The flex connectors is composed of an inner and outer layer of rubber, a ply layer, and a loop, and is combined with a metal flange or parallel joint after vulcanization. It has heat resistance, acid resistance, alkali resistance, corrosion resistance, and oil resistance, and has been widely used in various pipeline systems.
1. Reliable decompression effect
2. Easy to adjust and operate
3. Low pressure loss, large flow rate, small volume, light weight, and good energy-saving effect.
4. Long service life, important components made of special materials, no need for maintenance.

Note: 1. Special requirements can be customized according to the user's drawings. The flange standard is GB / t9115.1-2000. A variety of flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. Rubber spheres can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene green rubber, fluororubber, etc.2. When the suspended water supply uses products above DN200, the pipeline must have fixed support or fixed bracket, otherwise the product should be installed with anti pull off device.


It is very important to select the appropriate flex connectors of the pipeline, understand the compatibility of the medium with the selected material, the full temperature, pressure and vacuum range, the required movement and the size between the pipeline flanges.
