JIS 200mm Rubber Joint Pipe Galvanized Rubber Duct Expansion Joints
End face fully sealed rubber connection is an improved product based on the KXT soft single-ball rubber joint. It combines high pressure resistance, excellent elasticity, large displacement capacity, anti-aging properties, vibration damping, and noise reduction. The improved design with limiting screws allows movement within a specified range while maintaining a sealing surface diameter matching standard flat welding flanges.
- Compact size and lightweight design for easy equipment maintenance
- Accommodates lateral, axial, and angular displacements without requiring perfectly parallel pipes or flanges
- Effectively reduces structure-borne noise transmission with superior vibration absorption
- Seamless high-pressure construction with materials resistant to temperature extremes, acids, alkalis, and oils
- Wide application across chemical, construction, water supply, petroleum, heavy industry, and power sectors
