DN1800 Limited Tie Rod Epdm Elastomer Large Flexible Rubber Fully Seal Expansion Joint Rubber Expansion Bellows

End-face fully sealed rubber joint
The characteristics of this product are: the flange touches the end face of the sphere, which not only improves the high-pressure resistance of the product, but also plays a good role in preventing it from pulling off.

Installation Notes

1. Rubber joints should be installed according to the natural length of the product, and installation beyond the displacement limit is strictly prohibited.
2. The pipeline must be supported by a fixed bracket or bracket, and both ends of the rubber joint must have a fixed bracket. The closer the bracket and the rubber joint are, the better.
3. The force of the pipe fixing bracket must be greater than the axial force, and the joint must not bear the weight and axial force of the pipe itself.
4. Please install within the allowable value range of the product. Exceeding the range of displacement and deflection will cause the rubber joint to leak or pull off.
5. The bolts should be tightened gradually at the corners. Excessive tightening will damage the sealing surface.
