Rubber Joint

Dafugui, located in Wenzhou, Zhejiang, as a source manufacturer, supplies End Face Fully Sealed Rubber Expansion Joints. The flange end face is integrally vulcanized with the rubber sphere without any seams or joints, fundamentally eliminating media leakage. It also provides displacement compensation and vibration damping, making it particularly suitable for chemical, vacuum, and high-pressure pipeline systems with stringent sealing requirements.

Dafugui, located in Wenzhou, Zhejiang, as a professional manufacturer and supplier, offers factory-direct and customized services for Single Sphere Rubber Expansion Joints. Also known as flexible rubber joint, vibration isolator, or shock absorber, this product consists of a rubber sphere and loose flanges, featuring high elasticity, high airtightness, media resistance and weather resistance. It effectively compensates for axial, lateral and angular displacements caused by thermal expansion/contraction and equipment vibration, while providing excellent vibration and noise reduction. Widely used in water supply & drainage, HVAC, fire protection, chemical, marine and other pipeline systems.

Dafugui, as a professional manufacturer and supplier, offers factory-direct and customized services for Double Flange Limited Expansion Joints. The product features a built-in double-nut limit device that absorbs axial displacement caused by thermal expansion and foundation settlement, and automatically limits movement when exceeded, ensuring system safety. Widely used in water supply, chemical, and power industries.

Dafugui, located in Wenzhou, Zhejiang, as a professional manufacturer and supplier, offers factory-direct and customized services for Double Flange Steel Expansion Joints. Featuring an all-steel structure with high strength and durability, this product effectively compensates for axial displacement and installation deviations, and is suitable for water, oil, gas, steam, and other media. Strictly manufactured in accordance with GB/T 12465 standards, with reliable quality and stable delivery, our products are exported to South America, the Middle East, Africa, Southeast Asia, and other markets.

Dafugui, located in Wenzhou, Zhejiang, as a professional manufacturer and supplier, offers factory-direct and customized services for Bellows Expansion Joints. This product consists of metal bellows, end pipes, flanges and other components. Through the elastic deformation of bellows, it effectively compensates for axial, lateral and angular displacements caused by thermal expansion/contraction, mechanical deformation and vibration in pipelines. Manufactured from stainless steel, it features excellent corrosion resistance, high/low temperature resistance (-235℃～+450℃), and high pressure resistance (up to 32MPa). Widely used in petrochemical, power, metallurgy and other industrial pipeline systems.
