NHFLEX-A TYPE HVAC Rubber Expansion Joint for High Temperature
The HVAC High-Temperature Rubber Expansion Joint is designed to absorb thermal expansion, vibration, and mechanical movement in heating, ventilation, and air-conditioning systems operating under elevated temperatures. Manufactured from heat-resistant elastomers and reinforced for durability, it ensures reliable performance, system stability, and long service life in demanding HVAC environments.
Application:
Water, Sea Water, Fresh Water, Warm Water, Weak Acid Fluid, Soda Fluid, etc. Pipeline
Connected with pumps, valves, firefighting equipment, etc.

Characteristics:
1. High-Temperature Resistance
Special rubber compounds provide excellent resistance to heat, aging, and thermal fatigue, making it ideal for hot water, heating loops, and air handling systems.
2. Thermal Expansion Compensation
Absorbs axial, lateral, and angular movements caused by temperature fluctuations, preventing stress, deformation, and leakage in HVAC pipelines.
3. Shock Absorption and Noise Reduction
Rubber expansion joints effectively reduce the transmission of vibrations and noise in pipeline systems, providing a quieter and more stable working environment.
4. Easy Installation and Maintenance
Lightweight design with standard flanged connections simplifies installation and reduces downtime and maintenance costs.
Standard Specification:
| Max.Working Pressure | 2.5Mpa | |||||
| Operating Temperature | -20ºC-100ºC | |||||
| Vacuum KPa (mmHg) | 44.9(350) | |||||
| Applicable Media | Sea Water, Drinking Water, etc. | |||||
| Flange Standard | DIN, JIS, GOST, ANSI, etc. | |||||

Compensating for Thermal Expansion and Contraction: Rubber expansion joints compensate for thermal expansion and contraction caused by temperature variations in the pipeline. They prevent excessive stress on the pipeline system due to temperature changes, thereby protecting the pipes from damage.
Absorbing Vibrations and Impacts: Rubber expansion joints absorb stresses caused by vibrations and impacts in the pipeline system, reducing the transmission of vibrations and noise. This helps protect the pipeline and related equipment from damage.
Compensating for Pipe Movements: During installation and operation, pipeline systems may experience certain degrees of pipe movement. Rubber expansion joints compensate for these movements, ensuring the proper functioning of the pipeline system.
Leak Prevention: Rubber expansion joints provide sealing performance in pipeline systems, reducing the risk of leaks and ensuring the safe operation of the pipelines.
