Structure and Feature

1. Small volume, light weight, good elasticity, easy installation and maintenance. 

2. Installation can generate horizontal, axial and angular displacement, from pipe barrier heart, flange is not parallel to the limit. 

3. Work to reduce structural transmission of noise, vibration absorption ability.

4. Good sealing performance and scalability, easy to use. Internal high density, can endure high pressure, elastic deformation effect is good. 

5. Use of rubber of high elasticity, high resistance, solvent resistance, weather resistance and radiation resistance and other advantages can  reduce vibration and noise,and play the role of  compensation for thermal expansion and contraction caused by temperature change. 

6. Standard sizes range from 1.25" through 80".
