Key Features & Technical Highlights

1. Heavy-Duty Construction

Each Union Flexible Joint is built with a reinforced rubber body made of EPDM, Neoprene, or NBR to ensure maximum resistance against pressure, temperature, and corrosion. The bellows may be single- or twin-sphere shaped to enhance flexibility and accommodate greater movement.

2. Durable Union Ends

Fitted with galvanized steel, stainless steel, or cast iron threaded ends, the screw-type unions enable fast, secure installation without special tools or gaskets. This allows quick maintenance and reliable long-term sealing in pressurized systems.

3. Movement Absorption & Flexibility

The elastic rubber bellows absorb:

• Axial movement (compression and elongation)
• Lateral displacement (pipe misalignment)
• Angular deflection (tilt or bending)

This capability minimizes pipeline stress caused by thermal expansion, ground movement, or pressure surges.

4. Vibration & Noise Reduction

The high-elastic rubber body acts as a vibration isolator, preventing noise and vibration from pumps, chillers, compressors, and HVAC equipment from transmitting through pipelines — ensuring smoother and quieter operation.

5. Corrosion & Electrolysis Resistance

Since there is no metal-to-metal contact between flanges, the design eliminates galvanic corrosion, extending system life and reliability in all piping environments.

6. Leak-Free & Maintenance-Friendly

The precision-engineered threaded connection system allows for leak-proof sealing and easy detachment, making it the preferred choice for maintenance-heavy systems such as chillers, pumps, and water lines.

 

Common Applications

HVAC Systems

Used extensively in air conditioning systems, fan coil units, pumps, and chillers to absorb vibration, prevent noise transmission, and allow thermal expansion within building service networks.

Plumbing & Building Services

Ideal for water supply lines, drainage systems, circulating water loops, and water heaters, ensuring a flexible and leak-proof connection between pipelines.

Industrial Process Lines

Widely used in chemical plants, refineries, power plants, and manufacturing facilities to handle fluids like water, oil, chemicals, and steam, maintaining pressure integrity and vibration isolation.

Marine & Offshore Applications

Suitable for engine cooling systems, ballast water lines, and seawater handling, offering long-lasting performance even under harsh offshore and shipboard conditions.

Pumps & Compressor Installations

Installed at pump suction and discharge sides to prevent damage from vibration, misalignment, and thermal expansion.
