Structural Design
- The outer layer protects the surface of the bellows from ozone erosion and impact, which will reduce the service life.
- Spherical design for improved efficiency.
- Easy to assemble: Both ends are equipped with flanges made of high-quality stainless steel, forged to accommodate full rubber.
- Allows connection at different angles: axial compression and tension, lateral and multi-angle deflection.
- Robust design, made of nylon braided fabric, which provides high shell molding resistance while having high burst pressure, and can absorb noise and vibration.
- Both ends are equipped with reinforcement wires, and high-quality low-carbon steel strands provide greater consistency for the outer neck of the tube.
- Light weight, easy installation, small installation space required, replaceable bellows, easy maintenance.
- Full rubber design, self-sealing, no need for additional gaskets, can prevent electrolytic corrosion.
