Flexible joint
・The amount of eccentricity and expansion/contraction can be increased.
・The bending angle is large.
・It can also handle twisting.
・Toughness and high corrosion resistance.
・The cross-sectional shape does not change even if it is eccentric.
・Products inspected by the Japan Water Works Association (65A and 125A are excluded because they are not in the standards of the Japan Water Works Association)
・Maximum operating pressure: 1.0 MPa
*This diagram is a representative example. The shape and specifications may differ depending on the diameter and eccentricity.
