temperature/pressure relief valves
Air vents
Monitoring gauges
Modern heat pumps require stable pressure buffering.
The bracket provides a professional way to mount expansion vessels without floor space usage.
Applicable for:
Small commercial buildings
Rental homes and apartment heating systems
Small industrial circulation units
Pump stations and pressure control modules
The wall-mounted design saves space and standardizes installation layouts.
In retrofit projects where old brackets or welded supports need replacement, this unit provides:
Fast installation
Universal compatibility with European ¾" expansion vessels
A clean, modern appearance
Perfect for contractors upgrading existing mechanical rooms.
Manufacturers of heating equipment can integrate this bracket into:
Pre-assembled boiler packages
Expansion tank kits
Safety group modules
Wall-mounted heating panels
The 5-port layout offers great flexibility for custom configurations.
Choose a solid wall surface capable of supporting the expansion vessel's full weight.
Fix the wall plate using the two slotted mounting holes.
Attach the expansion vessel to the ¾" connection, either directly or via a quick coupling.
Install a pressure gauge, automatic air vent, and safety valve on the three upper ports (3/8" ×2, 1/2" ×1).
Connect the expansion line to the second ¾" port.
Seal all threaded connections using PTFE tape or thread sealant.
Fill the system, check pressure levels, and ensure there are no leaks.
This bracket fits:
Flexcon-type expansion vessels (18–25 L)
Reflex, Flamco, Aquasystem, Zilmet-type red heating vessels
Any vessel with ¾" male connection
Domestic heating systems, boiler systems, and hydronic circuits
Always depressurize the heating system before installation.
Check and adjust vessel pre-charge pressure (0.8–1.5 bar) before operation.
Ensure the safety valve outlet is unobstructed.
Install the expansion vessel upright for best performance and longer lifespan.
