Product Description
Product Description
Overview of Flexible Rubber Expansion Joint
Designed to reduce vibration and noise, our Single Sphere Rubber Expansion Joints (KXT Type) are the ideal solution for protecting your piping systems. Made from high-quality vulcanized rubber (EPDM/NBR) and reinforced with nylon cord fabric, these joints offer superior elasticity and durability.
They are widely used in pump connections, water treatment plants, HVAC systems, and fire-fighting pipelines to absorb thermal expansion and correct piping misalignment. Whether you need standard Carbon Steel flanges or premium Stainless Steel flanges, we provide the perfect fit for your project.

Overview of Flexible Rubber Expansion Joint
1. Superior Vibration & Noise Reduction: Our single sphere design acts as a "shock absorber" for your pipeline. It effectively isolates the mechanical vibration from pumps, fans, and compressors and significantly lowers the noise level in the operating environment.
2. Premium Material & Durability: We use 100% new vulcanized rubber instead of recycled rubber. This ensures excellent resistance to aging, ozone, and weathering. The body provides high tensile strength to withstand high pressure without ballooning or bursting.
3. Smart Design for Easy Installation: Rotating Flanges: Unlike fixed welded flanges, our flanges are floating. This allows installers to easily align the bolt holes even if the pipeline is slightly twisted.
4. High Safety Factor: Designed for PN10/PN16 standard working pressure. Every batch undergoes strict testing. The burst pressure is 3 times the working pressure, ensuring maximum safety against water hammer or pressure surges.

Application
Municipal Water Supply & Drainage Systems
HVAC Systems & High-Rise Buildings
Petrochemical & Industrial Process Pipelines
Widely used in water treatment plants, sewage pumping stations, and municipal pipelines. Installed at the inlet and outlet of water pumps to absorb strong vibration and prevent pipe bursts caused by water hammer. It protects expensive pump equipment and extends the lifespan of the pipeline network.
Essential for central air conditioning systems (chillers, cooling towers) in hotels, hospitals, and commercial buildings. It connects circulation pumps and piping systems where silence is critical. It's excellent noise reduction and vibration isolation capabilities ensure a quiet environment for the building.
Designed for harsh industrial environments, conveying oil, acid, alkali, or high-temperature steam. Used in oil refineries, chemical plants, and steel mills. We provide specialized rubber materials like NBR (Oil-resistant) and FKM/Viton (Chemical-resistant). It compensates for thermal expansion and contraction in complex piping layouts while resisting corrosion.

FAQ
Q: How do I choose the right rubber material for my application?
A: It depends on the medium. generally: EPDM: For Water, Hot Water, Steam, and Weak Acid; NBR: For Oil, Fuel, and Hydraulic Fluid; PTFE/Teflon Lined: For strong corrosive chemicals. If you are not sure, just tell us the medium and temperature, and we will recommend the best one.

Q: What flange standards can you provide?
A: We can supply flanges according to ANSI B16.5, DIN 250, JIS 10K/20K, and BS 4504. Since the flanges are rotatable, they are very easy to align with your existing pipeline.
Q: Can you produce the product with my own brand?
A: Yes, we support OEM service. We can vulcanize your Brand Name or Logo onto the rubber body, and print your logo on the packaging box.
Q: What is the maximum temperature the rubber joint can handle?
A: Standard EPDM rubber joints can handle temperatures from -15°C to +115°C. If you need higher temperature resistance, please contact us for special High-Temp Rubber solutions.
Q: Do you have products in stock for fast delivery?
A: Yes, for standard sizes (DN32 to DN500) with PN16 Carbon Steel flanges, we usually have a large stock. Small orders can be shipped within 7 days.
