BRA.T8.500 - rubber expansion joint - threaded

The BRA.T8.500 threaded rubber expansion joints are designed for use in heating, ventilation, and air conditioning (HVAC) systems, as well as water distribution networks. These joints help absorb vibrations and compensate for thermal expansion and contraction in piping systems. They are suitable for water with up to 50% glycol content and operate within a temperature range of -10°C to +100°C.

Available with nominal sizes ranging from 3/4" to 3", these expansion joints feature female/female (F/F) ISO 228-1 threaded connections. The flexible element is made of EPDM rubber reinforced with nylon, while the threaded components are constructed from galvanized steel. They are certified for use in potable water systems.

How to choose

• Select the correct nominal size (from 3/4" to 3") based on the pipe diameter in your system.
• Ensure compatibility with ISO 228-1 threaded fittings for secure and leak-free connections.
• Confirm the operating conditions match the product’s specifications: max. pressure 16 bar and temperature range -10°C to +100°C.
• Verify suitability for water with up to 50% glycol content and avoid using in systems with steam, oil-based fluids, or hydrocarbons.
• Refer to the manufacturer’s technical sheet for required length compensation values during installation planning.
